Issue with Arming via QGroundControl when EKF2_MAG_TYPE is Set to None

[Ang]

I am experiencing an issue with arming my drone in different modes (Stabilized, Hold, and Manual) when the ekf2_mag_type is set to none . The preflight error message I receive is “Preflight Fail: Compass Sensor 0 missing.”

From the flight review logs, it’s evident that the ekf2_mag_type value is set to 5 and the attempted arming mode was Stabilized.

Additionally, when I checked the sensor_mag topic using the MAVLink console in QGroundControl with the command listener sensor_mag , the output was “never published.”

I have come across a discussion suggesting that without a heading source, arming might not be possible.

EKF2 GPS fusion without heading source

About As of currently in PX4, I found that the GPS fusion won’t start in EKF2 unless there are one of the following heading estimate sources: Dual antenna GPS for heading information External Vision Magnetometer We were interested in a way to allow GPS fusion even without heading estimate sensor because we wanted to exclude using magnetometer for simplifying the sensor set used onboard a flying wing, intended for navigating to coordinates. Here’s a log for the test where EKF2 was not able to…

But the drone operates normally when controlled via a Futaba remote controller, which suggests the hardware itself is functioning correctly.

Is there a way to configure QGroundControl (QGC) to arm the drone just like when using a Futaba remote controller?
