happy New Year , one and all :) !
now upgraded from 3DR APM2.5 to a PixHawk FC.
Have 3D (GPS) lock.
The compass calibration is the same as with the ol'good APM, the difference is I see two coordinates rotating and taking the points.
The values obtained are good and in the range written in the WiKi.
Now I'm unsure how to assign the external compass, so the PixHawk uses the external compass in the GPS module?
1- After the calibration success (more than 2000pts) when I move the PixHawk FC, the compass in Mission Planner moves an shows the orientation.
But if I move only the GPS/compass module, (holding the FC still) nothing happens - no movement in MP.
The GPS/compass module config' is compass 1, the internal compass is nr. 2.
I'm wondering what is wrong.
2- Another strange effect is, that with nothing connected to the PixHawk, only linked to the PC via USB, I get a compass variance error (in MP) from the internal FC compass.
I hope somebody could enlighten me what I have to do to correct this compass problem. Thank you :)
