I think , can you calibrate your ESC ? And min think is when plug your battery to your craft then motor beeping as a stating beep right ?? After this happening ? ---

What outputs are you connecting the ESC to on the FC? [https://docs.px4.io/v1.11/en/assembly/quick\_start\_pixhawk4.html](https://docs.px4.io/v1.11/en/assembly/quick_start_pixhawk4.html) If you are using the PM board shown, connect the I/O PMW from the FC to the FMU PWM out on the PM board and the FMU pins pn the PM will be the servo outputs. ---

Same issue, I have done the things which you had mentioned , enough the beeping is out. Hoping for help to resolve this issue. ---

When it beeps like that it means the ESC is not get the pulse signal from the FC. There could be many reasons for this from hardware to setup of the FC. It’s hard to help with the information you have provided. ---

Whaat…so I have to cut these pixhawk wires? I connect all wires as that pixhawk PM board guide told to do. I/O PWM OUT is connected to powerboard FMU-PWM-In. ESC is connected to M1 and motor power cable to B+ and GND. All is updated and sensors are in place. Still motor just BEEPS…It beeps even I take HereLink out of the fucking system. But works fine when there is battery, esc and receiver. And there is new problem…HereLink cant download parameters on pixhawk…Maybe wrong bitrate but I cant find any places where it is possible to change. ---

Hi, I have the same problem as you do, (w/o the HereLink) but I can’t get this ESC stop biping. Have you found a way to fix this ? Thanks Tim ---

Your throttle not below 1100 PWM so , make sure your throttle position is 1000 to 2000 PWM ---

Mee too It looks like every time pixhawk is entering into callibration mode I’ve done radio callibration , and esc callibration. motors are spinning after callibration. Once battery plugged out and connected back, again motors start beeping … Throttle was down after callibration still beeping sound goes on … But when ever I press the safety for 2 seconds, switch from blinking red led turns to solid red and then motors sounds like calibrated and sound stops Again disconnect the battery and reconnect problems starts back again …motor beeps How to exit from callibration mode…ites struck in it… Motors sounds continuously… ---

Similar issue Motors got calibrated , I was able to run them And once I disconnect the lipo and re connect back again motors are beeping The throttle was down while powering back Radio was calibrated before esc callibration! Still every time I power on motors beeps But if I press safety switch for 2seconds till solid red …motors gives callibrated sound And stops sounding. They r quiet. Once dis-connect lipo and reconnect …beeping restarts… What could be the issue?? ---

Please don’t necrobump a post; create your own post with your questions. Things move really fast in our community, and on top of that, the development environments can be vastly different, and as such, what worked for someone a few months ago might not work for you today. ---
