Hello Forumers,
I have plugged in an external GPS/compass combo into the UART port of Navio2. When I start arducopter, I get the following error:
pi@navio:~ $ sudo ./arducopter-quad
Raspberry Pi 2/3 with BCM2709!
Init APM:Copter V3.4-dev (e391da7a)
Free RAM: 262144
FW Ver: 120

� Q}�AK8963: Onboard compass detected
HMC5843: Could not detect version
HMC5843: External compass not detected
COMPASS INIT ERROR
� Q��Init Gyro*� Q� **
I tried using the standard and latest build from github for arducopter-quad, same result.
The reason I upgraded to external compass is that the Navio2 compasses are not stable on my build.
Many thanks for your help!
