Unexpected behavior with DroneCan and GPS_auto_config?

ArduCopter Copter 4.4
1

First, let’s start with my hardware
FC is a MATEK H743 wing V3
Firmware: Copter 4.4.3
2 Here3 GPS on CAN splitter
Quad H frame

The issue I have these settings for enabling uavcan
CAN_D1_PROTOCOL 1
CAN_P1_DRIVER 1
GPS_AUTO_CONFIG 1 <---- The issue
GPS_TYPE 9
GPS1_TYPE 9

I get GPS status 3 on both modules and a 3D fix but if I set GPS_AUTO_CONFIG 2 then GPS
status is 1 and I get GPS: No Fix. Am I missing something? And is it safe to assume that I do not have a CAN_D2 DRIVER or CAN_D2_PROTOCOL because I am running them through a can splitter?

Thanks in advance for responding

Hi Fred,

Did you ever get this sorted? I’m having a similar issue. Getting “GPS: No fix” even though the GPS unit (Holybro M9N Drone CAN) has a 3D fix.
