Hi I am using Cube orange Plus with Here4 (with latest FW) on my quad setup. The copter flies very well and has been flown for more than 20 hrs. Recently it developed an issue of showing no CAN compass. The GPS satellites are available and I get 3D fix but no UAVCAN compass avail. Last time I faced an issue similar to this with Here4, it was resolved with FW upgrade. Unfortunately, this time, no response whatsoever. To check whether CAN ports are OK. I swapped here 4 with here3 and everything works perfectly. Please guide in this matter. How can I resolve this issue. Regards,
