Can you please make your videos without the acronyms and speak to the layman as well? We're here to learn, the most us that is... just my two pennies...with inflation and all maybe it's worth what it is.
Oh the hate in the comments! (chuckles) Some command-line tools for dealing with serial "AT" modem-like devices: minicom - A simple terminal program cu uucp uuencode uudecode - Old unix-2-unix suite for call-up, copying etc 7-bit-clean Quick note, even inexpensive uart-to-usb bridge devices usually have a "DTR" or "RTS" pin, that can be connected to the RST (reset) on your LoRa device ... a low pulse, sometimes through a little capacitor. Test this in minicom by sending a "Hangup".
Just a FYI it has already been done several times if you check on YT here. Might save a bit of coding time. Honestly you'd be better off using meshtastic for the mesh relay to far extend how far the Lora has to cover for something like this. These UART/AT command style modules do NOT work with meshtastic, but you can probably use painlessmesh arduino lib or look into using the ClusterDuck protocol which also can mesh/relay thru.
I literally have a lora module and a GPS module on my desk right now. I'm just having trouble getting Eclipse to recognize my USB programmer on my dev system or I would have done exactly that last night!
“Wireless technology” suggests the absence of cables or wires for the transfer of signals and “fidelity” meaning lasting support. These two words combine to spell out the definition of Wireless Fidelity or simply WiFi
@shadmansudipto7287 no. Thats actually comparing apples to oranges. They are not the same in any sense. At least with calling this "wifi" its still a form of wifi technology (WIRELESS). Internet, wan, and lan can USE wireless tech but it is not inherently wireless like wifi nor is it a network communication protocol or tech. Its just the type of network you have.
LoRa is regulated by FCC as well (It’s just license free similar to the ISM band but you do have some limitations, which when exceeded means that you’re disobeying the law. You don’t need a license to use a cordless phone as well). By the way this regulation limits the number of messages that are allowed to be transmitted every hour by limiting the transmission duty cycle to between 0.1% and 1.0% per day depending on the channel. Another note, it’s quite easy to triangulate such a device to find the transmitter so beware when you disobey the law. Also you forgot to mention that the fastest transmissions speed for LoRa is 22Kbps (kilobit, not kilobyte) which will only work for short range communication (not much of a WiFi replacement lol). In order to increase the range to the numbers you’ve talked about you have to reduce the speed to be 0.3kbps or slower. At maximum speed at 1% duty cycle you’re limited by law and not allowed to transmit more than 2.376 megabytes per day. There are less limitations on LoRa for HAMs in case the transmission is in one of the HAM bands (for example some LoRa chips use the 433Mhz band). This case requires a license and has some other limitations. For example encryption is not allowed as well as you’re required to transmit your call sign every time you start a transmission and every 10 minutes of transmission.
Yes, that is all true. Still pretty sure no one at all will concern themselves with any of that (Except the Ham guys who seem a bit obsessed over those kinds of laws and regulations) Nor is there any chance you'll be tracked down by suits walking around waving directional antennas all over looking for a Lora transmissions or a meshtastic relay on a hilltop some place. Even if they do go out, they do find it, they do take it, well... then for 26.00 I'll put up another one. No one is having their name and address silked onto these lora modules as far as I've heard.
@@williamna5800 Ironically, it is not the government who would cause you problems, but those obsessive ham radio guys who feel it is their duty to rat out anyone that hasn't jumped through all the same hoops as them. The gov't learned long ago that they don't need to pay people to monitor this stuff, because neurotic losers will do it for free, purely out of conformity and spite. These guys literally have lingo to describe the practice of tracking down 'unlicensed' communications.
@@williamna5800 The thing is that Amatuer-Class licensees have ZERO issues self-policing unauthorized activity in their licensed spaces, ESPECIALLY when it comes to flooding and other forms of RF contamination. There are Official Observers (OOs) (and as of 2020, new Volunteer Monitors) who are HAMs that have been trained & authorized to file official reports of incidents. If it's bad enough, triangulating a signal is not hard, and these "Fox Hunts" are often done for fun at HAM Festivals, like a radio-based game of tag. Finding a rogue transmitter is just a sport to HAMs, so if someone is going to be a pest and hurt the community by DoS'ing the local RF bands, HAMs CAN and often WILL track them down. And they'll do it quickly because they think it's fun and a community service at the same time!
"By the way this regulation limits the number of messages that are allowed to be transmitted every hour by limiting the transmission duty cycle to between 0.1% and 1.0% per day depending on the channel." doesn't this only apply when communicating with a LoRa-wan gateway provider? if not i might have hypothetically broken the law... hypothetically of course.
@@nathanahubbard1975 yes that is so ridiculous, these youtubers are jsut the new whores, they would do anything for audience, not a bit of integrity or even doing basic homework.
good intro... but for now what you said is just straight bullshit. LoRa is regulated to use different frequency in different part of the world, like 915MHz, 867MHz, 433MHz, and then there is the data rate, right now, LoRa theoretically top out at around 250kbps with 2.4GHz LoRa specification. You can't even watch your own video with that kind of bandwidth. You are misleading those people who don't have a strong background. In no world will LoRa replace WLAN. Then again, if your are already using 2.4GHz band, why not use Wifi then? It has way more bandwidth and crucially generally supported by most devices nowadays. If you would like to use on DIY project, why don't use a ESP32 then? It just as easy to use and it's way cheaper then LoRa modules. You are a very smart guy and I did learn a lot from watching your other videos, but probably should have done more digging before making this video.
yes, typical youtuber i would say, A lot of bullshit and a very gullibe audience.ISM It is true that the 1280 can reach about 250kbps, therorical, but the range will be pretty shitty at this point, less than 1km with easy environement. With the 1262 at 868 or 915M it will be more like 25kbps, with 1% duty cycle max.
Well, tbf he did say you wouldn't be sending video or even images this way, but I didn't like the "what _they_ don't want you to know" BS aspect of it.
I can think of one reason to use this over wifi despite the bandwidth difference. Okay, two. 1.) It's free, after its initial purchase that is. No service charges. 2.) It's decentralized. Hence the no service charges. But that's about the end of my limited knowledge of these. They're still neato. :) I'd like to get my paws on a couple for info purposed and general tinkering. Maybe you can tell me if these are suitable replacements for IR transmission generally found in the likes of radio-controlled gadgets like drones and RC cars or whatnot. I'm fairly green at this Arduino and esp32 stuff and there are soooo many possibilities out there that sometimes it takes a while even to correctly identify a controller module exactly as the IDE would know it to be when I buy a new, unfamiliar board. (It's been a blast, though. :) This rabbit hole is deep and super fun!)
@@NopeOnARope_ You can perfectly host a Wi-Fi hotspot at no charge and you are legally allowed to. You don't need an internet subscription at all. You could make a similar point with LoRaWAN, which is often a paid service. The reasons why you would use LoRa in the 2.4GHz band would likely be range and battery use, since I expect that the LoRa modulation would be much more resilient than Wi-Fi, even at an apparently way lower transmission power. I've seen some experimentation that showed good results even indoors, which I really doubt would have been remotely feasible with Wi-Fi. I actually recently researched the use of LoRa for RC cars. My opinion is that you can completely give up on using anything else than a 2.4GHz transceiver, because in sub-GHz you are too tight on bitrate, duty cycle limitations (PLEASE RESEARCH THOSE if you're planning on emitting at any high rate on sub-GHz bands, there is NO sub-GHz band you can legally use at such speeds without greatly reducing transmit power!) and the per-message overhead is too significant to make sense. And if you want telemetry, which is where using a custom radio makes sense in the first place, you're sort of screwed unless you drop the update Hz to sluggish levels. LoRa and real-time communications mix poorly by design. Especially accounting to the fact that the LoRa preamble/header is a lot of overhead for very short messages. But I'm still actually exploring the 2.4GHz band for RC car uses for the meme. For other RC stuff, especially autonomous RC vehicles, it makes a ton more sense because there actually seems to be a point to very long range low bitrate uses: updating waypoints, sending some return to home signal, receiving occasional GPS/accelerometer telemetry, idk I've never done drone/plane/boat RC stuff :)
These are amazing little modules, easy to use with simple Serial control and insane range. Using decent tuned DIY antennas they easily make 11 miles LOS so far. As a side note: no reason for the "wifi killer?" thumbnail thing, kinda clickbaity for something that is in no way at all related to wifi. That's like showing a picture of a Ford Focus with "Learjet killer?" You can't really run to the corner store in a Jet and you can't drive a Focus across an ocean, why pretend to compare them?

