I previously had aero optical flow working, but now it is not. Any ideas on how to debug this?

Hi Jeffrey95,
Thank you for your interest in the Intel Aero drone.
Please let me look into it and I will get back to you later.

Hi Jeffrey95,
You should try re-calibrating the sensors and make sure that in QGroundControl they are using the following parameters:
EKF2_AID_MASK = 3 (use GPS + use optical flow)
EKF2_HGT_MODE = 2 (range sensor)
Did you make any changes deriving from the guide or crashed/found physical issues with the drone or camera connections before or after the error started occurring?
Regards,
Alexandra
