My Brushless Motor is beeping

Do you know why and can you help me ?

ESCs use the musical abilities of the motors to communicate with you.

The motor is telling you something, or trying to.

A first step would be to calibrate the ESC.

ESC EMAX BLHELI Flash needed?

Hey, I got BLHeli 25A connected to brushless motor , it looks it got bad since randomly it will stop rotatating the motor ( I got 2 so I swapped and the issue went to the other motor) I bought a new BLHeli to replace the bad one, isnt it plug n play ? it doesnt work, connected the same way as the old one. both controlled via same pin on arduino nano .. so one motor works and the other one doesnt its not code related but maybe someone here had that issue [25a.jpg] [25a.jpg]