"This microchip can send datas 12 miles away", no, it is not a "microchip", it ia module, composed of an MCU and a transceiver, none of which is made by the brand you affiliate, as a side note i find it funny enough these modules have the shape of a pigeon, it seems appropriate i would say.
there is a swiss youtuber, who toys around with lorawan (european bands) and he tested it in alpine settings. connect to a known base station from a mountain, with a good antenna: maximum range 200km. or in other words: the main problem is suddenly the earths curvature. totally scary idea: what would be required for EME (moonbounce). regular moonbounce transmission require more than 100W sending power, way more than what lora specs allow. but since the requirements for a successful connection are lower too, a few watts might be sufficient.
Incase you've been living under a nuclear reactor burning hotter tan any heat you'd want to be anywhere near though providing a nice warmth from a perfect distance........Shesh how could something like that exist! Right? So, unless you're living under this nuclear ball.....the earth .is actually flat....therefore unlimited transmission distance!!!
@@TheKuptis Look it up, FE was a seventies joke thing, small ads in the back of Private Eye and Punch magazine, membership cards for the FE club. Humorless people took it as a serious thing.
"Wifi killer"?? I don't think so. If you exceed the 0'1% duty cycle you can be fined a very-very-very expensive fine. (Up to 1 million euros.) This technology is designed mainly for sensors and IOT devices. And I think it's awesome.
This is only partly true, as the duty cycle is very dependent on the frequency plan. I've only checked both of the EU bands, but some channels in those allow up to 10% duty cycles at reasonably high transmit powers for some channels, and even 100% duty cycles on very specific channels albeit at a much reduced transmit power. Don't quote me on it though, I had to dig up ETSI documents that i probably don't fully comprehend :) As for the 2.4GHz ISM band, for which there actually are LoRa transceivers, it basically just seems like a far west with no duty cycle limitations that is even harder to search legal info for. Finding such information with limited prior knowledge was surprisingly difficult. The thumbnail (and to some extent the title) is tiring clickbait. The comparison with Wi-Fi makes zero sense when you consider any conceivable usecase, unless you were using the wrong tool to start with.
@@OurSpaceshipEarth Most transceivers that I could find (that are meant to be used in end nodes, anyway) are indeed half-duplex only. Realistically, you are very much at the edge of LoRa's usecases if you need something that resembles full-duplex, and you probably have too high a bandwidth requirement anyway.

Haha Was thinking that I'd been the one who has been saying baud(bɔːd) wrong! Weird hearing the term without being preceded by digits! (1200, 2400, 9600)
To be fair, Emile Baudot, after whom the term is named, would be pronounced roughly bow-doh in French, so consistent with his pronunciation of "baud". But yeah, it's almost universally pronounced more like how a Brit would pronounce "board".
@edwardfletcher7790 I've always heard it as "BOD" like body. I had a BBS (Bulletin Board System - Pre-Internet) in 1986 at 1200 BAUD. I remember when I started using 2400 BAUD in 1990! Those were the days!
I spent several years in the Industrial controls industry and the company I worked for made hardware and software peripheral devices for Programmable Logic Controllers of different vendors. Our serially connected devices used the computer's serial port (9-pin or 25-pin) and, although versatile it was bound by the slowness of the UART (pronounced "You-art"). (UART stands for Universal Asynchronous Receiver Transmitter). The data rate of the UART is known as the Baud Rate (pronounced "bod rate"). Nobody in the industry (and I spoke with a LOT of engineers and systems integrators) ever called it the "boud rate". It's baud, rhymes with "Maud".
@@lauralhardy5450 Maybe, it bothered a lot of people if you read through the comments. Many people also pointed out hyperbole and just wrong information.
I just commented yesterday (bragged) to the whippersnappers that "when i got online we had to dial the modem manually w AT then launch the PPP cause win95 shipped w broken dialupnetworking (till MSWin95_DUNupdate1_2.exe) came around. I realized when I was nostalgiazing openly all over myself, that this had been my first shell account - cool.
Probably not many, because so many of these devices use variations of the Hayes AT command set, it would be rare to find someone who knows about Hayes but hasn't seen at least one of the thousands of similar devices still using it.
He does say a 'modem chip' at some point. I used to use commands like this to control mobile handsets over Bluetooth, for sending and receiving sms messages.
Just an FYI, 'BAUD' rate would rhyme with Applaud, Maraud, Fraud, etc. It is not pronounced like it rhymes with Loud, Cloud, or Shroud. GREAT video though, well done.
lol! thanks! I was thinking exactly this! I've been shuffling electrons since the early 70's and it took me a second to realize he was just mis pronouncing "baud"
It is a curious subject when it comes to duty cycle laws. They state one thing, but then you look at the smart meters in the ISM band that act as repeaters, where they are constantly sending out a blip.
you basically need to be a hacker to know how this will work, I think MAYBE if they start selling from Amazon a completed unit ready to install with a few clicks to work on an individual basis to communicate with "Close Friends and Family" the Limitations is really a bummer, but in the days of BBS before internet this was like the same thing... how to send text msgs over phone lines (of course then as well you couldn't use your land line for communications.
Back in 1960 I at 5 to 7 yrs old,was given a small device( radio) that you clamped onto a lampshade steel bracket( back when lampshades used a brass or steel shade bracket),or some peice of steel.it was able to pickup radio stations with no battery and worked on static electricity . It had a volune control and staion changer,was the size of half a cigarette.
So called "crystal radios" were one the first types of radio receivers and pulled power from the broadcast signal itself. They connected to an earth ground and had a wire antenna, and a very small number of parts. The ones I've seen used a earphone and didn't have a volume control due to the low amount of power available, there was just a frequency adjustment to select the AM station. They did not work with FM.
@@HarmonRAB-hp4nk It doesn't have anything to do with static electricity, the original commenter was incorrect in that part of what they said. If you are interested in the old time tech, look up the entry for "crystal radio" on Wikipedia.
In the 70's we had the ZN414 IC a fabulous little thing, with AGC too. At its bottom end i can pick up 160m radio amateurs as when I bumped into a CW contest, terrible selectivity at that point but certainly captured the thrill of schoolboy radio making.
Do you guys think it would be possible to transfer temperature and humidity with some of those gadgets with a low energy usage? Would be cool to have in some sort of winter storage, motorhome cabin etc.
FYI, UART is generally considered an acronym, not an initialism. That means you pronounce it "yoo-ahrt" (like a word), not "yoo-ay-ahr-tee" (individual letters).
The video is completely click bait hyperbole. The poster is totally incompetent on the subject matter, and they don't care. The video did exactly what it was supposed to, got him a bunch of views.
I am a little suspicious about the helix antenna, if it is a quarter wavelength antenna then it requires a groundplane to work properly, the groundplane creates an image of the field from the antenna. assuming that the groundplane is infinitely large, in reality the groundplane only has to be larger than the wavelength to do a decent job. I do think this antenna is optimized for size not antenna gain. Thus large improvements can be done. remember that the E / B field decays with the distance 1/r^2
new because the antenna is bs,,,, I make antenna's lol wifi g/n is 6cm and... thats a coil not an antenna lol ps range? LOL to get wifi passed 15 miles requires heavy amplification and dirrect line of sight
I have a perfect idea for safety and lora. It would keep people safe. I think I will try to build one to test out. A simple esp32 or other microcontroller, a single sensor and an emergency call button is all that is needed to hike with, and a simple reciever tied to a cellphone as a base station would be able to make an emergency call if there is an issue. The hardest part is the what if sections of the code. But it would be a cool project
@11:46 You are measuring the current drawn by the USB interface chip as well as the RYSL current. You ought to measure in the Vdd line going into the RYSL device to get a real value - my guess/hope is it is much less than 20mA. 20mA at 3V is not low power. This is huge for a battery iot device.
Expanding on your idea, integrating multiple sensors such as weather stations, seismographs, and smoke detectors into a mesh network powered by solar panels offers a robust and cost-effective solution for monitoring and protecting large, remote areas. As previously mentioned, by expanding beyond a basic weather station, you can incorporate additional devices such as a seismographs or smoke detectors. These interconnected devices can be deployed in various remote locations such as forests, mountainous areas, or even pipelines. By utilizing a modest power supply and a small solar panel, these devices can operate continuously. Through a mesh network and a gateway connection, data can be transmitted to a central station in real-time, enabling the collection of data over a wide and protected area. This approach can streamline the hardware requirements, which would typically cost thousands of dollars, by developing applications for these compact and cost-effective devices. Ultimately, if a user is to enter one of this areas, he can have one device with simply a gps and 2 way audio that can cost around 90 usd that can be connected to the complete network and have you and the safety teams of your stats... just saying
"traditional terminal like bash" - haha, was using AT commands via a "terminal" before linux was born in '91 Love this video... having flash backs to the 80's, with acoustic couplers and basic programming - just like your doing now! this is amazing!
@@DanielRisacher AT command set came out in the early 80's, originally designed by Hayes Microcomputer Products for their acoustic modems. It eventually became the de-facto standard of all acoustic modems.
The idea of installing remote weather stations with this tech is brilliant. I recently was introduced to a website called the Weather Underground, which is a network of community run weather stations. Someone in my area has one because there's no government station there, and the weather does differ substantially to the neighbouring stations, so we will be able to use it to monitor when to do certain tasks, like watering the garden. But there are similarly exposed peaks to your Mt. Washington not far from there either. Mt. Bogong ... the tallest mountain in the state can have radically different weather to the trailheads for climbing it. A weather station transmitting using LORA would only need to have line of site with a server that's connected to the internet to handle this. Genuinely a brilliant idea.
weather underground like 2 decades ago is how I learnt the short form of "Weather" for elitist weather nerds is "Wx", aka us cool ppl :). Sure was a great resource esp so long ago and prolly today for areas without overlapping gov/corp meteorological info like we get in cities..

