Hello everyone
Due to magnetic interference with our CAN GPS (2x Holybro DroneCAN H-RTK F9P Helical) which is located too close to the ESCs / wires, we want to use additional compasses (DroneCAN RM3100) which are located on the landing gear of our multicopter. In order to have redundancy, each “set” (GPS + compass) is connected to a dedicated CAN port (Cube Orange on an Airbot Systems Mini carrier board) using a CAN hub.
The problem with this solution is that only 3 (random) compasses are displayed in the compass section in mission planner (2xGPS and 1x compass or 2x compass and 1x GPS etc), but never all 4 at once (which would give me the chance to disable the unwanted ones).
Now I have 2 questions:
- Why are not all CAN devices shown in the compass section?
- Is it possible to disable the internal compasses of the CAN-GPS so that they do not occupy the CAN bus at all? There seem to be some parameters stored on the GPS module itself, such as COMPASS_USE, which can be set to 0 but will not change anything.
Thanks in advance!
