how to calibrate the compass !!???
one day to calibrate... and z axle offset is always failed !
I replace the GPS to test, but the offsets are the same. is it an EB3 problem ? what is the correct config ?
APM documentation says :
Pixhawk/PX4 + Compass = Compass #1 external / Compass #2 internal
I tried to "rotation roll 180" and "rotation yaw 180" on compass#1
thanks for your help.
