V2.00 : Now using ADL ; The +CMONSTART command disables/enables the application.
V3.00 : Multi-Uart support ; MultiApp library support

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+CMONSTART (Call Monitoring start/stop command)

Command	Answers
AT+CMONSTART?	+CMONSTART: <state> OK
AT+CMONSTART=?	+CMONSTART: (0-1) OK
AT+CMONSTART= <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 cmon_init() function. The start/stop entry points linked to the +CMONSTART command are the cmon_run() and cmon_stop() functions.

This application provides unsolicited responses in order to inform the external application of the current call operations. The syntax of this unsolicited response is the following (Wavecom OpenAT Call Monitor) :

+WOCM: <ID>,<dir>,<status>,<mode>,<mpty>,<number>,<type>,<alpha>,<exit_cause>

All parameters are similar to the +CLCC response, except the <exit_cause> parameter. This one is equal to 0, except when the call is released : this parameter is then the error returned by the +CEER command. A new +WOCM unsolicited response is displayed when the <status> parameter has changed for this call <ID>. In addition with the +CLCC <status> values, the status value takes the value "6" when the call is released.

A log system is provided to save in Flash Memory the last unsolicited +WOCM responses for each call ID. This system is managed by the +WOCM command :

AT+WOCM (Call Monitoring Logs control command)

Command	Answers
AT+WOCM?	+WOCM: <mode> , <logs> OK
AT+WOCM=?	+WOCM: (0-3) , (1-7) OK
AT+WOCM= <mode> , <ID>	+CME ERROR: 3 or OK

Parameter	Values range	Description	Default value
mode	0-3	0 : to disable the log saving system (default) 1 : to enable the log saving system 2 : to read the saved log for provided call ID 3 : to delete the saved log for provided call ID	mandatory
ID	1-7	Log ID to read or delete (for modes 2 and 3)	NA
logs	00-3E	hexadecimal string, each bit (from 0 to 6, for each call ID) is set if a call log was saved for this call ID. For example : "01" : a log is saved in Flash Memory for call ID 1 "0A" : a log is saved in Flash Memory for call IDs 2 and 4	NA
