At the time of posting, this video is 100% correct for v3.2.x…. BUT, in v3.3 which is currently in release candidate, the bind phrase workflow has been “fixed” so that wherever you last set it from (configurator, webui etc.) will take priority. This means you don’t need that last step to set the bind via webUI anymore.
@@JoshuaBardwell and this is EXACTLY why I dont mess with elrs. if I blink I am out of date. Xfire just works. a how to bind a Xfire RX video would be 34 seconds.
I really wanna love ELRS. I really really do. Took me a day for my spi whoop to flash and bind. I have 2 more built but grounded till I can recreate that winning lotto combo. Then there is agent X, M, and FU, I just wanna fly. Wish I could plug the quad into the radio, run a lua from radio to flash and bind all in one go.
Wow!!! That is so much easier than using Crossfire and hitting 2 bind buttons (at very most). PS, nicely added filler to get past that 10 min mark. I really need to try Expresslrs sometime so I'm able to say from experience that it's just not worth all the hoop jumping when you have the ease and great performance of Crossfire. The range and penetration of Expresslrs is going to have to mind blowing for me to go through all that crap just to establish a link..... Still love and appreciate all your help Bardwell.
I never add filler content to manipulate length and run mid-rolls. My videos are as long as they are. And anyway, the cutoff is 8 minutes not 10 minutes, so do with that whatever you want. From the tone of your message, it sounds like you like Crossfire and are not sincerely interested in the things that ELRS brings to the table. Dont' bother trying ELRS would be my advice. It will be a waste of your time, and will just self-reinforce the things you already believe. In case you are curious, the reason ELRS doesn't have over-the-air firmware update like Crossfire is because ELRS is supported by many different manufacturers. Because there are so many different firmware targets, they can't all be stored on the module and automatically flashed at bind time. The tradeoff here is that you can always find ELRS in stock, and there is cross-vendor competition for features, build quality, and price.
@@JoshuaBardwell I am interested in the penetration ELRS is said to have over Crossfire. You have to admit with ELRS there is a lot more you have to go through to set it up and especially your first time setting up the TX as well. I kind of look at it the same way as I look at KISS Ultra. A completely different and seemingly more complicated animal than Betaflight. Your opinion on both has me decided that I will try both in the near future but the set-up process on both is what's holding me back. I rarely have any range issue with my Crossfire and I'm not a long-range guy anyway. I'm interested in if the penetration with ELRS is that much better than Crossfire? Is the juice worth the squeeze? 👍
If you're using 2.4 GHz ELRS, compared to 900 MHz Crossfire, then which one has more range is difficult to predict. Crossfire's lower frequency will tend to give it longer range, and I suspect it would win at 50 Hz, but lose at 150 Hz, since 150 Hz CRSF doesn't use LoRa. If you're comparing 900 MHz ELRS to 900 MHz Crossfire, then ELRS will give better range. When both are operating at 50 Hz, ELRS will give somewhat better range because it has a smaller, more efficient packet format. This allows it to use a lower bit-rate modulation that has better sensitivity. ELRS 900 MHz can also run at 25 Hz, which would further increase its range advantage. CRSF 900 MHz can only use LoRa at 50 Hz packet rate. At 150 Hz, it uses FSK modulation, which has significantly shorter range. ELRS 900 MHz can go up to 200 Hz packet rate using LoRa. At 200 Hz, ELRS 900 MHz may have less range than CRSF at 50 Hz, but CRSF doesn't even offer this option, so it's worth calling out. In general, I would not expect ELRS to have enough of a range advantage compared to CRSF, to make it worth switching, as long as you are okay with the 50 Hz packet rate. If you want lower latency than the 50 Hz packet rate offers, then ELRS is worth switching to.
@@JoshuaBardwell what about penetration in your opinion? I park freestyle (trees interference) and some bando/around buildings freestyle (concrete interference). How would you say the penetration compares between Crossfire and ELRS? While I have you in the comments I also am curious to know if I can get better range and pentration with my 03 air unit. I have Integras in fcc mode and lose video at lower altitude long before a lose my link quality.
I can't get enough of your vids!!! They are so helpful, and I always love watching you!! Keep up the amazing work you are really improving the hobby for so many people.
Don't know for sure but there may be some steps missing involving swapping wifi connections since your system is setup with two of them but most people only have one. Frankly I got a bit lost after you did the download and build of the firmware. Probably nothing I couldn't sort out when doing it for real but just saying I didn't come away with a strong confidence that I understood all the steps and order of them to do the job, which by the way is not normal for your channel, i.e. you are the best that I know of at providing easy to understand detailed steps for getting whatever task is the subject of a particular video if that makes any sense. Cheers!!
I am learning to new to this new hobby and Joshua you been really helpful. All of you guys and FPV community have been great, anyways still can't bind my Mobula 8 to my Elrs boxer. Right now, I can only connect to betaflight through virtual option and can't access my presets I think I lost it because I can see it when I try to ready the codes through my pc.
Your humbleness is crazy, And I plan on joining your Patreon soon also I have watch all three elrs videos this time it's just with my actual radio and my first radio.
@@JoshuaBardwell Awesome. Thanks so much. You’re a big help and the reason I can maintain my sanity in this sometimes confusing hobby. I’m joining your patreon now.
