Hi
From an other user I saw that MissionPlanner 1.3.70 build 1.3.7374.10358 had a section with Compass Priority on the Setup/Mandatory Hardware/Compass page, see below.
But on later builds it has disappeared again.
Any chance that this is something that will be implemented ?
I guess you have to connect to a latest dev firmware rover or copter to get it…
UPDATE : Your flight/rover controller firmware must support the COMPASS_PRIO1_ID parameter, if this parameter exists then MP enables the extended compass calibration page you show above.
