I am using a Raspberry Pi to connect to the flight controller, and the firmware for the flight controller is rover 4.4.0. I am unable to control the unmanned ship with the controller, and the controller configuration on Blueos is correct. I am unable to unlock the motor. But everything is normal with QGC.

Hi @Mufafafa -  
Welcome to the forums!  
I’d recommend updating to the latest 4.5.5 version of Ardurover.  
Are you getting any errors in QGC when you try to arm the system, and move a joystick to move the motor in Manual mode? You may have failsafe arming checks, like GPS or IMU, that are failing - you can override this via the Failsafe parameters if you’d just like to test your motors…

I tried Rover-4.5.5, but still can’t do motor unlocking, etc.

Hi @Mufafafa -  
I’ll repeat - are you getting any warnings when you try to arm? It’s tough to help without more information!