Well, that's the Anglified sound, but the guy was French so you have to pronounce it in French: Baudot, which is definitely not 'bod' or 'bowd'. Can't help it that English doesn't have an 'au' sound.
You can achieve the same with Bluetooth, but not WiFi. Actually I managed to get over 10 miles range with Bluetooth. This is how it works: As you increase the bandwidth, or the amount of frequencies required to transmit something the shorter the range becomes. It uses more energy to spread the radio energy over more frequencies. The less frequencies / bandwidth you use the more energy goes into each frequency. Therefore narrow band has much longer range at the same transmit power level that goes into the antenna, callsed EIRP. Now further you can use a helical monopole antenna like they did which has a higher gain on the horizontal plane if held vertically. If you uncoil it the gain will increase. Directional antennas like planar, yagi and so on can achive 15 dbi or more gain. This means that you will achieve 6x to 8x the range. Using correct antennas, correct bandwidth, correct coupling, grounding, etc you can make RF do magic. Looking for RF advice, there are many resources online. Be careful though it is very easy to have 1 thing wrong and get 1/100 of the range that you otherwise could get. It is because signal propagation is exponential. You must get it right.
In it's heyday, traditional Internet phone modems were 56k (56,000 baud rate). This is roughly twice as fast and can be faster utilizing compression.Only the protocols and translation overhead, and possible security protocols must be accounted for. Analogous to early DSL, ISDN. So a wireless phone modem technology. An enterprising group can build a decent communication system over this that can include audio and video with compression. I like it.
i think you missed that when he set the 115200 baud rate, that was only the bit rate for the USB to UART bridge. at 8:50 to 8:54 he said LoRa is meant for about a hundred bytes every 10 to 15 minutes, which is a much lower data rate. and wireless data transmission rate depends on other factors, like the LoRa module settings, distance between nodes, interference. but generally the point of LoRa is in the name, Long Range. and to get the long range it means a lower data rate
lol internet phone's? at 56k? funny, I though they came out AFTER the INTERNET........ giving the net in 1980 was 4 websites... and none of them offered phone's
My Fastweb mobile connection is rarely above 10kb/s so I think this sounds promising ;-) My Vodafone FWA station provides 1kb/s at this very moment. So consider how these giants slow us down .....
Nice video! For future reference: UART -> pronounced "yoo-art", letter "U" then "art" Baud -> pronounced "bod" like part of body This is standard pronunciation in the engineering community in the US.
I remember back in the day when modems were measured in bauds some made the joke of saying it that way or a play off tge word body or bods. Its kinda like schedule (sked jule) and schedule (she jule) both are correct..and yes i notice the phonics suck
Very cool video! Thank you for making it. I have been interested lately in LoRa stuff and your very basic introduction was a breath of fresh air compared to a lot of what I have seen lately. I'm an old guy: I've been doing computing since early 1970s. That's back when we had to carve our 1s and 0s outta stone. UART is pronounced "you-art". BAUD is pronounced "bawd". I was exactly like you in my youthful days. I spent my hours reading and learning and working on ideas with boundless enthusiasm. Talk to some folks and you'll learn things like these pronunciations and it's also a great way to share what you know. RUclips is, of course, also great for that.
Awesome video! One question is this is a Transceiver can this be used to analyze and capture wifi data packets to try and figure out whats going on with a wifi project im working on? I dont know that much im just getting started with more complex tasks with my RPi4!! Like how could i use this to see the wifi information or packets being sent between devices, when theyre using a 5.8GHZ Wifi protocol from everything i can find about it? Or what would be a cool project to make to use these in?
Absolutely not, they're completely different. You're just asking for Wireshark, and if you need something lower-level, I don't think there is much consumer-tier hardware to save you.
@@asuasuasu I'm trying to capture the WiFi video used on my digital VTX from my RC airplane with an FPV camera on it.. The WIFI signal is 5.8ghz and i can select where in the Band more specifically using the CH's. 1 thru 8. Which are just spaced out so other people can fly with you.. However as far as i know the WiFi signal is going directly from the MIPI camera to the Digital Video Transmitter over WiFi (encrypted i think) and straight to the Goggles which have 5.8ghz LHCP Antennas on it for the Video Receiver (VRX) and then out to the Googles Display screen.. However there's no way right now to let other people watch what you see in the goggles except with a small phone screen over USB-C from the Goggles in a very low resolution.. We were trying to make a VRX that we can hook up to a screen. Then eventually try and downsize and build into a portable monitor setup for spectators (and spotters) basically.. Any ideas on what i should research and try first using Wireshark and maybe any other programs? Would any devices be useful for this like a flipper zero or is that not really useful for this? If I'm only using Ethernet on my PC for the Internet.. Can i use my current WiFi-6 Card for WireShark, or do I need something special for this kind of work?
@@mxracingunlimitedltd7784 Sorry, my knowledge of Wi-Fi is rather limited here. I don't really know if your usecase is actually using the Wi-Fi protocol (as opposed to just a custom radio that happens to use the same frequency band), and if it involves a regular access point that regular devices can connect to. You'd probably want to first dig up details on how exactly it works if anybody has done the work. As for wireshark, some chipsets/OSes may have different limitations with regards to listening to packets while not connected to an access point but I don't recall the specifics (especially in modern Wi-Fi).
It's baud pronounced like bod. The work baud comes from Baudot en.wikipedia.org/wiki/Baudot_code. It was shortened to just the first syllable in common usage.
Exactly! Thank you! I've always heard it as "BOD" like body. I had a BBS (Bulletin Board System - Pre-Internet) in 1986 at 1200 BAUD. I remember when I started using 2400 BAUD in 1990! Those were the days!

