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:
> CONNECT OK
> AT+CIPSENDMP-C 0 QRG/M9iLIp+XEVajAB2v8t
> JIBS2rw2cub6ssu5QY4C7Q== xxxxxx
> DATA ACCEPT:63
> Any thoughts? I haven't yet looked
> communications of my working module to compare.
> Does anyone have a firmware or tutorial that
> sends a fixed sms message to test the cellular
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.
