Here is from the telemetry
I can't find anything wrong. I can also put it in open_loop mode and enter "pwm 1300" etc from CLI without problems.
I´m starting to think the beeping is because the engine is constantly trying to stop and start? It does not disarm. So it is perhaps noise on the PWM signal causing the ESC to constantly start and stop when the S/N ratio get to high (when turning throttle off?) I dont have any scope here so I cant check the waveform.
If I use a PWM output from AQ that is inactive nothing happends to the ESC, but as soon as I put the output in the motor mixing table it starts to beep.
I have removed the heatshrink and tried with a different PWM wire away from the power wire, no change. I find it really strange that this only happends to one of the ESCs (some sort of bad shielding on it?)
Would it be an idea to try with different PWM_LO_VALUE and PWM_MIN_START parameters?
