Library Description
The library carries a generic command parser adopted for AT command based modules. Generic parser.
Key functions:
gsm2_cmdSingle - Sends a provided command to the module.
gsm2_setHandler - Handler assignation to the provided command.
gsm2_modulePower - Turns on the module.
Examples Description
The example demo application waits for the cal, and after the call is received the parser will get hang up.
This code snippet shows how a generic parser should be properly initialized. Before the initialization, the module must be turned on, and in addition to this, the hardware flow control should also be turned on.
Commands:
void applicationInit()
{
// MODULE POWER ON
gsm2_hfcEnable( true );
gsm2_modulePower( true );
// MODULE INIT
gsm2_cmdSingle( "AT" );
gsm2_cmdSingle( "ATE0" );
gsm2_cmdSingle( "AT+IFC=2,2" );
gsm2_cmdSingle( "AT+CMGF=1" );
}
Along with the demo application, timer initialization functions are provided. Note that the timer is configured according to the default development system and MCUs, changing the system or MCU may require an update of timer init and timer ISR functions.

Additional notes and information
Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
