Arduino meets RYLR998: A Comprehensive Guide to LoRa Module Integration
HTML-код
- Опубликовано: 27 май 2022
- Company REYAX provided me with two Lora modules (RYLR998) to play with and to create a video about them.
In this tutorail I will show you how to program those radio modules. How to connect them to Arduino. I will also create the code that will allow to remotely control the state of LED with the pushbutton.
Hope you will find this video Useful.
You can find more information bout those modules on the Manufacturer's webside:

very GUD
Great video.
THX. Give the video a like. Helps for the video to get noticed
Very Good
Thanks. Give video a like if you enjoyed it:)
You should probably make the Arduino configure the LoRa module in the setup function, that's much easier to maintain.
Thank you
A 2 Z Thank You....!!!
Bardzo ciekawy odcinek i fajny kanał, pozdrawiam.
Dzięki:)
Excellent video!!!
There seems to be a long lag between pushing the button on the transmitter and the LED ON/OFF state.
Is this due to the code used or normal delay to expect with this LoRa device?
Thanks, that’s some explaining done right.
One question, can we use those module to create mesh network with them, where the network can discover and new nodes in the nwtwork (auto-configuring network)
I am not sure. Please check at Rezax. They usually provide good documentation.
That's a really cool project. Could you make something similar with controlling relays instead of the LED? I can't find anything really basic as far as a tutorial goes to set it up. Any books you can recommend for learning LoRa and things that you made for this? thanks
There is virtually no difference. You send the high signal to Arduino pin to light up the led and in the same way you send high signal to relay to control whatever the relay is connected to. As far as using relays is concerned you can check my other tutorial ruclips.net/video/XiOcxyyTxy4/видео.html
@@marios_ideas thanks I'll check it out. Appreciate it
@@woolfy02 My arduino IDE not detecting says unknown board and serial monitor does not work
Very informative video. I really appreciate it! For both REYAX RYLR896 and the RYLR998 modules, I saw one review on Amazon, stating that the person would get them to work and then they would fail. Have you done any longer term testing to confirm the stability/reliability of these modules?
Unfortunately I did not. I have a project in pipe to use them which would answer youer question but it will be a while before I will do it:(
@@marios_ideas Thank for answering. I'll probably buy a couple of them and set up something in a couple of weeks to test reliability.
What is the max range of these modules? Excellent video, thank you!
well. Thats what I want to check in the residential area.The datasheetdoes not give hat info. But other tutorials say 10km+. If you enjoyed the video give it a like

I have RYLR998, when set band using At command "AT+BAND=865000000", it remember only when it is connected, when i disconnect and connect and ise "AT+BAND?"
it shows +BAND=915000000Hz, why it is not remembering BAND?
managed to solve? i have this problem too :C
@@teusocost No, now each time I set band
Answer AT+BAND=865000000,m write toe memory. RTF !!!
Can't you use an arduino board with 5v just by limiting it with resistors?
Where do you get the jumpers? What are the lengths available? What is the wire gauge size required?
Amazon has jumpers galore...
It's a piece of wire, small gauge, it's from one hole to another, it's not brain surgery. Improvise. Did you ever have a 151 Electronic Project Kit from Radio Shack as a kid?
Dear sir, do you have an implementation with mesh net with RYLR998 and ESP32, would you give me a sight, please.
I'm looking to use this module with my Flipper Zero.
There's a LoRa app built into the Flipper Zero where you can set the parameters as you did in this video.
On the other end, I don't have a 2nd Flipper Zero though so it has to be my laptop it's communicating to/from.
I have a uart to hook up the laptop to the LoRa module. Do I just open the Com port & start entering the parameters this way?
I'm NOT looking to light up an LED etc. I'm simply looking to both transmit & receive to both the LoRa modules texts.
Do I just set the parameters in the Com port & then I'm good to go?
So to reiterate, the parameters will be set in the Flipper Zero & using jumper cables. The LoRa module will be connected to & powered by the Flipper Zero. It can send/receive through the LoRa module.
I need to set the other LoRa module up to my laptop. Is the LoRa module good to go without writing code & just setting the parameters up through the Com port?
Have you find an answer? I am looking for setting lora without UART
Can you send the link to buy it saying the is stock available? Amazon does not have, Aliexpress does no have, etc.
