Possible Bug? Compass Calibration Failing on Mission Planned

Posted by Andy Hornsey on July 12, 2014 at 11:42am

Hi All, 

I have just upgraded to mission planner 1.3.6 build 1.1.5306.14681 and I can not get the compass calibration to work. I am building a new copter and this is a show stopper for me since you can't arm without compass calibration (quite sensibly! )

I just tried on my old copter which used to calibrate fine and its not possible there too ... can you help?

Please see attached screenshot for error details.

PC is running Windows 8.1

Thanks,

Andy

      Same problem here. Also, I cannon arm the APM any more.  "Error: Arm message rejected by MAV"

    @Andy,

    Please describe the symptoms of not being able to calibrate the compass with MP 1.3.6.

    Have you made sure COMPASS_EXTERNAL is set to 1 and COMPASS_PRIMARY is set to 0 (External)?

      Tom, COMPASS_PRIMARY only exists as a parameter in trunk, not in the earlier versions of the code

        @Craig,

        You are right. I am using a beta 2 version of ArduRover2 v2.46.