@@arxmechanica-robotics I think your splitting hairs here. I think the differences you're pointing out can be attributed to regional accent. Northeast vs. South for instance.
As soon as he said the the module was capable of sending "over 12 miles" and "this video may not be up for long" I lost any faith in his legitimacy and stopped watching... That antenna's not going far and the conspiracy theory is banal. I'm not going to waste my time on such stupid and misleading clickbait...
Sorry to bust your bubble but as a guy who has been into radio for 19 years now, I can tell you that we have used LORA at altitude and gotten 10 miles out of it so it is possible.
I have used these chips. They worked for under 2 miles in a rural area. I consider that pretty good. But it is not WiFi killer. You can only send short messages over long range. Good enough for switching devices remotely but not much else. Thank you.
Our local farmer had a system installed to run automation around the farm( around here it's a flat as a kippers dick,so in theory they had half a chance) It was promised to be capable of sending small data packages for irrigation and location systems,turn on pumps,valves etc. Noticing it being all being removed about a month after it was fitted I I took the opportunity in the pub that night to grill the the farmers son who incidentally is a fibre optics engineer. He stated that it just didn't work,its limited capacity wasn't capable of controlling some of the devices dependant upon it,it had poor and varying signal performance,was apparently susceptible to interference and easy to intercept/interfere with,admittedly the last not really a problem for a farm.but I'd imagine the farmer still expected it to at least work. Upon further conversations,their new set up is a Motorola system that was in his words "not much dearer but leagues ahead in performance". much like anything,if these cheap little devices were as good as stated their use would be widespread.
For your distance testing, would it be beneficial to set up a ping and return, rather than only counting, so latency and dropped message ratio can be visualized? Also, I missed how two or more nodes which have the same address and frequency would be differentiated.
Just bought a pair of cheapo ones, I'm a ham radio nerd so I'm going to try to adapt a SMA port instead of the coil antenna and put a dipole up on a 10 foot pole and see how far I can reach it.
NOTE: It's just slow serial data. Essentially, it's just a wireless rs232 link. Which is the oldest and slovest serial link u can get. A few kbs at best. For wifi, we're talking mbps, or even gbps. So don't mistake this with wifi or 4g 5g or anything fast.
Very interesting. Can I connect it to laptop or tablet to extend the capacity to connect to my internal home wifi? Can we call this device a wifi booster?
would it be possible to route internet to one device then use lora to link it to another device and make a wireless access point elsewhere? i just got a couple of these to try this project because i got a spot where wifi cant reach.
I could see the usefulness in this. Even though the baud rate is pretty low, you could still use it for flying UAV’s (remote control aircraft) long distance and still have plenty of room for long distance point to point missions. As long as the aerial vehicle is within line of sight (as directed by the FAA) and it’s not flying in controlled airspace (pilot will need to use a NOTAM for flight planning). I’m not even sure if I said that right. If there are any pilots out there who are willing to correct me, then please feel free to do so. I’m wanting to study for the part 107 exam so I can fly drones commercially and get paid for doing so. If anyone has any great tips, again, let me know.
Another reason you may have rx in the parking garage is radio reflection off a near by structure. I will have to check this out I have several potential applications I may be able to adapt to this. Thanks.
Yes the problem of those devices are that there are limits to their allotted data rates per time period. The way they seem to work is basically they set up an in line serial connection, which I guess you could use like modem point to point protocol at probably a horrible rate to literally get the internet. I was thinking of the IDEA, not even really starting, of how I could get internet from my parents where they are like 25 km away. All in all there is not a great way of doing it. I guess if there was a high point I could shoot 2 invisible lasers at a building and look for the other spot on the building for their signal. There is no socially nice way to do it. Today I just have a 110GB cell plan that costs about $110 Canadian a year.
Is the cell phone reception good at your location? If the reception is good then you probably have the best option atm. Cell phone towers have backup power during any electric outages which is a plus. However if your signal is bad, then you might consider a starlink system. The base price is $120 dollars per month unlimited data. The only catch is it does perform worse in stormy weather conditions. Average speed for canadian users are around 100 Mbps down and about 15 Mbps upload.
I am a little confused by the range test. If it was going thru wifi then the range did not matter because the signal you received on your phone came thru via the phone towers near you and had nothing to do with the range of the Tx. I understand radio but still I may be mixing stuff since I dont know much in this field.
Biggest problem is when everyone within 12 miles has one in a place like New York city with all the skyscrapers. We could have 1,000,000 people trying to send messages all at once. It would be all lag and messages colliding. Making the device useless. WIFI has limed number of channels. That's another reason why WIFI has limited range. If WIFI had a mile range it would also be unusable.
I agree with many commenters that the title of this is a bit click-baity, but the video otherwise does a very great job of introducing and displaying the capabilities of LoRa. It also gives enough information for creating a basic implementation. My son and I used this video to get LoRa working as part of a school science fair project, thanks to this video. Meanwhile, I am going to ask a technical question for any power users of the RYLR998, or similar devices.... As in the video, in a serial terminal, when connected directly to the RYLR998, I can get the UID using AT+UID? I need to query for this UID from WITHIN my Arduino application, and assign it to a variable, so that the UID can be forwarded to the receiving LoRa radio for unique source identification. Any pointers on how to format this code? Much appreciated!
That is amazing to be able to send/receive data several miles using only a few hundredths of a watt. Maybe extend range with obstacles with an RF amplifier if you can sacrifice the power.
I want to setup some thermo sensors in some out buildings to read and report temperatures every 30 min or so. This might be perfect to use with an RPi Pico and a temp sensor to send data for computer collection by a daemon/server, display on a web page, and send alerts to me if thresholds are passed. It is key for low power, long range small payload data comms but it ain't replacing WiFi.
cool device, i was wondering if it would work for my system to maybe increase my devices connection? i am currently using a samsung s8 as my mobile hotspot, connected via the USB for USB tethering into a PC. is there a way to open the phone and add the system to it to increase the range or strength of my data connection? i dont mind modding a bit and 3d printing a new case for it.

Quick note, even inexpensive uart-to-usb bridge devices usually have a "DTR" or "RTS" pin, that can be connected to the RST (reset) on your LoRa device ... a low pulse, sometimes through a little capacitor. Test this in minicom by sending a "Hangup".
A cheap way to ping your lost pet and get a simple gps location returned without some kind of subscription would make a lot of people happy.

Great idea... I might design it....
Just a FYI it has already been done several times if you check on YT here. Might save a bit of coding time. Honestly you'd be better off using meshtastic for the mesh relay to far extend how far the Lora has to cover for something like this. These UART/AT command style modules do NOT work with meshtastic, but you can probably use painlessmesh arduino lib or look into using the ClusterDuck protocol which also can mesh/relay thru.

