Pixhawk 4 PREFLIGHT FAIL: COMPASS SENSORS INCONSISTENT

Hi!

I require your help regarding a problem I’m encountering.

Description:
After the Pixhawk 4 has been successfully configured, the preflight check is also successful. However, if the Pixhawk 4 is turned off and restarted, the preflight check will always fail (PREFLIGHT FAIL: COMPASS SENSORS INCONSISTENT) and we will need to reconfigure the entire Pixhawk 4.

Hardware concerned:
Pixhawk 4 Holybro
Telemetry Radio V3 Holybro
Pixhawk 4 GPS Module Holybro
Pixhawk 4 Power Management Board

Software concerned:
PX4 v1.9.0
QGroundControl

Troubleshooting steps already taken:
COM_ARM_MAG parameters changed to 0.5 Gauss

Thank you so much in advance for your help!

Hi Florian,

We never played with the Pixhawk 4 before and we do not sell this particular version (looking to sell it in the near future).
However you can follow the Compass calibration HERE.

Here are some more links that can be useful:
