I guess I need to revive this thread as I'm still having issues with a v3.3 module in my Corvette. What I see is that things work normally for 1-2 days and then I start getting flatbed alerts because the module doesn't detect when the car is "on". As a test I swapped in my dev module (vintage 2018) and it worked flawlessly for about a month. I swapped the v3.3 module back a few weeks ago and was only able to make one day's worth of trips without flatbed alerts and then they were back. And I filled up last night but the v2 server shows me a 33%. What kind of logging can I enable that would be helpful? My modules currently have 3.3.003-2-gd00de6c0 More recently I started having issues with network registration and gnss reception; at least every few days both cars will transition from RegisteredRoaming to Searching and then back to RegisteredRoaming. They also transition from 12 satellites in view to no satellites in view and back to 12 satellites in view. For the cellular connection I might buy that a local cell tower is out of service and/or maybe my signal strength is too low. But for the gnss I can't see why this would happen, especially given that I have a satellite antenna in the garage, under the same tar-and-gravel roof as the cars, that I used for ntp synchronization (a u-blox ZED-F9T based receiver tracking four constellations...) and it never misses a beat. Not sure if I have two different issues here or if one is related to the "SIM7600 Registration Denied" thread. Craig
