I'm having a battle with my compasses. I use pixhawk clone and M8N GPS with compass.
I'm unable to find orientation setting, where I will not have EKF compass variance errors.
I think that this is not mag interference problem because this happens when disarmed.
I've disasembled external GPS/compass puck and there are following axis markings:
z axis O------->
| y axis
My APM configuration is in the attachments, and also example values when facing north.
Do I have faulty compass? or I've tried wrong Orientation settings?
