Compass Calibration Unexpected Error

Hi all,

I am having a problem to calibrate the compass (external and internal). I am using Arduplane 3.8.4 and Mission Planner 1.3.52

As soon as I clicked ‘OK’ to start the live calibration, the calibration window stopped and show there was unexpected error. I tried both by connecting Pixhawk 2.1 to USB and through telemetry but the result was the same. I checked the status window and parameter list, it seemed like Pixhawk 2.1 detected the external compass and the internal compass.

Really hope to solve this problem soon.

Are you able to test on another pc, as that seems like a mission planner bug. Other I suggest you reinstall the software and make sure you run it as administrator.
