Hi, I am currently using QGroundControl and I am trying to set up my calibration for my Pixhawk. But this error keeps showing up when I am trying to calibrate my Compass Sensor. The error is as follows, Retry Calibration (Unable to fit mag 0)
I’m getting the same error with a Pixhawk 6C
make px4_fmu-v6c_default. (Built on 9/22/2022)
Try going to Analyst Tools, and click Mavlink Console. Note the Pixhawk 6C uses: the ist8310 magnetometer. I’m seeing bad register events and bad transfer events. Try the commands below at the nsh> prompt.

For me this was caused by MATEKSYS Digital AirSpeed Sensor (ASPD-DLVR, CAN, I2C & UAVCAN) plugged into the 12c port without removing the two resistors to pit it into 12c mode. Looks like PX4 does not support this airspeed sensor mode in DroneCAN mode. I want to keep the sensor in CAN mode so I replaced it with FPVDrone PX4 Differential Airspeed Pitot Tube + Pitot Tube Airspeedometer Airspeed Sensor for Pixhawk PX4 Flight Controller. https://www.amazon.com/dp/B09XQ3SCDK?psc=1&ref=ppx_yo2ov_dt_b_product_details. Sort of sucks, but it works now.
