5.12. Send message +CMGS

The <address> field is the address of the terminal network to whom the

message is sent ; <exitmethod> is ^Z : ASCII 26. The text can contain all

existing character except ^Z.

Example of use :

Application to GSM AT+CMGS="+33146290800"<CR>

Hello, how are you ?^Z

Send a message in text

mode

GSM to application +CMGS : <mr>

Successful transmission

Application to GSM AT+CMGS=<length><CR>

<pdu>^Z

Send a message in PDU

mode

GSM to application +CMGS : <mr>

Successful transmission

The message reference <mr> which is returned back to the application is

allocated by the GSM module. This number begins with 0 and is incremented

by one for each outgoing message (successful and failure case) ; it is cyclic

on one byte (0 follows 255).

Note : this number is not a storage number - outgoing messages are not

stored.

5.13. Set Text Mode Parameters +CSMP

This command shall be used to select value for the <vp>, <pid>, the

<dcs>. The application must send the following command :

AT+CSMP=<fo>, <vp>, <pid>,<dcs>

In text mode <vp> is coded only in "relative" format. This means one

octet (see document [4] for more details).

Application to GSM AT+CSMP? current values

GSM to application +CSMP: 0,0,0,0

no validity period

dcs = PCCP437 alphabet

( 8 bits -> 7 bits )

Application to GSM AT+CSMP=16,32,64,244 validity period = 32

dcs = GSM 8 bits alphabet

GSM to application OK command correct
