EFK error maybe compas orientation wrong?

Hey guys,

i had a hard time finding the right orientation for my external compas


i could not find any information on the orientation so i just try and error the thing…
it only worked with the “onboard” pixhawk compas unchecked “use that compas”.

then i went for a first few flights, and pids were crap but the rest was ok.

but in the log is an EFK error? any ideas?

thanks!

Hey,

I am a beginner so this might be useless, but cant you USB to Mission Planner and see when the compass points to N, make the front of the craft point North and that is the orientation it should be installed?
