When trying to init APM Planner 2.0 with ardurover (or else) firmware will install OK with initial setup, but config/tuning - Mandatory setup - Compass will not allow "APM with 3DR GPS/Compass.
Click on “compass enable” does not change anything.
Compass is plugged OK on AMP
Terminal gives this info:
“Compass initialisation failed”
Impossible to have compass ON with “compass on” command in setup mode.
Any idea welcome !
