I have a Pixhawk cube orange with 4.0.3 and the GPS works only on CAN1. The GPS is attached and the parameters were changed to take the GPS input from CAN1 port but the carrier board doesnt detects a GPS it doesnt hold its position in position hold mode or loiter mode.
Mission planner telemetry shows that there is 3D fix and locked but the copter doesnt hold its position.
After callibrating it again the lights turned to cyan blue solid and still it shows 3D fix but no results.
can someone tell me with what is to be done in the params and also what if i want the GPS to work on GPS1 port. I am using Here2 GPS