7:38 even tho you didn't show your binding phrase you shoved your uid (unique identificatior) what if someone types that into rx tx they can basicaly controll your stuff, i think you can blur it somevere in yt studio, great video about elrs JB have a great day
I have crossfire and don't need elrs. when radiomaster stops messing around and releases a boxer max I will buy that and probably watch one or maybe even 2 of your many many ELRS videos. jeeze. :)
I got 3 elrs nano and mico modules and 9 rx's . One worked until jb weld doesnt stick the tee antenna to carbon fiber and it shredded in the props . Could not fix the ufl connector . All nine said factory firmware matched but doesnt . Buy a computer and cable anyone ? I learned my lesson . Chasing a more and more expensive carrot no sir every week upgrade videos
so If I do not want to flash the firmware, but just want the advantages of having a binding phrase, can I just enter the binding phrase in the 10.0.0.1 web page and save it to the drone and radio that way? [your video at 7:40].
I can not figure out how to install my rp3 reciever in my drone. Ive soldered everything correctly and I made sure there were no shorts. I turn it on and the reciever just flashes for a split second and then nothing happens. Do I have to give it power before I solder the TX and RX wires or what am I doing wrong?
Awesome video. You are awesome! However, as a software developer for 30 years, I find this to be the worst design for software firmware updates I’ve ever seen. And you have some how found a way to make this work for us. Thank you!!
I have never had this much trouble BINDING a transmitter! I have been trying to Bind my RadioMaster Ranger ELRS with my new Chimera7 Drone for the last 2 1/2 hours with no luck (So FRUSTRATING)... Until this 10 minute video!!! Thank you, thank you, thank you! (I wish there was a way to send you $20 on here!)
Watched this video till the spi internal aio whoop not the same instructions part. 5:30 😢 I'm having trouble binding multiple betafpv spi whoop boards with my elrs tx. Some will bind after hitting the bind button in betaflight others go into bind mode but don't ever bind. I only have about 4 and got 2 to bind so far and I didn't use a bind phrase I just pushed bind on both rx and tx and boom they were connected. But is it really connected? I kept getting what seemed to be like failsafes during simple flights around my house with one board. 🙃 honestly I thought I was switch from tbs crsf to this to not only save money but to have something that works consistently and efficiently but I've spent all night trying to use the configurator to bind/flash the rx / tx and kept coming up with failures. I've given up for now😅 i did buy some normal elrs rx's so ill come back to this once ive mastered the spi based internal rx's first...
I been watching your videos for a while bit you hit the nail on the head in this one when you said I just want to bind and fly.lmao I did watch the long video to first tho and I'm still lost so I will have to watch it again and probably again. Thanks Mr.Bardwell your the coolest! TwistedFPV
im glad im not the only one actually following both n still 100% stuck - i love the guy too but this is the 3rd Bardwell video that 0% works - did u ever get this to work if so how??
Thank you Joshua you have saved me from spending days on getting my gear running, but I have an issue with a Zorro ELRS TX, it is bound to the RX as it says on the radio when I remove the battery from the RX and when I reconnect the battery it says connected again, on BF I can see that the Roll, Pitch, Yaw and Throttle work but not the switches. I have tried everything but nothing else works. dont know what else todo.. or what direction you can point me. Thank you !!!
My procedure is to connect to the receiver with WiFi and set it to connect to my home network. Then I build and flash from the configurator. This has worked for every receiver brand except the Axis Flying receivers I have. With those, WiFi did not work correctly until I had upgraded once. After that I am able to use the same method with home network set for future updates.
you can also use your phone to check the firmware version instead of having 2 wifi adapters and switching back and forth between networks on your desktop
I had a surprisingly smooth experience with elrs spi binding on a mobula6. It wasn't binding probably because the elrs came from factory with erls firmware 2.x I flashed betaflight 4.4.2, went to the receiver tab, selected SPI and entered my passphrase.... thats it, no wifi needed, no compiling, no need to do anything on the Transmitter.
I am so new to ELRS, I'm still itching from my shrink wrap!....I still haven't attempted to set up my first ELRS micro racing drone, being an airplane guy, thus wanting the security of ELRS. Anyway, you do not mention with new receivers of "any" type, placing the LUA script of it into the Tx card tools file. Betafpv, where I got their micro PWM receiver, states to do this. So, do you?
Hey, I have Cinerace20 and I cannot connect with Wifi. Its flashing fast but I do not see it on any device. Radiomaster works good bit Cinarace is not visible and cannot connect:( do you know what is it?
I've flashed ELRS receivers various ways, WiFi, Betaflight passthru and a USB/TTL bridge. Whilst the WiFi approach specified here is undoubtedly very convenient, one thing I've found one needs to watch out for is WiFi range - the tx power from the receiver seems very low. Move the PC antenna and Rx too far apart and it'll lose connection pretty quickly - mine does anyway. It hasn't happened to me yet, but I wonder what might be the result if it lost connection in the middle of flashing. Don't know but suspect one might have to force the Rx into boot mode and reflash with a USB/TTL bridge. Important to make sure the WiFi connection is solid, anyway.
When I try to import the new firmware to the receiver, before it can say update complete, the receiver switches back into its initial binding sequence and disconnects from my computers wifi. Im not sure if the issue is my soldering or what, because everything else seems to be working so far... any would be much appreciated.
Hey Joshua I don’t know if you will get this question or not I just got my radiomaster pocket and my baby ape 2 pro and every time I try to flash I keep getting a build error code in express Lrs configurator do you have any idea why ? I’m about to give up any help would be great thank you so much.
This is great was following your perfect build just waiting on motors but I couldn't set my mind to a receiver because I don't have a computer at the moment can you use the app it has a elrs section will that work
I just bought the geprecdark star 20 and y cannot flash it. When i tried to do it trough wifi mode, it appears that the receiver is beta fpv 2.4 nano. I dont know what firmware set up, if it is elsr beta 2.4 nano or geprec 2.4 nano as the manual said. What do you suggest?
