I followed this instruction and successfully completed the steps until the second flight test. However, for normal test setup, when I tried to change the setting:

  1. Set AHRS_EKF_TYPE = 3 to use EKF3

I encountered a warning message stating ‘AHRS requires visual odometry.’ Have I missed something? Thank you for your assistance!

I solved this problem.

I just wait a time and then it was disappeared. But I checked parameters again.
