I’m facing a problem with the Pixhawk 3 Pro. I’m running Firmware V1.9.2. The GPS is the one from your Pixhaw 3 Pro Pack. The Calibration of the sensors works fine, in the Summary everything looks fine but if I try to arm, I get the message that there is no valid data from compass 0.
In the analysis IMU and IMU3 mag values are all zero. The only valid data comes from IMU2.
Screenshot from the analysis:
