+CMGS - Send Message SELINT 0 / 1
AT+CMGS=<da>
[,<toda>] Execution command sends to the network a message.
Parameters:
<da> - destination address, string type.
<toda> - type of destination address
129 - number in national format
145 - number in international format (contains the "+")
After command line is terminated with <CR>, the device responds sending a
four character sequence prompt:
<CR><LF><greater_than><space> (IRA 13, 10, 62, 32)
After this prompt text can be entered; the entered text should be formatted
as follows:
- if current <dcs> (see +CSMP) indicates that GSM03.38 default alphabet is
used and current <fo> (see +CSMP) indicates that GSM 03.40 TP-User-
Data-Header-Indication is not set, then ME/TA converts the entered text
into GSM alphabet, according to GSM 07.05, Annex A; backspace can be
used to delete last character and carriage returns can be used.
- if current <dcs> (see +CSMP) indicates that 8-bit or UCS2 data coding
scheme is used or current <fo> (see +CSMP) indicates that GSM 03.40
TP-User-Data-Header-Indication is set, the entered text should consist of
two IRA character long hexadecimal numbers which ME/TA converts into
8-bit octet (e.g. the ‘asterisk’ will be entered as 2A (IRA50 and IRA65)
and this will be converted to an octet with integer value 0x2A)
Note: the DCD signal shall be in ON state while text is entered.
Note: the echoing of entered characters back from the TA is controlled by
echo command E
To send the message issue Ctrl-Z char (0x1A hex).
To exit without sending the message issue ESC char (0x1B hex).
If message is successfully sent to the network, then the result is sent in the
format:
+CMGS: <mr>
where
<mr> - message reference number.
Note: if message sending fails for some reason, an error code is reported.
Note: care must be taken to ensure that during the command execution,
which may take several seconds, no other SIM interacting commands are
