Library Description

The library carries generic command parser adopted for AT command based modules. Generic parser.

Key functions:

• c4glte_cmdSingle - Sends the provided command to the module.
• c4glte_setHandler - Handler assignation to the provided command.
• c4glte_modulePower - Turns on the module.

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.

• The first command negotiates baud rate with the module.
• The second command turns echo off.
• The third command enables hardware flow control - necessary in case of UART polling.
• The fourth command sets up the default message format.

// 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.
