Hi, I just bought a Pixhawk 2.4.8 and accessories on AliExpress, items seem to be working. But Mission Planner still uses the internal compass on the PX board even though I checked all the boxes and params in choosing external compass as the main compass.
When I try to calibrate it, the GPS compass is functional, as well as the internal compass. However when I go back to “Flight Data” section of Mission Planner, it still uses the internal compass as the main compass.
I am not sure how to fix this, please guide me through
