3GPP TS 27.005 AT COMMANDS FOR SMS AND CBS
HSPA+ AT Commands Reference Guide 138
Notes PDU Mode
„
The DCD signal is in ON state while PDU is given.
„
The echoing of given characters back from the TA is controlled by echo command E.
„
The PDU is hexadecimal format (each octet of the PDU is given as two IRA character long hexadecimal number)
and given in one line.
„
When the length octet of the SMSC address (given in the PDU) equals zero, the SMSC address set with command
+CSCA is used; in this case the SMSC Type‐of‐Address octet is not present in the PDU.
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:
where
‐ message reference number; 3GPP TS 23.040 TP‐Message‐Reference in integer format.
„
If message sending fails for some reason, an error code is reported.
„
Ensure no other SIM interacting commands are issued during the command execution, which may take several
seconds.
Parameters and Values Text Mode
Destination address, string type represented in the currently selected character
set. See +CSCS.
Type of destination address.
129 Number in national format.
145 Number in international format. Contains the "+".
After command line is terminated with , the device responds sending a four
character sequence prompt:
(IRA 13, 10, 62, 32)
After this prompt text can be entered. Format the text as follows:
„
If current (see +CSMP) indicates that GSM03.38 default
alphabet is used and current (see +CSMP) indicates that
3GPP TS 23.040 TP‐User‐Data‐Header‐Indication is not set, then
ME/TA converts the entered text into GSM alphabet, according to
GSM 27.005, Annex A; backspace can be used to delete last
character and carriage returns can be used; after every
entered by the user the sequence
is sent to the TE.
„
If current (see +CSMP) indicates that 8‐bit or UCS2 data
coding scheme is used or current (see +CSMP) indicates that
3GPP TS 23.040 TP‐User‐Data‐Header‐Indication is set. Entered
text consists of two IRA character long hexadecimal numbers
which ME/TA converts into 8‐bit octet (for example the ‘asterisk’
is entered as 2A (IRA50 and IRA65) and this is converted to an
octet with integer value 0x2A)
