Motor/ESC beeping issue
Hi guys! A newbie question here, I would be really grateful for any bit of help.

Building my first quadcopter and encountered the motor beeping issue. I have tested all my motor/ESC combinations one by one by connecting the ESC's to the battery and plugging the ESC servo cable into the receiver throttle channel and things worked absolutely fine. Then I've connected the whole setup, motors, ESC's, receiver, Arduino. And that's when the problem occurs - I plug in the battery, the motors make the initial start up sounds, then go straight into the beeping mode. Beeping in sequence one after another, every second or so. And consequently they don't react to the throttle stick movement on my transmitter.

I have tried the recommended solution of teaching the ESC's about the throttle limits but it didn't help. And also separately the motors respond just fine.

My ESCs are XXD HW30A, 920kv motor, Flysky ia6 receiver/transmitter, 11.1V 3s LiPo battery.
Receiver plugged into arduino pins d8-11.

Thank you for any tips or suggestions!

Hi it sound like you need to arm it to get throttle i don't know your board but it will have an arm mode on the phantom it's both sticks down and right

What do you have loaded on the Arduino? That is very relevant, receiver type needs to match what is expected by the flight controller (I assume that is what you are using the Arduino for?).

Is this your first build?
