I am trying to use Navio2 in an octocopter but I am having huge problems with the compasses (EKF magnetometer innovation is bigger than 1 during almost the whole flight). Could you please tell me some models of external compasses that work with Navio2? I used HMC5983 in the past, but it is not longer available.
I’m afraid I can’t recommend any specific models of the compatible external compasses for Navio2. Hopefully, some of our users who used the compasses besides HMC5983 would be able to help you with it.
