I want to avoid magnetic by disabling mag (compass).
After setting the parameter
CAL_MAG0_ID to '0' (reset to default) in QGC and reconnected, but the compass value is displayed as below image.
I want to know the compass is operating or not.
In addition, I removed the
magnometerCheck function in
PreflightCheck.cpp, but the the error message is displayed ("Unable to takeoff, vehicle position not know.")
Please let me know about this problem.
