[Ovmsdev] SIM808 not communicating

[Michael Balzer]

Hi Tom,

your diag log looks normal until the module starts 
to send something.

It even succeeds with the TCP connect, but the 
connection closes as soon as it sends:

> OK

> CONNECT OK
> AT+CIPSENDMP-C 0 QRG/M9iLIp+XEVajAB2v8t

Are you sure the SIM account has enough SMS & data 
volume? Does the SIM work normally in a mobile phone?

You can use the diag mode to send an SMS manually. 
Note: the 808 does not echo LF, only CR.

Regards
Michael
