[Ovmsdev] 1.3.1

Do you remember what code the lights were flashing?

I checked mine, and it was bizarre. Green LED was flashing 1 (GPRS up and connected), and red LED was off (no errors found). But, when I connected a PC to the DIAG port (thanks to v2 hardware I can do this now when the box is running), the modem responded just fine but there was no comms between the modem and the PIC. As the LEDs were flashing, the PIC was definitely running. It seems that the RS232 port was just dead on the PIC side. A hardware reset brought it back alive.

I guess I'll have to add a timer to the NET driver code for data last received on the modem port. If nothing is received in a few minutes, then time to reset everything.

Regards, Mark.

However, later today I drove into the city where coverage is excellent and OVMS did not reconnect.  After hard reset OVMS was able to connect.  If there is any other information I can supply, please let me know.  I updated firmware to 1.3.5 a couple days ago.

>>> If the car is in an area of poor / no cellular coverage, then drives out to an area of good coverage, does OVMS connection re-establish? In particular, if you previously saw a situation where you had to unplug-then-plugin the module to hard-reset it, does that still happen? If realise that this will take longer to know, as it was very rare.
