Hello,
I see that the when sounds are played during the startup, it is coming from motorsBeep definition from https://github.com/bitcraze/crazyflie-f ... ors.c#L270. I also see that it is changing the speed as well (found from the documentation available in motors.h).

I would like to be able to play sound only *without* changing the speed (i plan to use this during the flight, and speed command will come from the controller. Additionally, I dont intend to use buzzer deck for this). Please let me know how I should change the code to achieve this.

Thanks.

It might be possible to do this but it will definitely degrade the motor response, might still be able to fly though.

You would have to change the motor driver to constantly change the motor PWM in accordance to the sound you want to play. It's not trivial how to do this.
