[Ovmsdev] Random Crashes

[Mark Webb-Johnson]

Tom,

I think I’ve found the issue (or at least one of them). Just caught a similar crash here.

The CREG (network registration status went 5->2 (roaming -> searching), but the simcom driver didn’t handle that. It should have torn down the PPP. Can simply repeat by unplugging the antenna.

I’ll try to look at some edge cases today, and improve the handling.

Regards, Mark.

I'm assuming the ovms has rebooted each time the graph goes back to zero. The actual connectivity seems pretty good as there aren't many jumps in the graph where data was not being updated on the server, the most obvious one being just before 4am.
