ExpressLRS Binding for beginners and the most common problems I see...

See other vidoes on ELRS: • ExpressLRS, the open-s...
Worth noting that if you set a PASSPHRASE on the ELRS RX and TX then the need to force the receiver into 'bind mode' should be unnecessary. However, it will only work if all of the other pieces shown are correct too..

Lee: Another great video! Thank you for covering the gotchas in detail and for repeating the key issues, especially that there are 2 different ELRS vs Express LRS firmware choices to match versions of the software (2.0). Excellent videography & audio. Keep up your great work!

Thanks Lee. I did setup this receiver but couldn’t get the servos to move for some reason. Didn’t investigate it enough. I’ll try again and let you know. I finally became a patron today :) it’s way overdue. Great work.

[@kaptkrunchfpv]

Hello, I am new to ELRS, I have the Radiomaster TX16s mkII , happy model tx24 pro module and a betafpv elrs lite receiver. I managed to get the module flashed to 3.01 and the receiver flashed via wifi to the same, I did include a binding phrase. When I power cycled after flashing the rx goes into a super fast blink immediately when powering up, I am also unable to bind to it. Any idea? I am at my wits end. I do have another receiver on the way just in case...

[@helihobby]

Thanks for your great video... help me how to enter the binding mode successfully...

[@AndrzejRoszkowski]

I had a problem with Matek 2.4 receivers - after flashing from "configurator" or "web page", receiver was constantly rebooting (connect it with USB2UART, then open "serial console" in configurator, if it shows "faults", dumps lot of garbage and uC registers) - what helped was a flashing tool i've found on Matek's page "ESP_NodeMCU-PyFlasher.exe". I've selected "clear eeprom" or similar option (erase flash, do not remember now) and flashed elrs. It seems that original firmware has different configuration area (size or actual parameters) that are not picked up by new version, and ELRS Configurator is not clearing it by default. I had same problem with both - ELRS-R24-D and ELRS-R24-S.

[@ArmageddonYT]

Thank you for all the advices 👋

[@sarkisfitness1112]

I got a question, do you have to flash the TX 16s radio or the elrs receiver when new? Or can you just get the stock version of each and just bind and fly?

[@Painless360]

Binding will normally only work if both the radio and receiver are on the same major version of ELRS.. Best of luck.

[@fsbollox]

THANKS cheers Painless I am using groud vehicle with beta fpv pwm supper p with MT 12 so I assume its the same thank you bro

[@hspeed3656]

Great video Lee. Looking for steps for changing channel 5 to 6 in expresslrs so it works with Kopilot for mode switch, since Channel 5 is only 2 position and need 3 for kopilot. Also have you tried the Matek CRFS to Sbus for elrs and if so same issue, How to change channel 5 to 6 for mode switch.. HELP please. Thanks in advance for any help or suggestion. Have a great day

[@Painless360]

In the BetaFPV receiver you can assign the PWM outputs to be any channel you want. On the Matek PWM receiver they don't pinout CH5..

[@user-cq8rl3it2k]

Hey great video! just stuck on what you mean that the binding phrase is set the same on BOTH TX and RX? i know i can flash the binding phrase onto the RX but how do i set the binding phrase on the TX controller? i have a TX16S Thanks a lot!!

[@doand1257]

You must have the same binding pphrase on your ELRS TX external module

[@darrylfrey6711]

I have the betaflight rx and tx module on my tx16s MK2 updated both. Installed rx in airplane and it went through binding process flawlessly. Took it to the field and flew the airplane. Following weekend took it back out to the field and nothing. Just a blinking blue light. This mess is so frustrating

Great video on this topic. Unfortunately during flashing to the latest version via Wifi, I bricked that 5Ch receiver. I know there is a device available to unbrick those nano and other receivers. But no manual how to do that with this receiver. Do you have an solution for this? Thanks anyway.

[@Painless360]

I'll add it to the list of things to investigate.? Stay tuned!

[@vipertruck100]

@@Painless360 Thank you Sir. For me in Canada it is probably cheaper to just buy another receiver than buying that unbrick dongle from BetaFPV if it even would work. But still it would be nice to recover the bricked one. Cheers.

[@ChainsawFPV]

My HappyModel module has 2.0 and the BetaFPV RX I got are on 1.0 Do I flash the RX to 2.0 or downgrade the TX to 1.0??? Or will they bind without being on the same?

[@Painless360]

Update the reciever to version 2.x and it should all work... Best of luck

[@Painless360]

Only if that model provides support for an additional ExpressLRS reciever. I don't expect that it will easily. DJI only want owners to buy and use their stuff... Best of luck

[@MrVasmikey]

Make sure your default gateway router is not set for 10.0.0.1 as mine was because the RX web page won’t come up. I had to re-ip my router to 172.16.0.1 for it to work.

[@nadrojgansi1345]

Hi, this has been soooo helpful because i mistakenly bought the Radiomaster tx12 Mk2 elrs version for my 3D and sports planes.. SO now I'm so relieved i can still use it. Question though: can I use the 5th channel as the slave of the 1st (aileron) for a 2-servo aileron setup without adverse effects?

[@Painless360]

At the moment the 5th channel needs to be 'high' to enable all of the features you want 'on' when flying. You can remap the other channels on the Rx so that CH5 isn't wasting an output.. See kzbin.info/www/bejne/aV7PaKB7oNF4j5Y

I was hoping you can help me, I was able to bind my rx but I cannot get ch2 to work..: I’ve verified the servos all work, adjusted and made new models in my zorro and ch2 whether it’s ele or rud it won’t send a signal while the other 3 work great

[@Painless360]

Check that you can see that channel moving on the radio ok, then move one of the known good servos to that output. If still no joy, check that the PWM output with the issue has power... Best of luck!

[@michael88997]

Good info mate. Don't forget the bind process. Most newer elrs receivers can enter the bind phrase be powering on and off the FC 3 times in quick succession. This will force the FC to enter bind mode. Don't bother typing bind_rx into the CLI of betaflight....this simply wont work. Also make sure that the ELRX RX firmware is the sameas the ELRS TX firmware. If not then they will also not bind.

It would be worth mentioning that binding is a really uncommon thing to be doing in ELRS. Setting a binding phrase while flashing makes this whole process unnecessary.
