the Message is, [Gimbal Cannot Receive MC Data]

I search about the error, and some thread said, do IMU/Compass calibration.

But, when i did the Calribration IMU/Compass, Just apeared [Disconnected] and nothing happen.

please Help Me. ... Thank you.

You notice the error after a firmware update or not?
If it's upgraded successfully, then restarting and calibrating makes no sense, it needs to be sent in for repair.
