We have in our possession a GPS Here with a GPS2 type pin connector (6 pins). We are trying to configure ardupilot parameters in order to use GPS2 only.
Our params are:
GPS_PRIMARY = 1
GPS_TYPE = 0
GPS_TYPE2 = 1
GPS_AUTO_SWITCH = 0
SERIAL4_PROTOCOL = 5
On mission planner HUD it displays both GPSs with a red color:
GPS: NO GPS
GPS2: 3D FIX
Is this normal? Can we completely remove GPS from main screen and only keep GPS2 since we don’t have dual GPS? Is the red color a concern?
EDIT: We use a Pixhawk Cube Black.
