V2.00 : Now using ADL. The +TELESTART command disables/enables the application.
V2.10 : Sample behaviour updates
V3.00 : Multi-Uart support ; MultiApp library support ; New Q2501 product

Dependencies

This sample depends on the following libraries :

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

Application Description

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

AT+TELESTART (Telemetry start/stop command)

Command	Answers
AT+TELESTART?	+TELESTART: <state> OK
AT+TELESTART=?	+TELESTART: (0-1) OK
AT+TELESTART= <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 tele_init() function. The start/stop entry points linked to the +TELESTART command are the tele_start() and tele_stop() functions.

This application checks some GPIO states every 3 seconds. On a state change, it sends a SMS report to the number set by the application (via the +TEL command) :

AT+TEL (Phone number set command)

Command	Answers
AT+TEL=?	+TEL: (20) OK
AT+TEL?	+TEL: <number> OK
AT+TEL= <number>	WRONG PARAMETER or OK

Parameter	Values range	Description	Default value
number	20	Destination phone number for GPIO SMS report	mandatory

This command is always available. When number is set in IDLE state, the SMS report is sent. When it is set out of IDLE state, the SMS will be sent as soon as the Application returns to IDLE state.
The read GPIO are set by the +IOSET command :

AT+IOSET (GPIO settings command)

Command	Answers
AT+IOSET=?	+IOSET: (1-2047) OK
AT+IOSET?	+IOSET: <settings> OK
AT+IOSET= <settings>	WRONG PARAMETER or OK

Parameter	Values range	Description	Default value
settings	1-2047	Gpio settings, according to current product see below). On any programmed input state change, the SMS report is sent.	0