Will a rx light up if plugged by usb only? I don't have the power lead soldered yet onto the fc aio. But I wanted to c if I can update or check the elrs rx via usb power only.
is it okay to update a bind and fly receiver ? I don’t want to risk messing up the settings. at same time I am not too familiar with fpv and trying to get flying soon!
I put all mine to connect to house wifi to use my computer (my wifi burntout on it) but now I can't update outside house. Thinking switching back to 10.0.01
Hi Joshua again!! Please tell me the distance for the ER4? I like this for the small floater planes The radio will select the output for the TX but how far can the ER4 go? Please tell me
Hi Joshua, I have a question no one answers......... Can you change your "pass phrase"? My friend put ELRS on my TX16s, upgraded it to EDGE but I want to change the pass phrase for the ELRS modgule Can you tell us how, I would really appreachate it
hi i have a zorro 4 in 1 radio i notice that the relrs adio master has an express module do you have a video that shows how to change the 4 in 1 module to an elrs??
I was wondering if you would be so kind to give me the link where you mention the partition file to be installed in the TX module when one have a tx that is still in 2.4 version of the firmware?? pretty please I have spend a hole day lookin and can not find it!! Thank you in advance.
btw why I should to turn on my radio (tx) first (then plug the lipo to my kwad) to connect my kwad? how to set like on crossfire (when I plug my kwad first then turn on my radio they can connect automatically)?
If you raise the wifi hotspot timeout, you can extend the time before wifi kicks in to like 10 minutes or some other very long value. But using wifi to configure the system will become difficult since the RX will need to be told to go into wifi mode manually. If you don't have your controller, you'll be waiting a long time.
Hey Mr Bardwell. I wish you'd released this video a day earlier as it would have helped me out 2 days ago (and saved me a whole load of head-scratching!). I was trying to flash my new Ranger Micro TX and bind it with a Naminmo RX from an old build. Flashed both to the latest ELRS f/w with my passphrase ... but no successful bind?!? My last resort was to set my passphrase for both RX/TX using the runtime options .... and bingo, it worked. Seemed counter-intuitive but, as you demonstrated, it works. Thx for confirming that my approach wasn't pure luck :)
Hello from Spain Joshua. Thanks for the video!!! What sticks of gimballs are those?Could you make a video with the sticks for...(for example) Radiomaster controllers?? I think it would be a good idea. See you!!
I have a foxeer elrs receiver I just installed and it is connecting to my RadioMaster Pocket but in betaflight it shows no reaction to stick inputs. RX and Tx are reveresed can you think of anything else it might be?
Very good-gets you most of the way. Mainly there's lots of other misinformation on the web of which this steers you clear. There were still problems for me identifying device category/device names, as you don't get this information when you buy your drone; even the update page with DYI... category wasn't of much use. I wasted a lot of time because I didn't know my just purchased drone was ELRS v2, not the v3 on my RM Boxer-I just assumed the latest ELRS would be installed on a new drone.
@@gregorydahlwell maybe not. In order to flash an frsky r-xsr, you have to use a tiny adapter (if you have a connecter on your receiver, otherwise you need to solder wires) and then you need to plug that adapter into your radio JR bay and make sure that the wiribg is correct. Then you need to put the firmware on your radio in order to flash your receiver. And I don’t even then mention the whole access/accst v1/v2 eu/us mess for the firmware file. ELRS is so much easier
Push button on reciever to go into bind mode, push button on radio to bind, boom...go fly. I have never updated a frsky reciever. If it flies, why mess with something that works great. I am very reluctantly trying elrs. Only because I can't find the micro recievers I like. I would rather fly more than sit in front of the computer more.
hello sir, thx for making such a good video. allow me for ask sir ^^ is it possible to binding the elrs tx module with the receiver elrs without using radiomaster remote controll? i have elrs tx module ES happymodel 2.4 Ghz, and receiver elrs epdual. thx sir
Does each expresslrs rx have a different binding phrase, or do all my rx's share the same phrase? Maybe dumb question, but since I'm migrating over from Spektrum where the binding procedures are different.
Hi Joshua. Is it ok to flash my elrs receiver without attaching it to my fc? I'll just power it up with an external dx power supply and do these steps. Would this be ok?
Thanks to Joshua I now have my first 5" quad that I succesfully flew at a farmers field, over the moon...could never have done it without you, 11 hours pre traiing on the lift off simulator game a me a good start to learn this difficlt craft that makes it so much more rewarding when you see something you have built fly so beautifully.
Correct me if I’m wrong, but don’t you select build, and flash when you are updating your TX/RX through the USB /UART choice instead of Wi-Fi? Thanks for the video.
5:47 Does it matter which .bin file you use to update the rx? I noticed you used the firmware.bin file, whereas I've only ever used the one with the name of the rx. All my rx's work great so I guess I've answered my own question... but why the 2 .bin files?
Someone can help me how to fix stuck in loading??. I update my external module version to v3.2.0 and when i open the expresslrs to my Taranis QX7 tx to enable wifi the tx. It's stuck in loading. 1 change and test all Bauds to 400k to 5.25mb
Does anybody know why only FLASH is available in ELRS config and not BUILD. The build option disappears as soon as I select the RX unit I'm using leaving only FLASH available,,,,which doesn't work. Many thanks. 😍
I Had this Problem now two Times. Bought definetly a betafpv Diversity. While flashing IT told me of course Missmatch and that i need to use Happymodel target wich i did. The flashing was kinda Not really working as usual but the RX was bound ( i got the telemetry Info at least) so IT Had Connection but my Quad didn't respond to anything.
