Reversed compass when the controller rotated by 180 deg

[maciek252]

Hi,

I’m flying an F765-Wing controller running the ArduPlane. The mavlink telemetry is transmitted by a Crossfire link to a mobile phone running QGC. The controller is rotated by the 180 degrees yaw, and the appropriate parameters are set so that in the Mission Planner the geographical directions are shown correctly. However, on QGC (both daily build and the version from Google Play) these directions are reversed, so N is where S should be etc. Is this a problem of QGC or ArduPlane?

Create a GitHub issue. Save a telemetry log which shows the issue. Link to the log in the issue and then I can replay it and see what is going on.

The similar issue (cannot switch to Position control, compass reversed by 180 deg outdoor, but correct indoor) happens in our drone after updating to 1.13.3
There is our log and the detailed description of the problem .
Could you help us check the log?
I solved it, thanks, updated by 5/19/2023

We really appreciate your help and time

Cannot use Position control mode, and the heading is 180 degree wrong (reversed compass) (wrong outdoor but correct indoor)

When trying to switch “Position control” mode, it shows the error "Switch to mode “Position control” is currently not possible . check for a valid position estimate " After recalibrating, upload firmware, and reboot, the error disappears.
