Library Description
The library carries generic command parser adopted for AT command based modules. Generic parser.
Key functions:
Examples Description
Example demo application waits for the call. After the call is received the parser will get a hangup call.
This code snippet shows how generic parser should be properly initialized.
Before initialization, the module must be turned on and in addition to this, the hardware
flow control should also be turned on.
// MODULE POWER ON c4glte_hfcEnable( true ); c4glte_modulePower( true ); // MODULE INIT c4glte_cmdSingle( "AT" ); c4glte_cmdSingle( "ATE0" ); c4glte_cmdSingle( "AT+IFC=2,2" ); c4glte_cmdSingle( "AT+CMGF=1" );
Along with the demo application, timer initialization functions are provided. Note that 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.
The full application code, and ready to use projects can be found on our Libstock page.

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.