If you have a F4 and it seems like you did everything right but it’s not working you might need to use a different UART. I had to swap the RX and my Vista and it started working as expected.
I'm super stuck and I cannot find anything to help with the issue. When I open ELRS configurator and set everything up, after I hit "build" I DON'T get the .bin file for my HappyModel 2.4... the file explorer opens, and the folder name in which the .bin file should be correlates to the ELRS module, but no .bin file... Does anyone have any ideas?
U saved me! Lol I finally figured out why I wasn't seeing elrs in betaflight lol now I need to figure out the rest of this mumbo jumbo lol thanks joshue!
I bought a HAPPYMODEL EP1 DUAL 2.4G RX and it came pre-flashed with UNIFIED_ESP32_2400_RX Firmware. When I try to flash the firmware via passthrough I get this error: "Wrong target selected your RX is 'HAPPYMODEL_EP_DUAL_2400_RX', trying to flash 'UNIFIED_ESP32_2400_RX'". How can I fix this?
Updated my Radiomaster Ranger TX firmware no problem but the RP1 RX is a problem. After downloading and extracting the firmware I try to upload it and get an error: Targets Mismatch which explains that the factory firmware is not matching what I want to upload - press FLASH ANYWAY to overwrite it. Which I do and then get an ERROR[4]: Not Enough Space. Anyone know how I get around this as the TX will now not bind to the RX?
Joshua, I’ve watched both. I still get some flashes that just fail and brick my RX! If I evened out the money btw wasted rx and crossfire rx it’s prob same price. It prob user error but I’m doing nothing different than you… Update: I watched it in depth (this current video) and realized I may have been trying to flash the other file, not the firmware.bin - does this make sense that I would still at times get successful flashes using that other file labeled “3.2.1” for example?
I prefer to connect with my phone, define my home network, and I then I don't have to bother with connecting to it anymore as it'll just be on my network. ELRS Configurator works exceptionally well that way.
My problem with that is the RX wifi is very short range so it can't always reliably connect to my wifi. It it can always connect to my phone which is right nearby.
@@JoshuaBardwell Ah, this is true. My access point is only about 4-5 feet away from where I do my configuration, so it connects without issue. The PCB antenna on most of these boards just doesn't cut it for anything beyond the room its in.
Thank you so much, mate!! This video helped me after few hours of research I wander how i possible know that to update firmware for happymodel esc900rx. First I have to unzip file and then after i've seen "U dont have enought space" error. I should try again with that one unzipped file )))
Can anyone help me setup my kiss v1 fc with happymodel ep1 rx. I am so lost and am starting to regret purchasing this happymodel after more than 2 days of trying to get it set up... :(
I woudl suggest spending $15 or so on a USB wifi adapter for your computer. There are ways to work around this, but they're a pain in the butt, and it will be money well spent.
My device name is DIY_2400_RX_ESP8285_SX1280. It doesn't show up in the expressRLS configurator. DIY Mini ESP32 SX1280 2.4GHz TX is the closest thing but is incorrect. Can someone help me?

What about another super simple way? As I know if You on the same version on TX and RX You can plug receiver 3 times with battery and press BIND in LUA script
Hello Joshua, first I have to say I LOOOOOVE your videos. I consider it a "Good day" when I learn something. Thanks to your videos I've had lots of them. On to my question... I have a Baby Ape Pro V2. I'm try to set the Bind phrase on the ELRS module. Connecting to the on board Wifi it tells me... From here you can update your Receiver module with BETAFPV_2400_RX firmware Rev. 2.5.2 (6d9d57) ISM2G4 My question is, what should I do? Upon checking in ELRS configurator, there is no exact match for that name. But the Flight Controller and the ESC are both AIO components. Maybe the ELRS receiver is also AIO? Should I try the firmware labeled BETAFPV_AIO_2400_RX?? If it doesn't work, will it be bricked for good?
Im so glad my radio and rx came with 3.whatever, this would of took me forever. Tried to set a bind phrase and kept getting a failed message so i just did the bind process and got lucky lol
I think one thing that always gets overlooked is that ELRS has terrible WIFI range. I'm sure this is for security reasons, but you really need to make sure you are as close to your router as possible when flashing your hardware.
@JoshuaBardwell it's a pavo20 elrs version but I couldn't get into betaflight one day so I flashed it but now I can't find elrs on the receiver tab, pretty much everything else there tho
But Josh..... by the time you have connected your bluetooth to the receiver, I have already plugged and unplugged it twice, plugged it in a third time and hit 'bind' on my transmitter. Done done and done.
It’s wifi not bluetooth, and this video isn’t just about binding but also flashing. Although what you are mentioned works, using a binding phrase means it just works out of the box. And you will eventually update you firmware. So you just have to do it once and forget about it.
That's fine, but it doesn't work unless you know they're on the same firmware, and these days the RX usually comes with 2.x and the module has 3.x, so you're going to have to flash it anyway.
i was called out for not watching the definitive guide and now... i'm going to watch the definitive guide...
At the time of posting, this video is 100% correct for v3.2.x….
BUT, in v3.3 which is currently in release candidate, the bind phrase workflow has been “fixed” so that wherever you last set it from (configurator, webui etc.) will take priority. This means you don’t need that last step to set the bind via webUI anymore.
Damn you devs, always fixing things right after I document the bug. FWIW I still would set bind by webui over flashing, if I had the correct version.

Your humbleness is crazy, And I plan on joining your Patreon soon also I have watch all three elrs videos this time it's just with my actual radio and my first radio.
