I'm running V3.4-rc4 on a BBBMINI. I have both an external compass (HMC5843) and a compass on the MPU9250 inertial sensor (AK8963). The software automatically names the HMC5843 as Compass 1, and the AK8963 as Compass 2.
Several months ago (on an earlier build), I had a few flights where the HMC5843 stopped functioning, and the AK8963 automatically showed up as Compass 1. The problem is that it then had the wrong offsets, and more importantly, had the wrong orientation. (The HMC5843 has orientation ROTATION_ROLL_180, and the AK8963 has orientation ROTATION_NONE). This causes some erratic behavior, especially in Loiter mode.
My external compass seems to be functioning again, and I would rather not replace it unless it starts happening again. I would prefer the AK8963 appeared as Compass 1, so if the HMC5843 disappears again, then the Compass 1 configuration is still good.
Is there any way I can do this? I've included a screenshot of my setup, if anyone has suggestions on how to change it.
Thanks!
