+CMGS - Send Message
+CMGS: <mr>[,<scts>]
where
<mr> - message reference number.
<scts> - TP-Service Centre Time Stamp in Time String Format.
Note: if message sending fails for some reason, an error code is reported.
Note: concatenated SMS is not supported
Note: In text mode, the maximum length of an SMS depends on the used coding
scheme: It is 160 characters if the 7 bit GSM coding scheme is used, and 140
characters according to the 8 bit GSM coding scheme.
Note: SIO consumes all SMS commands and also the text entered by user. So C-AT
doesnot receive any SMS commands until SIO is fixed.
AT+CMGS=?
Test command resturns the OK result code.
Note To avoid malfunctions is suggested to wait for the +CMGS: <mr> or +CMS
ERROR: <err> response before issuing further commands.