I feel like you made this video out of spite.
😂😂. I got that feeling in the first few min. I'm going to go watch the 45min version 😂. We love you bardwell
I’m a bit confused. There was two bin files to choose from to update the rx. Why not choose the lower one ??
They are identical, just one is named more descriptive. You can pick either one. It doesn't matter.
@@JoshuaBardwell Awesome. Thanks so much. You’re a big help and the reason I can maintain my sanity in this sometimes confusing hobby.
I’m joining your patreon now.
7:38 even tho you didn't show your binding phrase you shoved your uid (unique identificatior) what if someone types that into rx tx they can basicaly controll your stuff, i think you can blur it somevere in yt studio, great video about elrs JB have a great day
I have crossfire and don't need elrs. when radiomaster stops messing around and releases a boxer max I will buy that and probably watch one or maybe even 2 of your many many ELRS videos. jeeze. :)
I got 3 elrs nano and mico modules and 9 rx's . One worked until jb weld doesnt stick the tee antenna to carbon fiber and it shredded in the props . Could not fix the ufl connector . All nine said factory firmware matched but doesnt . Buy a computer and cable anyone ? I learned my lesson . Chasing a more and more expensive carrot no sir every week upgrade videos
so If I do not want to flash the firmware, but just want the advantages of having a binding phrase, can I just enter the binding phrase in the 10.0.0.1 web page and save it to the drone and radio that way? [your video at 7:40].
I can not figure out how to install my rp3 reciever in my drone. Ive soldered everything correctly and I made sure there were no shorts. I turn it on and the reciever just flashes for a split second and then nothing happens. Do I have to give it power before I solder the TX and RX wires or what am I doing wrong?
Awesome video. You are awesome!
However, as a software developer for 30 years, I find this to be the worst design for software firmware updates I’ve ever seen. And you have some how found a way to make this work for us. Thank you!!
I have never had this much trouble BINDING a transmitter! I have been trying to Bind my RadioMaster Ranger ELRS with my new Chimera7 Drone for the last 2 1/2 hours with no luck (So FRUSTRATING)... Until this 10 minute video!!! Thank you, thank you, thank you! (I wish there was a way to send you $20 on here!)
Watched this video till the spi internal aio whoop not the same instructions part. 5:30 😢 I'm having trouble binding multiple betafpv spi whoop boards with my elrs tx. Some will bind after hitting the bind button in betaflight others go into bind mode but don't ever bind. I only have about 4 and got 2 to bind so far and I didn't use a bind phrase I just pushed bind on both rx and tx and boom they were connected. But is it really connected? I kept getting what seemed to be like failsafes during simple flights around my house with one board. 🙃 honestly I thought I was switch from tbs crsf to this to not only save money but to have something that works consistently and efficiently but I've spent all night trying to use the configurator to bind/flash the rx / tx and kept coming up with failures. I've given up for now😅 i did buy some normal elrs rx's so ill come back to this once ive mastered the spi based internal rx's first...
I been watching your videos for a while bit you hit the nail on the head in this one when you said I just want to bind and fly.lmao
I did watch the long video to first tho and I'm still lost so I will have to watch it again and probably again.
Thanks Mr.Bardwell your the coolest!
TwistedFPV
im glad im not the only one actually following both n still 100% stuck - i love the guy too but this is the 3rd Bardwell video that 0% works - did u ever get this to work if so how??
Yeah I got it figuered out for the most part how about you?Do you need some help?@@Simply6FPV
Thank you Joshua you have saved me from spending days on getting my gear running, but I have an issue with a Zorro ELRS TX, it is bound to the RX as it says on the radio when I remove the battery from the RX and when I reconnect the battery it says connected again, on BF I can see that the Roll, Pitch, Yaw and Throttle work but not the switches. I have tried everything but nothing else works. dont know what else todo.. or what direction you can point me. Thank you !!!
My procedure is to connect to the receiver with WiFi and set it to connect to my home network. Then I build and flash from the configurator. This has worked for every receiver brand except the Axis Flying receivers I have. With those, WiFi did not work correctly until I had upgraded once. After that I am able to use the same method with home network set for future updates.
How did I miss this! Been struggling for days, thank you.
you can also use your phone to check the firmware version instead of having 2 wifi adapters and switching back and forth between networks on your desktop
Oh I watched the 1st video, still lost! Back for more torture!
I had a surprisingly smooth experience with elrs spi binding on a mobula6. It wasn't binding probably because the elrs came from factory with erls firmware 2.x
I flashed betaflight 4.4.2, went to the receiver tab, selected SPI and entered my passphrase.... thats it, no wifi needed, no compiling, no need to do anything on the Transmitter.
Same here. Very satisfactory experience
ELRS via SPI is the easiest setup since it's baked into the FC FW. It's almost D8 simple. The UART FC's like the NewBeeDrone are a BAD idea.
Respectttttt!! More great coverage on an otherwise challenging part of ELRS 😅
I am so new to ELRS, I'm still itching from my shrink wrap!....I still haven't attempted to set up my first ELRS micro racing drone, being an airplane guy, thus wanting the security of ELRS. Anyway, you do not mention with new receivers of "any" type, placing the LUA script of it into the Tx card tools file. Betafpv, where I got their micro PWM receiver, states to do this. So, do you?
Hey, I have Cinerace20 and I cannot connect with Wifi. Its flashing fast but I do not see it on any device. Radiomaster works good bit Cinarace is not visible and cannot connect:( do you know what is it?
