Hello. I've purchased my Mavic Pro a week ago and didn't have a single successful flight with it.
[size=14.6667px]I keep getting "Compass Error. Exit P-GPS mode..." error. Both compasses are working and are calibrated in an open field. (tested by putting metal thing to compasses - both react as they should). I believe IMU calibration is good too. I did sensor calibration on DJI assistant 2 as well as the remote controller calibration on the app.

[size=14.6667px]I've tried flying it in different locations and sometimes I can get off the ground pretty ok, but today I understood one thing - when I yaw the drone 360deg (doesn't matter direction) the controller instantly gives me an error "Compass error. Exit P-GPS mode"... and the drone starts to drift. ( I still can control it, and after ~10 seconds of Atti mode error disappears )

[size=14.6667px]I've monitored compass interference levels before flight and during the flight - both are green and working well with a value not higher than 40.

[size=14.6667px]I've tried doing compass calibrations in different locations but I still get "Compass error" as soon as the drone yaws. I've never get "calibration failed" error though. Sometimes when I'm doing Compass calibration I just do the "dance" but it doesn't get to the next step of calibration. Like ever. So I cancel calibration and start again. I'm sure that I do the calibration the right way.

[size=14.6667px]Also I've noticed that the drone sometimes is slightly yawing CCW on his own.

[size=14.6667px]Any clue what can cause this issue?

[size=14.6667px]Any help is appreciated.

Did you tried ugraded firmware to latest and after perform IMU and compass calibrations?

Hey Mantas, sorry for the late response. The data has been forwarded to our engineers for review, we'll come back as long as there is an update.

Update: Mantas, do you mount any accessories on the aircraft? Is the compass status green after the compass calibration? If not and the issue appears frequently, I'm afraid that you have to send the unit in: https://www.dji.com/support Sory about this.

Hi Susan,

Nope there's no accessories on aircraft, and the compass status is green after calibration.
