Hello everyone !

Some time ago, I encountered an issue that I’m now reporting. If anyone can help me, I’d be very grateful. I was conducting a short flight when I experienced an issue with the Here4’s compass. During the flight, the messages ‘EKF3 IMU0 Switching to compass 1’ and then ‘EKF3 IMU0 Switching to compass 0’ appeared repeatedly until the end of the flight.

We know the Here4 has had chronic compass issues.
My question is: when it lost both Here4 compasses, did it use the cube’s compass? Even the compass cube’s was deactivated?

Our Setup:
Cube orange+
Kore Carrier Board
Dual Here4
25kg TOW

I can’t access your log, I think you need to set access to “Anyone with the link”

Without looking at the log: if the two Here4 compasses were set to mag1 and mag2, and COMPASS_USE3 was set to 0, then the autopilot would never use the cube’s compass.
