PixHawk and Marvelmind Integration


We want to use auto mode indoors without GPS using beacon of Marvelmind.
We followed this manual.

So we got 3D FIX. But at the same time, the EKF turns red. I don’t know if this is normal.
The main problem is that the propeller doesn’t spin.
When i try to arming, the phrase ‘Arm: Compass not healthy’ appears.
But the motor has a melody when it is arming. However, the motor does not spin when throttle is raised up. And the screen is also DISARMED.

Can I get some help on this?
Thank you…
