I have a strange problem on my APM2 quadcopter. It is running lated code 2.4.1 It was working fine the first day, took it out in and flew with no problems. But today, I cannot get it to spin the motors.
I hear the normal ESC beeps, when I arm the motors with the throttle stick all the way down and right I see the LEDs blinking as it did before. The Red LED would then stay solid incdicating motors are armed. But there is no response by the motors when I increase the throttle.
So I connected the board to MP and can see MP indicates correct motor arming on screen. It can also see all the stick signals when I do calibration. I have also tried re-uploading the firmware 2.4.1 again. Nothing seems out of ordinary, except the motors won't spin. What could be the cause?
Similar issue this evening, I did the transmitter calibration again and everything started working again.
thanks. I have also done the transmitter calibration, but it didn't fix for me.
what does the motors test do?
I don't know how to do the motor test. I couldn't find the command in the CLI in the 'test' menu.
'setup' then 'motors'. If you're at 2.4.1 it should spin them in order. Be very careful...
thanks.i have done that and there is no motor spin. but after that I reset the board to factory defaults, then re-installed the firmware. Now it is working, i am not sure if that's what fixed it.
