Hi there. I hope anyone recognize this issue.

Just upgraded from P3A to P4P. I'm having troubles after compass calibration. I get green light after horizontal calibration, but after vertical calibration it keeps flashing red/yellow and yes even far away from any magnetic field... I did my IMU-calibration and I still get this compass error. Flying is no problem and homepoint is normally saved. No problems there. Please help...

Any metal on your person?  Rings, magnetic money clip, large belt buckle, etc?

Nothing more than when I flew my P3A...

I had a magnetic money clip that would mess up my P4 compass calibration and not my P3P, so while that may not be the issue......eliminate all the possible causes and see if it will calibrate.

I will calibrate it naked

It has more to do with the ground on which you perform the calibration, best to do it in a grass field, far away from concrete.

Maybe its your magnetic personality..;-)

I had the same thing happen with a brand new P4 Pro right out of the box.  It would not calibrate no matter what I tried.  The app was reporting Compass #2 disconnected.  In the end I sent it back to DJI and they replaced the entire bird free of charge.  The replacement P4P calibrates just fine.
