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.
