I’m having trouble getting Here 3+ stable. I have two GPS receivers installed on my drone. The first is Here 3+ and the second is Ublox F9P. I would like the primary GPS to be F9P because it is more accurate, and the secondary one would be Here 3+. The problem is that if I set GPS_AUTO_SWITCH=4 in Mission Planner, when F9P catches a better 3D Fix than Here 3+, Here 3+ freezes and the LEDs glow solid yellow and Mission Planner hangs. It looks as if Here 3+ could only be a primary GPS.
Do you have any idea how to change the priority of Here 3+?
