[Ovmsdev] v3 hardware disconnecting from v2 server

Fri Mar 16 09:48:48 HKT 2018

Probably the most useful output, at the time when the modem couldn’t recover would be:

simcom status
network status
module memory
module tasks

I’m only running with the DEMO vehicle module, Server V2, Wifi AP, and SIMCOM. No GPS enabled. The network seems stable to me (although I am getting one general crash about once a day).

Regards, Mark.

Today, with the second half of your changes, it didn't seem to reconnect by itself. Unfortunately I haven't had a data logger on it with your improvements so I don't have a lot of information about what is wrong. I went and investigated it's current state this evening and while the CLI user interface was working well, nothing simcom related was being logged. I guess there's something that wedges that task.

I tried two OVMS antennas with no luck. I've attached the log. I've testing a Spark m2m simcard, and the last few days have been using that. I have access to their m2m monitoring facility, that reported a 3 minute session with 1457 bytes up and 5321 bytes down. After failing to reconnect after rebooting with the button, I put the 2degress consumer simcard back in and it connected immediately. You can see the last thing I do in the log is change the apn. I haven't included the log of the working session.
