Greetings, I have gone through the Here3 manual and install setup on my Hexarotor running Arducopter V4.0.7. In the UAVCAN I can only find one of the brand new Here3 units. I have updated this to ID #26. The other HERE3 does not appear. In the Compass screen 2 UAVCAN devices show up on the same BUS with different ID’s (26 – one I manually set) and (124 – default that I cannot connect to). Do I have a faulty HERE3 Unit?
Try BRD_BOOT_DELAY,5000 and see if that helps. It was specifically put in to allow CAN devices to boot before the FC, so they were ready to go when the CAN bus started working.
