This problem has been plaguing me in the setup of my drone. I cannot get the motor to spin or calibrate my ESC through pixhawk.
The motor makes beeping sounds on startup (4 beeps =4s battery)
I have made sure that my radio is calibrated. It is and it responds to throttle.
The servo outputs are showing signal to throttle when I throttle up.
I have managed to calibrate and spin the motor directly through the reciever.
Yet, as soon as I arm the plane, there is no sounds from the ESC (which I believe their should be) and the motor does not spin.