I found this one www.ebay.pl/itm/326090697862?chn=ps&norover=1&mkevt=1&mkrid=4908-166454-595607-3&mkcid=2&itemid=326090697862&targetid=293946777986&device=c&mktype=pla&googleloc=1011615&poi=&campaignid=20217678640&mkgroupid=148313024046&rlsatarget=pla-293946777986&abcId=&merchantid=694404522&gad_source=1&gclid=Cj0KCQjwxeyxBhC7ARIsAC7dS3-FLp2j3wbtJnnRDYNhgfWtBOzRFKgMqIed--6W_RUF11YN9GohXxYaAlDoEALw_wcB
Which terminal program are you using? It looks like Arduino but I am not aware of how you get that interface to come up?
It is Arduino IDE. When you open it you will find serial monitor icon in the top right corner which opens Serial Monitor
Can I use the lora module with the seedstudio ESP32 C3 module ?
Did not work with that microcontroller. But I checkt and it has the UART interface and works with 3,3V logic. So I do not se why it would not work. I am not sure if it is supported in Arduino IDE , though
This is a cool project using Arduino, how about if I want to design it using other AVR chipsets. It is easy to prototype using Arduino board. However, with my entrepreneur hat on (idea lead to production product), I do not want all the functionality of an Arduino board, I just want a voltage regulator with a 3.3vDC, external crystal of my liking e.g. 7.327Mhz (for UART)..a serial port on Port B to load my program in, LoRa module and a selection of AVR microcontrollers e.g. ATTiny88 or ATMega164PA to choose from (to reduce cost) etc.... Any recommendation?
I am probably not the right person to answer it. At least not now. I will be doing future videos on ATTiny chip but I learn as I go. You probably want to ask this at Arduino forum. I presume that as long as the chip is 3 v and provides serial com ports this should work the same. If the chip is in 5v logic you need to have Logil Level Converter. Funny enough I am planning to make a video on such converters in coming weeks as well:)
Have you been able to test its range? Is it correct that its range is more than 10 km?
I did not. I know that I promised to. But I was caught by winter and it was too cold to do it. As soon as it is warmer I will create a short video to give it a test.
How long range distance if we use that module?
The manufacturer days with tweaking the parameters the range can be to up to 10km. I am yet to do a test in Urban area but i think 3-5 km schould be possible
I have a problem with setting the parameters, while the module is connected everything can be configured correctly, however when I remove power from the module it returns to the factory settings, what should I do to solve this?
I can't relly hrlp you as my modules keep the settings. But you are a second person reporting this to me.
Are you asking for a solution to a problem where, in a 1-to-3 communication scenario, even though the same network ID is set, when a value is sent to address 1, values from address 2 are received, but values from addresses 3 and 4 are not received? In other words, values from one side are not being received. Is that correct?
I am not sure which problem you are reffereing two. Can you refer to the timestamp in my video?
I ran across this video recently and wanted to check the code, but the link to the code is broken. help me out here Mario!
I added an extra link. Consider supporting my channel.
Mario, can you please help me with a very simple looking problem? I have 2 boards, just like you. At the transmitter board I have a loop with 2 send lines. There is 1 second between the transmission of the lines.
The transmitter runs ok. I got the +OK after the send lines are executed. But the receiver shows only the first received line. I looked with a logic analyzer and I see the 2 lines are transmitted. But on the receiving module there is no reception of the lines after just the first. It looks like the receiver is no longer in receiving mode.
I swapped the boards. Same problem.
What happens if you make the delay longer In my ideo you have seen that I was sending led state few seconds apart without problem.. Also try to run transmission 1 twice to see if maybe there is some problem with the content of second transmission. Diffiult to troubleshoot without hands on the prototype:)
Hi Mario, I got it working. I first did an AT+FACTORY and only changed the address of the transmitter and receiver. But there is still one problem left.
In about 20 transmissions of a 5 character string one of them does not come out of the receiver. It was transmitted with an +OK response. I lowered the baudrate to 9600.
Same problem…. This will become a very difficult problem to troubleshoot I believe.
what about range?
I want to make the video for range testing. But i need to design a proper design. I will not be going around with breadboard and dupont jumper wires. So I will create it but it is not going to me next week:*
Is there any possibility to configure lora without UART, maybe with arduino directly?
You can issue AT command from Arduino sketch so you can configure it from within the code
@@marios_ideas Thank you!
