Unhealthy AHRS troubleshooting

I get the “Unhealthy AHRS” message a lot from my sailboat, although it works fine as far as I can tell.

What values trigger this warning in mission planner?

What should I look at in the tlog or dataflash log to debug this?

I looked through the documentation but could not find an answer, please send a link if I missed something. Thanks!

Hi. I am struggling with a similar issue for a boat. Have you managed to find a solution?

Thanks.

I don’t have a systematic method for tracking down what is triggering the message.

At some point I upgraded to a M9N GPS, recalibrated the compass and the accelerometers, and it has been happy lately.

Recalibrate the accelerometers and compass will probably solve this.

I’ve recalibrated the accelerometers and compass many times, but not a permanent fix. Does anyone happen to know of one?
