Almost a year to date of replacing my FlightAware Pro Stick Plus, I’m getting failures again. This time, I left the RiPi running and just unplugged/replugged the Stick and it reboots OK. Past/present failures seem to correspond with summer heat. The unit is in the hot attic but not in direct sunlight.
Stick a fan blowing over it, like a PC fan or USB fan might not make drastic improvement but least it gives it some airflow around it to dissipate heat, my set up is in the loft (attic) and did the same but using an RTL-SDR with added PC heatsink