@@imacmill It would be true if the LoRa Alliance isn't composed by industry giants and if they blatantly make the hardware open source.
LoRa is regulated by FCC as well (It’s just license free similar to the ISM band but you do have some limitations, which when exceeded means that you’re disobeying the law.
You don’t need a license to use a cordless phone as well).
By the way this regulation limits the number of messages that are allowed to be transmitted every hour by limiting the transmission duty cycle to between 0.1% and 1.0% per day depending on the channel.
Another note, it’s quite easy to triangulate such a device to find the transmitter so beware when you disobey the law.
Also you forgot to mention that the fastest transmissions speed for LoRa is 22Kbps (kilobit, not kilobyte) which will only work for short range communication (not much of a WiFi replacement lol).
In order to increase the range to the numbers you’ve talked about you have to reduce the speed to be 0.3kbps or slower.
At maximum speed at 1% duty cycle you’re limited by law and not allowed to transmit more than 2.376 megabytes per day.
There are less limitations on LoRa for HAMs in case the transmission is in one of the HAM bands (for example some LoRa chips use the 433Mhz band).
This case requires a license and has some other limitations.
For example encryption is not allowed as well as you’re required to transmit your call sign every time you start a transmission and every 10 minutes of transmission.
Yes, that is all true. Still pretty sure no one at all will concern themselves with any of that (Except the Ham guys who seem a bit obsessed over those kinds of laws and regulations) Nor is there any chance you'll be tracked down by suits walking around waving directional antennas all over looking for a Lora transmissions or a meshtastic relay on a hilltop some place. Even if they do go out, they do find it, they do take it, well... then for 26.00 I'll put up another one. No one is having their name and address silked onto these lora modules as far as I've heard.

The gov't learned long ago that they don't need to pay people to monitor this stuff, because neurotic losers will do it for free, purely out of conformity and spite. These guys literally have lingo to describe the practice of tracking down 'unlicensed' communications.
@@williamna5800 GFY! We'll pin your coax just like in the old CB days.
@@williamna5800 The thing is that Amatuer-Class licensees have ZERO issues self-policing unauthorized activity in their licensed spaces, ESPECIALLY when it comes to flooding and other forms of RF contamination. There are Official Observers (OOs) (and as of 2020, new Volunteer Monitors) who are HAMs that have been trained & authorized to file official reports of incidents. If it's bad enough, triangulating a signal is not hard, and these "Fox Hunts" are often done for fun at HAM Festivals, like a radio-based game of tag. Finding a rogue transmitter is just a sport to HAMs, so if someone is going to be a pest and hurt the community by DoS'ing the local RF bands, HAMs CAN and often WILL track them down. And they'll do it quickly because they think it's fun and a community service at the same time!

@@joetoney184 yep i knew that before i clicked on the video by the picture but didnt know it was gonna be so terrible
good intro... but for now what you said is just straight bullshit. LoRa is regulated to use different frequency in different part of the world, like 915MHz, 867MHz, 433MHz, and then there is the data rate, right now, LoRa theoretically top out at around 250kbps with 2.4GHz LoRa specification. You can't even watch your own video with that kind of bandwidth. You are misleading those people who don't have a strong background. In no world will LoRa replace WLAN. Then again, if your are already using 2.4GHz band, why not use Wifi then? It has way more bandwidth and crucially generally supported by most devices nowadays. If you would like to use on DIY project, why don't use a ESP32 then? It just as easy to use and it's way cheaper then LoRa modules.
You are a very smart guy and I did learn a lot from watching your other videos, but probably should have done more digging before making this video.
yes, typical youtuber i would say, A lot of bullshit and a very gullibe audience.ISM It is true that the 1280 can reach about 250kbps, therorical, but the range will be pretty shitty at this point, less than 1km with easy environement. With the 1262 at 868 or 915M it will be more like 25kbps, with 1% duty cycle max.
Well, tbf he did say you wouldn't be sending video or even images this way, but I didn't like the "what _they_ don't want you to know" BS aspect of it.
Every heard of SSTV, this is still a popular thing fifty years later.
I can think of one reason to use this over wifi despite the bandwidth difference. Okay, two. 1.) It's free, after its initial purchase that is. No service charges. 2.) It's decentralized. Hence the no service charges. But that's about the end of my limited knowledge of these. They're still neato. :) I'd like to get my paws on a couple for info purposed and general tinkering. Maybe you can tell me if these are suitable replacements for IR transmission generally found in the likes of radio-controlled gadgets like drones and RC cars or whatnot. I'm fairly green at this Arduino and esp32 stuff and there are soooo many possibilities out there that sometimes it takes a while even to correctly identify a controller module exactly as the IDE would know it to be when I buy a new, unfamiliar board. (It's been a blast, though. :) This rabbit hole is deep and super fun!)
@@NopeOnARope_ You can perfectly host a Wi-Fi hotspot at no charge and you are legally allowed to. You don't need an internet subscription at all. You could make a similar point with LoRaWAN, which is often a paid service.
The reasons why you would use LoRa in the 2.4GHz band would likely be range and battery use, since I expect that the LoRa modulation would be much more resilient than Wi-Fi, even at an apparently way lower transmission power. I've seen some experimentation that showed good results even indoors, which I really doubt would have been remotely feasible with Wi-Fi.
I actually recently researched the use of LoRa for RC cars. My opinion is that you can completely give up on using anything else than a 2.4GHz transceiver, because in sub-GHz you are too tight on bitrate, duty cycle limitations (PLEASE RESEARCH THOSE if you're planning on emitting at any high rate on sub-GHz bands, there is NO sub-GHz band you can legally use at such speeds without greatly reducing transmit power!) and the per-message overhead is too significant to make sense. And if you want telemetry, which is where using a custom radio makes sense in the first place, you're sort of screwed unless you drop the update Hz to sluggish levels.
LoRa and real-time communications mix poorly by design. Especially accounting to the fact that the LoRa preamble/header is a lot of overhead for very short messages. But I'm still actually exploring the 2.4GHz band for RC car uses for the meme.
For other RC stuff, especially autonomous RC vehicles, it makes a ton more sense because there actually seems to be a point to very long range low bitrate uses: updating waypoints, sending some return to home signal, receiving occasional GPS/accelerometer telemetry, idk I've never done drone/plane/boat RC stuff :)
These are amazing little modules, easy to use with simple Serial control and insane range. Using decent tuned DIY antennas they easily make 11 miles LOS so far.
As a side note: no reason for the "wifi killer?" thumbnail thing, kinda clickbaity for something that is in no way at all related to wifi. That's like showing a picture of a Ford Focus with "Learjet killer?" You can't really run to the corner store in a Jet and you can't drive a Focus across an ocean, why pretend to compare them?

I don't think so.
If you exceed the 0'1% duty cycle you can be fined a very-very-very expensive fine. (Up to 1 million euros.)
This technology is designed mainly for sensors and IOT devices. And I think it's awesome.
Surely you'd need an array of them esp. if it can't rx/tx simultaneously as uploader suggests.
This is only partly true, as the duty cycle is very dependent on the frequency plan. I've only checked both of the EU bands, but some channels in those allow up to 10% duty cycles at reasonably high transmit powers for some channels, and even 100% duty cycles on very specific channels albeit at a much reduced transmit power. Don't quote me on it though, I had to dig up ETSI documents that i probably don't fully comprehend :)
As for the 2.4GHz ISM band, for which there actually are LoRa transceivers, it basically just seems like a far west with no duty cycle limitations that is even harder to search legal info for.
Finding such information with limited prior knowledge was surprisingly difficult.
The thumbnail (and to some extent the title) is tiring clickbait. The comparison with Wi-Fi makes zero sense when you consider any conceivable usecase, unless you were using the wrong tool to start with.
@@OurSpaceshipEarth Most transceivers that I could find (that are meant to be used in end nodes, anyway) are indeed half-duplex only.

