Hi @Nathan-Ni ,

Can you check ekf2 status via the NSH terminal?

I wonder if you have a magnetometer or not? Flight Core has no on board mag and, by default, ekf2 doesn't initialize without a mag and then you will get no attitude (roughly).

@modaltb Thank you for your answer, it is true that the problem is caused by the lack of magnetic compass.
