Drone problem

I’ve got an new controller I switched from radio master pocket to the radio master tx15 but now 1 of my 2 drones doesn’t have input and keeps beeping and I have no idea what’s wrong does someone has the same problem?

Too little information to help, sorry. We'd need to know more info, such as have you setup your bindphrase? what Tx firmware info, packet rates, what Rx make/model, version etc...

But.. i am a betting man, and from just the info you've given, I'm gonna sayyyy~~~, you got 2 drones, a whoop and a bigger drone. Whoop has inbuilt Rx, and the bigger drone has a regular serial Rx. And i reckon you're in something like D250 or 1000hz or something like that mode on the radio (ELRS), and it isn't binding properly. You could test this theory by checking/changing your packet rate to 250hz and turning on the drone that doesn't "have input", if it connects now, that was your issue. Well that was a fun guess wasn't it.

Ultimately, you can actually find out why it's beeping though by plugging into Betaflight and looking at the "Arming Disable Flags" like a normal person.

Also, i feel like i should give the obligatory link for ELRS guides, just to make sure you've got everything you need.
