[Ovmsdev] Still having major comms problems

[Mark Webb-Johnson]

Matt,

The only thing I can suggest is if you have a USB-RS232 adaptor (or a laptop with RS232), when you get in a state the module is not responding to SMS and has not GPRS connection, plug in to the DIAG port of the module and log the output. The DIAG port is a tap into the communications between the modem and the MCU. It operates at 9600baud N-8-1.

Regards, Mark.

By comparison, mine resets an average of 15 times a day (as I have really poor coverage at home).