My man! thanks for this video you got me going with my 1st drone, GOD Bless you man!
always great value watching your channel
I've flashed ELRS receivers various ways, WiFi, Betaflight passthru and a USB/TTL bridge.
Whilst the WiFi approach specified here is undoubtedly very convenient, one thing I've found one needs to watch out for is WiFi range - the tx power from the receiver seems very low. Move the PC antenna and Rx too far apart and it'll lose connection pretty quickly - mine does anyway.
It hasn't happened to me yet, but I wonder what might be the result if it lost connection in the middle of flashing. Don't know but suspect one might have to force the Rx into boot mode and reflash with a USB/TTL bridge.
Important to make sure the WiFi connection is solid, anyway.
When I try to import the new firmware to the receiver, before it can say update complete, the receiver switches back into its initial binding sequence and disconnects from my computers wifi. Im not sure if the issue is my soldering or what, because everything else seems to be working so far... any would be much appreciated.
Hey Joshua I don’t know if you will get this question or not I just got my radiomaster pocket and my baby ape 2 pro and every time I try to flash I keep getting a build error code in express Lrs configurator do you have any idea why ? I’m about to give up any help would be great thank you so much.
This is great was following your perfect build just waiting on motors but I couldn't set my mind to a receiver because I don't have a computer at the moment can you use the app it has a elrs section will that work
I just bought the geprecdark star 20 and y cannot flash it. When i tried to do it trough wifi mode, it appears that the receiver is beta fpv 2.4 nano. I dont know what firmware set up, if it is elsr beta 2.4 nano or geprec 2.4 nano as the manual said. What do you suggest?
Will a rx light up if plugged by usb only? I don't have the power lead soldered yet onto the fc aio. But I wanted to c if I can update or check the elrs rx via usb power only.
is it okay to update a bind and fly receiver ? I don’t want to risk messing up the settings. at same
time I am not too familiar with fpv and trying to get flying soon!
Is there going to be a review on the darwin fpv quad?
I put all mine to connect to house wifi to use my computer (my wifi burntout on it) but now I can't update outside house. Thinking switching back to 10.0.01
Hi Joshua again!!
Please tell me the distance for the ER4?
I like this for the small floater planes
The radio will select the output for the TX but how far can the ER4 go?
Please tell me
can you help i have a drone with two recivers at the same time and i only wanna use elrs
Hi Joshua, I have a question no one answers.........
Can you change your "pass phrase"?
My friend put ELRS on my TX16s, upgraded it to EDGE but I want to change the pass phrase for the ELRS modgule
Can you tell us how, I would really appreachate it
My ISP will not allow me to directly access device hotspots using this methodology. Any way to do this without using wireless?
hi i have a zorro 4 in 1 radio i notice that the relrs adio master has an express module do you have a video that shows how to change the 4 in 1 module to an elrs??
I was wondering if you would be so kind to give me the link where you mention the partition file to be installed in the TX module when one have a tx that is still in 2.4 version of the firmware?? pretty please I have spend a hole day lookin and can not find it!!
Thank you in advance.
ruclips.net/video/2kcRi1cHejM/видео.htmlsi=PG2zLP4XxgRrFf0r
Thank u Josh for giving the people what they want
btw why I should to turn on my radio (tx) first (then plug the lipo to my kwad) to connect my kwad? how to set like on crossfire (when I plug my kwad first then turn on my radio they can connect automatically)?
If you raise the wifi hotspot timeout, you can extend the time before wifi kicks in to like 10 minutes or some other very long value. But using wifi to configure the system will become difficult since the RX will need to be told to go into wifi mode manually. If you don't have your controller, you'll be waiting a long time.
Hey Mr Bardwell. I wish you'd released this video a day earlier as it would have helped me out 2 days ago (and saved me a whole load of head-scratching!). I was trying to flash my new Ranger Micro TX and bind it with a Naminmo RX from an old build. Flashed both to the latest ELRS f/w with my passphrase ... but no successful bind?!? My last resort was to set my passphrase for both RX/TX using the runtime options .... and bingo, it worked. Seemed counter-intuitive but, as you demonstrated, it works. Thx for confirming that my approach wasn't pure luck :)
Hello from Spain Joshua. Thanks for the video!!! What sticks of gimballs are those?Could you make a video with the sticks for...(for example) Radiomaster controllers?? I think it would be a good idea. See you!!
I have a foxeer elrs receiver I just installed and it is connecting to my RadioMaster Pocket but in betaflight it shows no reaction to stick inputs. RX and Tx are reveresed can you think of anything else it might be?
Very good-gets you most of the way. Mainly there's lots of other misinformation on the web of which this steers you clear. There were still problems for me identifying device category/device names, as you don't get this information when you buy your drone; even the update page with DYI... category wasn't of much use. I wasted a lot of time because I didn't know my just purchased drone was ELRS v2, not the v3 on my RM Boxer-I just assumed the latest ELRS would be installed on a new drone.
Wow, this isn't confusing at all. ELRS really has made the hobby easier to get into than FrSky
😧
You are joking everyone . He is joking .
@@gregorydahlwell maybe not. In order to flash an frsky r-xsr, you have to use a tiny adapter (if you have a connecter on your receiver, otherwise you need to solder wires) and then you need to plug that adapter into your radio JR bay and make sure that the wiribg is correct. Then you need to put the firmware on your radio in order to flash your receiver. And I don’t even then mention the whole access/accst v1/v2 eu/us mess for the firmware file. ELRS is so much easier
For me frsky is easier. Bar none . 👍
Push button on reciever to go into bind mode, push button on radio to bind, boom...go fly. I have never updated a frsky reciever. If it flies, why mess with something that works great. I am very reluctantly trying elrs. Only because I can't find the micro recievers I like. I would rather fly more than sit in front of the computer more.
hello sir, thx for making such a good video. allow me for ask sir ^^
is it possible to binding the elrs tx module with the receiver elrs without using radiomaster remote controll?
i have elrs tx module ES happymodel 2.4 Ghz, and receiver elrs epdual.
thx sir
Does each expresslrs rx have a different binding phrase, or do all my rx's share the same phrase? Maybe dumb question, but since I'm migrating over from Spektrum where the binding procedures are different.
