I'm trying to change the settings on my esc's. This is done similarly to how esc calibration is done, You start with pwm value high when the esc's are powered on and you set the pwm value high or low at specific times to select settings. I couldn't figure out a way to get PX4 to act as a passthrough for my RC transmitter and just send the throttle channel to all esc's so I was hoping to do this through the "pwm" app in nutshell. However I can't get the pwm app to actually do anything. I've tried "pwm arm", "pwm test -a -p 1100", disabling a bunch of the safety circuit breakers, etc. but no matter what I do the pwm values stay disarmed at a pwm value of 900. Does anyone know why the pwm app is not working? Alternatively is there a way to get PX4 to act as a passthrough for the RC transmitter so that I can set the esc's manually with the transmitter?
