Bad AHRS

Posted by Mike Mac on June 3, 2015 at 3:03pm

Attached are the logs of a power up with "Bad AHRS" message. It usually clears but this time it did not. This is a new Pixhawk direct from 3DR and has never been flown.

What should I do to resolve this message?

Do I have something configured incorrectly?

Is it safe to fly?

I have 3.3.0 airplane firmware loaded.

    An accel calibration again has solved that msg for us, also the Pixhawk/plane must be kept absolutely still for 10-15 secs after boot otherwise that msg pops up