You can decide how you want to do that, but typically all your RX would have the same binding phrase.
The configurator looks different and every time I try to flash my radio (the radiomaster Zorro) it fails
Cant find DiscardVirtualMemory .DLL file in the directory and the expresslrs configurator dont launch... Anybody know a solution?
Me simple. Me no understand long video. Me happy from this video.
Thanks a bunch, Joshua! ExpressLRS rocks!!! 😊
Stay safe there with your family! 🖖😊
Hi Joshua. Is it ok to flash my elrs receiver without attaching it to my fc? I'll just power it up with an external dx power supply and do these steps. Would this be ok?
Yes that's fine.
Thanks to Joshua I now have my first 5" quad that I succesfully flew at a farmers field, over the moon...could never have done it without you, 11 hours pre traiing on the lift off simulator game a me a good start to learn this difficlt craft that makes it so much more rewarding when you see something you have built fly so beautifully.
Correct me if I’m wrong, but don’t you select build, and flash when you are updating your TX/RX through the USB /UART choice instead of Wi-Fi? Thanks for the video.
Correct. But I"m not flashing through USB/UART, I'm flashing through WiFi.
5:47 Does it matter which .bin file you use to update the rx? I noticed you used the firmware.bin file, whereas I've only ever used the one with the name of the rx. All my rx's work great so I guess I've answered my own question... but why the 2 .bin files?
They're identical. It doesn't matter. I don't know why there are 2 of them.
Thanks!
Someone can help me how to fix stuck in loading??. I update my external module version to v3.2.0 and when i open the expresslrs to my Taranis QX7 tx to enable wifi the tx. It's stuck in loading. 1 change and test all Bauds to 400k to 5.25mb
Can i use a happymodel ep1 RX with Radiomaster TX ?
Does anybody know why only FLASH is available in ELRS config and not BUILD. The build option disappears as soon as I select the RX unit I'm using leaving only FLASH available,,,,which doesn't work. Many thanks. 😍
Pick the wifi option. It's dumb.
can you help why ican bind my rp4 receiver
Your content is amazing!
Is there any way you could bind an elrs receiver without getting on your computer and doing all this complex stuff?
Yes. ruclips.net/video/H5OnozIqJCA/видео.html
Also in ELRS 3.4, the button can be used to trigger binding.
So there are many ways.
So after both the TX and RX have the same binding phrase, they will get automatically bound when powered up?
Correct.
No, the definitive guide was great!
I Had this Problem now two Times. Bought definetly a betafpv Diversity. While flashing IT told me of course Missmatch and that i need to use Happymodel target wich i did. The flashing was kinda Not really working as usual but the RX was bound ( i got the telemetry Info at least) so IT Had Connection but my Quad didn't respond to anything.
Can we do like this with AIO FC ? I'd consider use Happymodel X12 or F4 1S 5A FC. I usee tiny
Yes, as long as the ELRS RX is UART-based not SPI-based.
looks like my drone is not switching into WIFI mode after powering up... any suggestions?
Manually force wifi mode by holding down the bind button for 5 seconds.
If you have a F4 and it seems like you did everything right but it’s not working you might need to use a different UART. I had to swap the RX and my Vista and it started working as expected.
I'm super stuck and I cannot find anything to help with the issue. When I open ELRS configurator and set everything up, after I hit "build" I DON'T get the .bin file for my HappyModel 2.4... the file explorer opens, and the folder name in which the .bin file should be correlates to the ELRS module, but no .bin file... Does anyone have any ideas?
same problem, did u find a solution ? thanks
BetaFPV 2.4Ghz nano rx won't start wifi mode. Any1 experienced this? Any solutions? Thanks
U saved me! Lol I finally figured out why I wasn't seeing elrs in betaflight lol now I need to figure out the rest of this mumbo jumbo lol thanks joshue!
Does this work with a Mobula 6? I'm at the first step, and it doesn't seem to be emitting the wifi signal? Thanks.
If Mob6 has SPI receiver, then it doesn't do WiFi. ruclips.net/video/G1dK7nk5Ds4/видео.html
@@JoshuaBardwell thanks Joshua. ⭐️⭐️⭐️. Really appreciate all your hard work!
I bought a HAPPYMODEL EP1 DUAL 2.4G RX and it came pre-flashed with UNIFIED_ESP32_2400_RX Firmware. When I try to flash the firmware via passthrough I get this error: "Wrong target selected your RX is 'HAPPYMODEL_EP_DUAL_2400_RX', trying to flash 'UNIFIED_ESP32_2400_RX'". How can I fix this?
Enable the "force flash" option.
YOU know i am gonna learn how . i cant be stopped . thank you .
