This sample depends on the following libraries :

MultiApp
This MultiApp sample library provides start/stop mechanism to handle several running ADL applications.

Application Description

This application provides unsolicited indications to inform the external application that a formatted SMS has been received.

As this application uses the MultiApp library, the following start/stop command has to be used to control the application execution.

AT+AUTOSTART (Secured Control start/stop command)

Command	Answers
AT+AUTOSTART?	+AUTOSTART: <state> OK
AT+AUTOSTART=?	+AUTOSTART: (0-1) OK
AT+AUTOSTART= <state>	+CME ERROR: 3 or OK

Parameter	Values range	Description	Default value
state	0-1	The current application running state. This parameter is stored in non-volatile memory.	0

The init entry point sent to the MultiApp library is the smsauto_init() function. The start/stop entry points linked to the +AUTOSTART command are the smsauto_run() and smsauto_stop() functions.

This application provides unsolicited responses informing the external application that a formatted SMS has been received. The SMS text may be formatted as follows (for example) :

#TEST#value#/TEST#text text#VALUE#123456789#/VALUE#

The Tags are delimitted by the '#' character. The Tags' name are defined in the cTagTab[] const string table in the appli.c file, and are case sensitives. A Tag name may not include the '#' character.

All the text between the "#tag#" and "#/tag#" expressions is considered as a value for this Tag. This text may not include the '#/' character sequence.

All the text between an ending tag "#/tag#" and another starting tag "#tag2#" is ignored and lost.

If a SMS format error occurs, the preceding well-formatted data are treated, but the following data are lost.

For this example, the syntax of the unsolicited response is the following (Wavecom OpenAt SMS Tag) :

If at least one Tag is well formatted, the SMS is deleted from SIM, otherwise it remains in SIM memory.
The provided "appli.c" file uses two example tags : "TEST" and "VALUE".