What is a "bowd" rate ?
Haha Was thinking that I'd been the one who has been saying baud(bɔːd) wrong! Weird hearing the term without being preceded by digits! (1200, 2400, 9600)
To be fair, Emile Baudot, after whom the term is named, would be pronounced roughly bow-doh in French, so consistent with his pronunciation of "baud". But yeah, it's almost universally pronounced more like how a Brit would pronounce "board".
@@PeteC62 weird, I've always heard it as "BOD" like body.

@edwardfletcher7790 I've always heard it as "BOD" like body. I had a BBS (Bulletin Board System - Pre-Internet) in 1986 at 1200 BAUD. I remember when I started using 2400 BAUD in 1990! Those were the days!
I spent several years in the Industrial controls industry and the company I worked for made hardware and software peripheral devices for Programmable Logic Controllers of different vendors. Our serially connected devices used the computer's serial port (9-pin or 25-pin) and, although versatile it was bound by the slowness of the UART (pronounced "You-art"). (UART stands for Universal Asynchronous Receiver Transmitter). The data rate of the UART is known as the Baud Rate (pronounced "bod rate"). Nobody in the industry (and I spoke with a LOT of engineers and systems integrators) ever called it the "boud rate". It's baud, rhymes with "Maud".

Back in 1960 I at 5 to 7 yrs old,was given a small device( radio) that you clamped onto a lampshade steel bracket( back when lampshades used a brass or steel shade bracket),or some peice of steel.it was able to pickup radio stations with no battery and worked on static electricity .
It had a volune control and staion changer,was the size of half a cigarette.
So called "crystal radios" were one the first types of radio receivers and pulled power from the broadcast signal itself. They connected to an earth ground and had a wire antenna, and a very small number of parts. The ones I've seen used a earphone and didn't have a volume control due to the low amount of power available, there was just a frequency adjustment to select the AM station. They did not work with FM.

Universal Asynchronous Reciever Transmitter, if my memory serves me.
LoRa is not entirely unregulated. You'll be in trouble if a single device is on over 1% duty cycle.
I am a little suspicious about the helix antenna, if it is a quarter wavelength antenna then it requires a groundplane to work properly, the groundplane creates an image of the field from the antenna. assuming that the groundplane is infinitely large, in reality the groundplane only has to be larger than the wavelength to do a decent job. I do think this antenna is optimized for size not antenna gain. Thus large improvements can be done. remember that the E / B field decays with the distance 1/r^2
My guess is its a 'hat' thing anchoring it to the ether, uses ground waves.
@joefish6091 the design of the PCB groundplane is important, the groundplane also radiates.

