Hey,guys.when i try to calibrate my esc the mp says set param error,Please ensure your version is AC3.3+. I’m sure this is a pixhawk.I search similar topic but seems other guys didn’t solve this problem.Anyone knows how to solve this?
If the board is a pixhawk, then you should update the Firmware to ArduCopter 3.6.10.
That should solve your problem.
thank you i‘ll try that
