I'm using an APM2 from the first batch and am, having some trouble with the compass/magnetometer enable setting. The board set has been flying and I'm just investigating the compass as prep to moving it to a quad.
I can check Planner's enable box for the compass and that changes MAG_ENABLE to "1". So, I write params to the APM2, then disconnect and reconnect Planner. After re-reading the params, MAG_ENABLE is still set to 1.
Now I power down the plane and reconnect the battery. Next, reconnect Planner and it reads the params. MAG_ENABLE is now "0", and Planner's compass checkbox is unchecked.
When I use the CLI it tells be that "Compass Initialization Failed!" for an HMC5883L device.
Is this an RTFM, a bug or a hardware fault?
Thanks.