In chip datash*t. 😊
Just a heads up: "baud" does not rhyme with "cloud".
if he was from NYC woulod he say "fugataba-w-udit" :)
Its perfect for all those short burst covert messages that get sent so that big brother can’t track and intercept them.
exactly
You think the fcc is going to take down this video because they don’t want you talking about Lora? That’s just talk and you don’t think that.
Expanding on your idea, integrating multiple sensors such as weather stations, seismographs, and smoke detectors into a mesh network powered by solar panels offers a robust and cost-effective solution for monitoring and protecting large, remote areas. As previously mentioned, by expanding beyond a basic weather station, you can incorporate additional devices such as a seismographs or smoke detectors. These interconnected devices can be deployed in various remote locations such as forests, mountainous areas, or even pipelines. By utilizing a modest power supply and a small solar panel, these devices can operate continuously. Through a mesh network and a gateway connection, data can be transmitted to a central station in real-time, enabling the collection of data over a wide and protected area. This approach can streamline the hardware requirements, which would typically cost thousands of dollars, by developing applications for these compact and cost-effective devices. Ultimately, if a user is to enter one of this areas, he can have one device with simply a gps and 2 way audio that can cost around 90 usd that can be connected to the complete network and have you and the safety teams of your stats... just saying
great suggestion
"traditional terminal like bash" - haha, was using AT commands via a "terminal" before linux was born in '91
Love this video... having flash backs to the 80's, with acoustic couplers and basic programming - just like your doing now!
this is amazing!
Well ahctually.... Bash was released in 1989. Bash is older than Linux too.
@@DanielRisacher Yeah, UNIX has been around for a very long time.
@@DanielRisacher AT command set came out in the early 80's, originally designed by Hayes Microcomputer Products for their acoustic modems. It eventually became the de-facto standard of all acoustic modems.
The idea of installing remote weather stations with this tech is brilliant. I recently was introduced to a website called the Weather Underground, which is a network of community run weather stations. Someone in my area has one because there's no government station there, and the weather does differ substantially to the neighbouring stations, so we will be able to use it to monitor when to do certain tasks, like watering the garden.
But there are similarly exposed peaks to your Mt. Washington not far from there either. Mt. Bogong ... the tallest mountain in the state can have radically different weather to the trailheads for climbing it. A weather station transmitting using LORA would only need to have line of site with a server that's connected to the internet to handle this.
Genuinely a brilliant idea.
Yeah! Nothing like monitoring geo and topographical climate change in real time, like watching paint grow and grass dry
@@rawcado I'm not sure what your comment has to do with mine.
weather underground like 2 decades ago is how I learnt the short form of "Weather" for elitist weather nerds is "Wx", aka us cool ppl :). Sure was a great resource esp so long ago and prolly today for areas without overlapping gov/corp meteorological info like we get in cities..
Note that the word “baud” is pronounced the same way as “odd”, just adding a “b” at the start.
Kids these days. ;)
How helpful is it?
Wrong. Google it
When you use text-to-speech like this you really have to listen to the result and respell words that come out funky if spelled correctly. I'm guessing the creator used google translate to make the english version then fed the result into his text to speech program.
Why am I not creating videos in other languages like this? It wouldn't make me rich but it might earn lunch money.😆
No it isn't. It's.pronounced like fraud.
Is this a wireless relay? Is it communication protocol agnostic? Just it just trasparently trasfer from point a to point b wirelessly?
Hello from Ottawa, Ontario, Canada eh! Sir, I respectfully suggest that you consider that there are many experts who will flame you for not fact checking everything you say before publishing your videos. Some will go as far as your spelling. Some will be disrespectful and not treat you the way they would want to be treated. Others will take your transcript and run it through an AI to scrutinise absolutely every claim you post as facts. Please be careful, but do indeed continue helping others. Both you and your subscribers will all benefit in the fantastic journey of acquiring knowledge and discovering what is true and what is a lie. I salute you Sir and wish you and your loved one well. Have a good day eh!
Well said
What are you doing online? Insult him! What are you? A commie? ❤❤😂😂😂😊
Would love to see more comments like this one
Cringe.
Great for IoT, concerning for IED 😬😬😬
0:55 bruh. That line it's like "the miracle recepie that doctors don't want you to know about" type of bs 🙄
Using the attention (AT) commands to run communication brought me back to 80s/90s terminals!
Same here!
baud is pronounced like "bod" as in "dad bod". Not Bowd.
Well, that's the Anglified sound, but the guy was French so you have to pronounce it in French: Baudot,
which is definitely not 'bod' or 'bowd'. Can't help it that English doesn't have an 'au' sound.
That is also incorrect. The phonetic spelling of baud is bawd. Bod has a significantly different sound.
You can achieve the same with Bluetooth, but not WiFi. Actually I managed to get over 10 miles range with Bluetooth. This is how it works: As you increase the bandwidth, or the amount of frequencies required to transmit something the shorter the range becomes. It uses more energy to spread the radio energy over more frequencies. The less frequencies / bandwidth you use the more energy goes into each frequency. Therefore narrow band has much longer range at the same transmit power level that goes into the antenna, callsed EIRP. Now further you can use a helical monopole antenna like they did which has a higher gain on the horizontal plane if held vertically. If you uncoil it the gain will increase. Directional antennas like planar, yagi and so on can achive 15 dbi or more gain. This means that you will achieve 6x to 8x the range. Using correct antennas, correct bandwidth, correct coupling, grounding, etc you can make RF do magic. Looking for RF advice, there are many resources online. Be careful though it is very easy to have 1 thing wrong and get 1/100 of the range that you otherwise could get. It is because signal propagation is exponential. You must get it right.
Teach my your ways...
first title was phone company killer now its a wifi slayer lol JERRRRY !!!
In it's heyday, traditional Internet phone modems were 56k (56,000 baud rate). This is roughly twice as fast and can be faster utilizing compression.Only the protocols and translation overhead, and possible security protocols must be accounted for. Analogous to early DSL, ISDN. So a wireless phone modem technology. An enterprising group can build a decent communication system over this that can include audio and video with compression. I like it.
would nee4d an array of em and encryption due to 1% duty cycle regulation.
i think you missed that when he set the 115200 baud rate, that was only the bit rate for the USB to UART bridge. at 8:50 to 8:54 he said LoRa is meant for about a hundred bytes every 10 to 15 minutes, which is a much lower data rate. and wireless data transmission rate depends on other factors, like the LoRa module settings, distance between nodes, interference. but generally the point of LoRa is in the name, Long Range. and to get the long range it means a lower data rate
lol internet phone's? at 56k? funny, I though they came out AFTER the INTERNET........ giving the net in 1980 was 4 websites... and none of them offered phone's
My Fastweb mobile connection is rarely above 10kb/s so I think this sounds promising ;-) My Vodafone FWA station provides 1kb/s at this very moment. So consider how these giants slow us down .....
@@HarmonRAB-hp4nkThere were exactly zero websites in 1980: the web was invented in 1989.
Is it really possible to trust somebody who doesn’t know what the nail file on the clippers is for?
i was watering at BAwUD and youee=eheart for AURT
Nice video! For future reference:
UART -> pronounced "yoo-art", letter "U" then "art"
Baud -> pronounced "bod" like part of body
This is standard pronunciation in the engineering community in the US.
Dude, you're killing me. It's pronounced "bod", not "bowed". Sincerely, someone old enough to deal with 300 baud modems.
Lol, me back in the day....
I remember back in the day when modems were measured in bauds some made the joke of saying it that way or a play off tge word body or bods. Its kinda like schedule (sked jule) and schedule (she jule) both are correct..and yes i notice the phonics suck
Baudot is pronounced boh-doh, so technically.., Yes, I remember paper tape unfortunately.
That is also incorrect. The phonetic spelling of baud is bawd. Bod has a significantly different sound.
Very cool video! Thank you for making it. I have been interested lately in LoRa stuff and your very basic introduction was a breath of fresh air compared to a lot of what I have seen lately.
I'm an old guy: I've been doing computing since early 1970s. That's back when we had to carve our 1s and 0s outta stone.
UART is pronounced "you-art".
BAUD is pronounced "bawd".
I was exactly like you in my youthful days. I spent my hours reading and learning and working on ideas with boundless enthusiasm. Talk to some folks and you'll learn things like these pronunciations and it's also a great way to share what you know. RUclips is, of course, also great for that.
Awesome video! One question is this is a Transceiver can this be used to analyze and capture wifi data packets to try and figure out whats going on with a wifi project im working on? I dont know that much im just getting started with more complex tasks with my RPi4!!
Like how could i use this to see the wifi information or packets being sent between devices, when theyre using a 5.8GHZ Wifi protocol from everything i can find about it?
Or what would be a cool project to make to use these in?
Absolutely not, they're completely different. You're just asking for Wireshark, and if you need something lower-level, I don't think there is much consumer-tier hardware to save you.
@@asuasuasu I'm trying to capture the WiFi video used on my digital VTX from my RC airplane with an FPV camera on it.. The WIFI signal is 5.8ghz and i can select where in the Band more specifically using the CH's. 1 thru 8. Which are just spaced out so other people can fly with you..
However as far as i know the WiFi signal is going directly from the MIPI camera to the Digital Video Transmitter over WiFi (encrypted i think) and straight to the Goggles which have 5.8ghz LHCP Antennas on it for the Video Receiver (VRX) and then out to the Googles Display screen..
However there's no way right now to let other people watch what you see in the goggles except with a small phone screen over USB-C from the Goggles in a very low resolution..
We were trying to make a VRX that we can hook up to a screen. Then eventually try and downsize and build into a portable monitor setup for spectators (and spotters) basically..
Any ideas on what i should research and try first using Wireshark and maybe any other programs? Would any devices be useful for this like a flipper zero or is that not really useful for this?
If I'm only using Ethernet on my PC for the Internet.. Can i use my current WiFi-6 Card for WireShark, or do I need something special for this kind of work?
