Hi Bill
re- “Hi Richard, the current version of APM Planner (2.0.14) doesn’t work with 3.2-rcx - it doesn’t calibrate both the compasses (previous 3.1 only used a single compass). There’s a fix in for the next release:”
A fellow flyer posted the above with regards to an issue I have trying the latest beta of copter which is it keeps failing compass pre-arm checks. I have the latest copter beta 3.2 rc7 but still have the pre-arm check problem even after many compass re-cal and pixhawk re-boots. I’ve had two separate gps / external compasses on. The compass id’s are correct as per Randy so I’m at a dead end. Is there any chance it’s an issue with APM P?? I do have he latest beta APM P. Just trying to rule out possibilities. Thank you.
