Compassmot invalid command

I tried running the compassmot command from the MP terminal setup menu. It said that the command was invalid. Has this been function been deprecated?

try running
this will list the valid commands.
as im pretty sure compassmot is still there.

Did you type setup first followed by compassmot

Thanks for the suggestions. I did two things differently: I upgraded to 3.0.1 firmware and replaced the telemetry radio connection with the USB cable. Now it works. Not sure which of those two things made the difference. The reading was 122%. I’ve decided to simply add the external compass rather than relocating my APM 2.5+.