@@mxracingunlimitedltd7784 Sorry, my knowledge of Wi-Fi is rather limited here. I don't really know if your usecase is actually using the Wi-Fi protocol (as opposed to just a custom radio that happens to use the same frequency band), and if it involves a regular access point that regular devices can connect to. You'd probably want to first dig up details on how exactly it works if anybody has done the work.
As for wireshark, some chipsets/OSes may have different limitations with regards to listening to packets while not connected to an access point but I don't recall the specifics (especially in modern Wi-Fi).
All hail Channel Blocker extension so you do not have to visit channels like this ever again!
😅
Does this have the latency and/or reliability to beat starlink in any use cases?
It's baud pronounced like bod. The work baud comes from Baudot en.wikipedia.org/wiki/Baudot_code. It was shortened to just the first syllable in common usage.
Exactly! Thank you! I've always heard it as "BOD" like body. I had a BBS (Bulletin Board System - Pre-Internet) in 1986 at 1200 BAUD. I remember when I started using 2400 BAUD in 1990! Those were the days!
dunno what the hell you think this baud is but uh.... not we call its BITS........LOL idiots its a simple measurement of bits per second parsed into bits since they didnt have anything capapble of bits per second
That is also incorrect. The phonetic spelling of baud is bawd. Bod has a significantly different sound.
@@arxmechanica-robotics I think your splitting hairs here. I think the differences you're pointing out can be attributed to regional accent. Northeast vs. South for instance.
@@dougcox835 one is correct. The other isn't.
Can we put it on the FPV drone?
As soon as he said the the module was capable of sending "over 12 miles" and "this video may not be up for long" I lost any faith in his legitimacy and stopped watching... That antenna's not going far and the conspiracy theory is banal. I'm not going to waste my time on such stupid and misleading clickbait...
Bye! ✌️ Don't let the door hit ya.
Don’t forget it broadcasts peace and love, lol what a joke
Sorry to bust your bubble but as a guy who has been into radio for 19 years now, I can tell you that we have used LORA at altitude and gotten 10 miles out of it so it is possible.
I have used these chips. They worked for under 2 miles in a rural area. I consider that pretty good. But it is not WiFi killer. You can only send short messages over long range. Good enough for switching devices remotely but not much else. Thank you.
Our local farmer had a system installed to run automation around the farm( around here it's a flat as a kippers dick,so in theory they had half a chance) It was promised to be capable of sending small data packages for irrigation and location systems,turn on pumps,valves etc. Noticing it being all being removed about a month after it was fitted I I took the opportunity in the pub that night to grill the the farmers son who incidentally is a fibre optics engineer. He stated that it just didn't work,its limited capacity wasn't capable of controlling some of the devices dependant upon it,it had poor and varying signal performance,was apparently susceptible to interference and easy to intercept/interfere with,admittedly the last not really a problem for a farm.but I'd imagine the farmer still expected it to at least work. Upon further conversations,their new set up is a Motorola system that was in his words "not much dearer but leagues ahead in performance". much like anything,if these cheap little devices were as good as stated their use would be widespread.
Data trooper is a massive thing you have to consider because you can’t just replace Wi-Fi with this and connect 100 clients with no problems
Can you use this in small commercial drones to get extra range?
For your distance testing, would it be beneficial to set up a ping and return, rather than only counting, so latency and dropped message ratio can be visualized?
Also, I missed how two or more nodes which have the same address and frequency would be differentiated.
good question, unlike the rest of these plebs omg this place is a dungeon
Just bought a pair of cheapo ones, I'm a ham radio nerd so I'm going to try to adapt a SMA port instead of the coil antenna and put a dipole up on a 10 foot pole and see how far I can reach it.
Report back any findings
'Yes. Can you order a pizza for me?
12 miles away; 😂
NOTE: It's just slow serial data. Essentially, it's just a wireless rs232 link. Which is the oldest and slovest serial link u can get. A few kbs at best. For wifi, we're talking mbps, or even gbps.
So don't mistake this with wifi or 4g 5g or anything fast.
Very interesting. Can I connect it to laptop or tablet to extend the capacity to connect to my internal home wifi? Can we call this device a wifi booster?
would it be possible to route internet to one device then use lora to link it to another device and make a wireless access point elsewhere? i just got a couple of these to try this project because i got a spot where wifi cant reach.
Cool LoRa module.. Thanks for sharing!
PRO TIPS:
-Baud is pronounces bawd.
-UART is pronounced "you art". (not u-a-r-t.)
Thank you for the video and all the information!
I could see the usefulness in this. Even though the baud rate is pretty low, you could still use it for flying UAV’s (remote control aircraft) long distance and still have plenty of room for long distance point to point missions. As long as the aerial vehicle is within line of sight (as directed by the FAA) and it’s not flying in controlled airspace (pilot will need to use a NOTAM for flight planning). I’m not even sure if I said that right. If there are any pilots out there who are willing to correct me, then please feel free to do so. I’m wanting to study for the part 107 exam so I can fly drones commercially and get paid for doing so. If anyone has any great tips, again, let me know.
One use case for this is in the mining industry; which is connected machinary like pumps and motors to monitor them remotely.
Can they be used like a repeater, with a series of them?
Why did you twist the wires up when connecting to the usb adapter? Just flip the 4wires, yorb to broy
Another reason you may have rx in the parking garage is radio reflection off a near by structure. I will have to check this out I have several potential applications I may be able to adapt to this. Thanks.
Yes the problem of those devices are that there are limits to their allotted data rates per time period. The way they seem to work is basically they set up an in line serial connection, which I guess you could use like modem point to point protocol at probably a horrible rate to literally get the internet. I was thinking of the IDEA, not even really starting, of how I could get internet from my parents where they are like 25 km away. All in all there is not a great way of doing it. I guess if there was a high point I could shoot 2 invisible lasers at a building and look for the other spot on the building for their signal. There is no socially nice way to do it. Today I just have a 110GB cell plan that costs about $110 Canadian a year.
Is the cell phone reception good at your location? If the reception is good then you probably have the best option atm. Cell phone towers have backup power during any electric outages which is a plus. However if your signal is bad, then you might consider a starlink system. The base price is $120 dollars per month unlimited data. The only catch is it does perform worse in stormy weather conditions. Average speed for canadian users are around 100 Mbps down and about 15 Mbps upload.
Ppl; have beamed wifi rf line of sight towers out over 100 miles. you can manually adjust antenna til best signal
Seeing magsik logo after so many years, brought back so many memories
Do u have online store to sell pre-build end product?
Haha the first 2 minutes sounded like those scam sites talking about 2 brothers who are disrupting a billion dollar market.
Tx is usually short for Transmit and Rx is short for Recieve in most radiofrequency tech ...
17:34 - It was reflecting off the buildings around you, of which there are plenty.
I am a little confused by the range test. If it was going thru wifi then the range did not matter because the signal you received on your phone came thru via the phone towers near you and had nothing to do with the range of the Tx. I understand radio but still I may be mixing stuff since I dont know much in this field.
C'mon 8:52 "LoRa technology is designed for... sending around 100 BYTES every 10 to 15 MINUTES"
Biggest problem is when everyone within 12 miles has one in a place like New York city with all the skyscrapers. We could have 1,000,000 people trying to send messages all at once. It would be all lag and messages colliding. Making the device useless. WIFI has limed number of channels. That's another reason why WIFI has limited range. If WIFI had a mile range it would also be unusable.
I wonder if the rebar in the concrete works as a antenna.
I agree with many commenters that the title of this is a bit click-baity, but the video otherwise does a very great job of introducing and displaying the capabilities of LoRa. It also gives enough information for creating a basic implementation. My son and I used this video to get LoRa working as part of a school science fair project, thanks to this video. Meanwhile, I am going to ask a technical question for any power users of the RYLR998, or similar devices....
As in the video, in a serial terminal, when connected directly to the RYLR998, I can get the UID using AT+UID?
I need to query for this UID from WITHIN my Arduino application, and assign it to a variable, so that the UID can be forwarded to the receiving LoRa radio for unique source identification. Any pointers on how to format this code? Much appreciated!
AT+ADDRESS is prob what you want, I'd use python or some such scripting language
That is amazing to be able to send/receive data several miles using only a few hundredths of a watt. Maybe extend range with obstacles with an RF amplifier if you can sacrifice the power.
You put these on street lights a few miles apart and create a giant webbed mesh communications grid.
Hello from Ukraine, can I use it with FPV drones? And how sensitive is it to active radio frequency jammers?
Correct me of I'm wrong, we have been sending low frequency long range data for over a century now
This is very helpful information,thanks very much.
Definitly a safety factor that will pay dividends,you are on the right track with this idea.
I want to setup some thermo sensors in some out buildings to read and report temperatures every 30 min or so. This might be perfect to use with an RPi Pico and a temp sensor to send data for computer collection by a daemon/server, display on a web page, and send alerts to me if thresholds are passed. It is key for low power, long range small payload data comms but it ain't replacing WiFi.
It needs clear field without obsticls otherwise its range is limited to one or two kms.
cool device, i was wondering if it would work for my system to maybe increase my devices connection?
i am currently using a samsung s8 as my mobile hotspot, connected via the USB for USB tethering into a PC. is there a way to open the phone and add the system to it to increase the range or strength of my data connection? i dont mind modding a bit and 3d printing a new case for it.
And it has the fun appeal of QRP., solar powered, parasitic RF ie crystal radio powered etc. (fond memories of LM3909 etc)
I'm now in trouble with industry giants, thanks man
You too, no worries I'll have my people call those giants and sort ya, hopefully he's got something uploaded on these giants or I fear I've overcommitted here... Okay chatGPT suggested basic giant speak, like "no FEE, also no wiFI, user not FOE, FUM". fum to terminate like NL,CR chars terminate Lora AT commands. :P
Using a RF Pineapple and DragonOS ...these are very easy to compromise by simply scanning bands or skyjacking frequencies...these need a more secure way to transmit data especially if one is sendinf locations and times. Awesome video and really amazing little device however, thanks.
