I have a here3 on a cube orange and it has been working great for about 6 months and suddenly its not working. I wanted to test some settings so I first saved my existing settings and then played around. I didnt like what I did so I loaded the param file. Everything else is working but now and the settings appear to be exactly as I had them (which was working). However, now when I power up the Here3 blinks the LED’s for about 4 seconds and then goes dead. I double checked the settings and they appear to be fine. If I unplug it from the CAN port nd then put it back it does the same thing, it just blinks blue for a few seconds and then nothing. I tried to connect to it via the UAVCAN config section in mission planner but it doesn’t see the GPS. I am at a loss as to what could cause this?
Try setting the boot delay to 5000 (5 seconds).
Thank for the tip! I actually traced it down to a faulty connector and once I replaced that its working normally again.