Updated my Radiomaster Ranger TX firmware no problem but the RP1 RX is a problem. After downloading and extracting the firmware I try to upload it and get an error: Targets Mismatch which explains that the factory firmware is not matching what I want to upload - press FLASH ANYWAY to overwrite it. Which I do and then get an ERROR[4]: Not Enough Space. Anyone know how I get around this as the TX will now not bind to the RX?
ruclips.net/video/2kcRi1cHejM/видео.htmlsi=UTfWw_Jw8tIl1Nv0
Joshua, I’ve watched both. I still get some flashes that just fail and brick my RX! If I evened out the money btw wasted rx and crossfire rx it’s prob same price. It prob user error but I’m doing nothing different than you… Update: I watched it in depth (this current video) and realized I may have been trying to flash the other file, not the firmware.bin - does this make sense that I would still at times get successful flashes using that other file labeled “3.2.1” for example?
Either .bin file works, even of you rename them :)
I’m confused more than ever. I’ve been trying for three weeks to bind my new Boxer to a RP1 RX and it does not work
I prefer to connect with my phone, define my home network, and I then I don't have to bother with connecting to it anymore as it'll just be on my network. ELRS Configurator works exceptionally well that way.
My problem with that is the RX wifi is very short range so it can't always reliably connect to my wifi. It it can always connect to my phone which is right nearby.
@@JoshuaBardwell Ah, this is true. My access point is only about 4-5 feet away from where I do my configuration, so it connects without issue. The PCB antenna on most of these boards just doesn't cut it for anything beyond the room its in.
I was about to say the same thing. Then the build and flash button works without any issues
Thank you so much, mate!!
This video helped me after few hours of research
I wander how i possible know that to update firmware for happymodel esc900rx. First I have to unzip file and then after i've seen "U dont have enought space" error. I should try again with that one unzipped file )))
Can anyone help me setup my kiss v1 fc with happymodel ep1 rx. I am so lost and am starting to regret purchasing this happymodel after more than 2 days of trying to get it set up... :(
I dont have wifi on my computer how do i bind it and update it?
I woudl suggest spending $15 or so on a USB wifi adapter for your computer. There are ways to work around this, but they're a pain in the butt, and it will be money well spent.
My device name is DIY_2400_RX_ESP8285_SX1280. It doesn't show up in the expressRLS configurator. DIY Mini ESP32 SX1280 2.4GHz TX is the closest thing but is incorrect. Can someone help me?
What model receiver is it?
@@JoshuaBardwell Built-in Receiver: Serial ExpressLRS 2.4G / Frsky SPI from the Brushless betaFPV f41s5a flight controller. It's built in ExpressLRS and also a built in ExpressLRS transmitter, the literadio 2 se. I can connect FC to betaflight and transmitter to its respective software, but I can't get the transmitter inputs to show up in betaflight. Help pls
Is the password supposed to be different for every other RX that I connect to my TX16, or the same?
All the same.
What about another super simple way? As I know if You on the same version on TX and RX You can plug receiver 3 times with battery and press BIND in LUA script
the binding phrase bytes is on display
Hello Joshua, first I have to say I LOOOOOVE your videos. I consider it a "Good day" when I learn something. Thanks to your videos I've had lots of them.
On to my question...
I have a Baby Ape Pro V2. I'm try to set the Bind phrase on the ELRS module. Connecting to the on board Wifi it tells me...
From here you can update your Receiver module with BETAFPV_2400_RX firmware Rev. 2.5.2 (6d9d57) ISM2G4
My question is, what should I do? Upon checking in ELRS configurator, there is no exact match for that name. But the Flight Controller and the ESC are both AIO components. Maybe the ELRS receiver is also AIO? Should I try the firmware labeled BETAFPV_AIO_2400_RX?? If it doesn't work, will it be bricked for good?
Im so glad my radio and rx came with 3.whatever, this would of took me forever. Tried to set a bind phrase and kept getting a failed message so i just did the bind process and got lucky lol
If the rx doesn’t start to blink fast and go into WiFi mode is there a way to force it ?
Most of the time this means your FC has an SPI-based receiver that doesn't do wifi. For mroe: ruclips.net/video/G1dK7nk5Ds4/видео.html
@@JoshuaBardwell Got it thanks
I love your videos❤ everything explained easy for primates live me😂 I would like you to put a video on how to install gyro flow in android! Thanks❤
I think one thing that always gets overlooked is that ELRS has terrible WIFI range. I'm sure this is for security reasons, but you really need to make sure you are as close to your router as possible when flashing your hardware.
So if u have aio controller with elrs this won't work?
These instructions don't work with SPI elrs rx. But many aio have serial rx.
@JoshuaBardwell it's a pavo20 elrs version but I couldn't get into betaflight one day so I flashed it but now I can't find elrs on the receiver tab, pretty much everything else there tho
@JoshuaBardwell tried to do a cli dump from betafpv but don't think it worked 🤔 lol I definitely could use some help later today or tomorrow!
I finally figured it out lol all i had to do was watvh until roughly half way and bam, it hit me what i needed to do in betaflight lol@JoshuaBardwell
@@JoshuaBardwellnow I have to get the elrs module for my taranis qx7 I got for a steal today! He gave it to me! Definitely helps me big time!
What is a “binding phrase”?
But Josh..... by the time you have connected your bluetooth to the receiver, I have already plugged and unplugged it twice, plugged it in a third time and hit 'bind' on my transmitter. Done done and done.
It’s wifi not bluetooth, and this video isn’t just about binding but also flashing. Although what you are mentioned works, using a binding phrase means it just works out of the box. And you will eventually update you firmware. So you just have to do it once and forget about it.
That's fine, but it doesn't work unless you know they're on the same firmware, and these days the RX usually comes with 2.x and the module has 3.x, so you're going to have to flash it anyway.
What do I do after I have done this
Pick up here and keep moving forward with your setup. ruclips.net/video/EDnQEep2X4I/видео.html
