Two of my four Pixhawks are giving abnormally high compass offsets. I have attached four pictures, each is labeled with board type and number. First is with a PX4 FMU with IO v1.6, and offsets are withing reason. The other three boards are Pixhawks, only one of which is yielding reasonable offsets. All the boards are bare, were calibrated with USB (attempted wirelessly as well) and calibrated in the same environment. No ferrous metals were in close proximity during calibrations. Calibration routines were ran three to four times on the two boards in question.
Are you using the internal Pixhawk/PX4 compass or the one in the GPS/Compass Module?
I am using the internal compass on each. Thanks
