I bought my buddy a radiomaster zorro elrs controller, same controller as mine. I tried binding his new controller to a few of my existing quads. The transmitter page on bf showed a very brief response to the controller as I hit bind on the remote, but it would not successfully bind.
Can you only bind a quad to one controller? Why was I unable to bind his new RM Zorro to my old mobula6?

What version of ELRS are you running. You might have a mismatch.

That's probably it! I updated edgetx, but not elrs. Thanks for the idea, will try it out this afternoon.

Unfortunately, updating to elrs 3.3 did not allow me to connect. I still get the same brief indication of connection when I confirm the bind request but then nothing. Any other ideas?

Passphrase? May be receiver ID?

Is reciever ID something that would have to be made to match on both controllers? Haven't read up on it before.

What version of Betaflight is on the Mobula? What ELRS version is on the TX?

Do you have both flashed with the same binding phrase and regulatory domain (eg ISM)?

SPI receivers currently do not work with the D, F, or full-res modes in ELRS. Make sure the Zorro packet rate is not set to one of these modes in the lua.

Both radios are flashed to elrs 3.2.1. And my radio works with the drone, so it's not the elrs version. Both are flashed with the same binding phrase. Both are on ism domain

IT WAS THE PACKET RATE.
rate was set to f1000. Setting it to 500hz did it. Thank you all for your help. Now me and my buddy can fly together!

You are both using the same binding phrase? Not sure how that works, but I would guess that is not recommended if you are both flying at the same time? Maybe you should use two different passphrases, and doesn't 3.x have a loan option where you can loan a quad to a buddy without changing the passphrase?

Will look into the loan option, that would be great. Haven't actually booted them up simultaneously, so the passphrase question is on my mind.

It does work to have the same passphrase without interfering with one another. It seems the drone can only bind to one receiver, so when I bind the mob6 to my friends remote it unbinds from mine, then a quick bind in betaflight brings it back to my controller. I'll read up on the loan option, but for a quick flight together I think this will work.
Long term though, yes, we for sure should not have the same passphrase.

Well, maybe they fought over the same telemetry channel.

Yes, definitely do not operate two transmitters with the same binding phrase at the same time. Each transmitter should have it's own binding phrase.

Use "Loan model" in the ELRS lua to switch models between transmitters.
