GPS Yaw was not used

ArduCopter

Hi, all.

I set EK3_SRC1_Yaw to GPS with Copter-4.6.3 on CubeOrange,
but the GPS Yaw was not reflected.

Just to be sure, I turned off USE for Compas1 and 2.

The symptom was no matter what orientation the aircraft was placed in and started up, the Yaw was 0 degrees.

Also, the GPS Yaw was pointing in the correct direction.

It seems that even when I set the EK3 Yaw source to GPS on the Copter,
it doesn’t use it, and instead uses the gyro.

On the other hand, the GPS Yaw was definitely used on the Rover.

What about you ?

Provide a log file, please.

I set it up before flying and checked its behavior.
I didn’t ARM so there are no flash logs,
but there should be a telemetry log.

I’ll look for it later.

Set LOG_DISARMED,1 and capture 10-15 minutes of disarmed state in an open/outdoor setting.
