@BerndS, I will try, but it would be valuable to understand how it works in the code/hardware as well.Hello @avarnas ;
the best way is to measure the PWM Ticks with an Oscilloscope at Pin 4 at the flat cable connector (see pic. above). If you do not have, have a look into the motor datasheet if they say something about the HAL resolution. If you don’t have this, you can try it out with the AT+E command on sunray to find the exact HAL resolution.
