ArduPlane

Not correct working Vectornav with Ardupilot.
All parameters are set correctly according to the instructions.
AHRS_EKF_TYPE = 11 (External AHRS)
EAHRS_TYPE = 1 (VectorNAV)
SERIALx_PROTOCOL to “36” (AHRS) and SERIALx_BAUD to “115”

Tried firmware 4.5.0, 4.3.7 and others. Writes an error:
Failed to register gyro id …
GPS working fine.
And other - not work

What could be the problem?

I’m having the same issue with VN-300 connected to BlueRobotics Navigator flight controller on a BlueBoat running ardurover.

Have you made any progress?
