Library Description

The library covers all the necessary functions to control LTE Cat. 1 click board. Library carries generic command parser adopted for AT command based modules.

Key functions:

• void ltecat1_cmd_single ( uint8_t *p_cmd ) - Sends provided command to the module function.
• uint16_t ltecat1_set_handler( uint8_t *p_cmd, uint32_t timeout, ltecat1_handler_t p_handler ) - Handler assignation to the provied command function.
• void ltecat1_module_power ( uint8_t power_state ) - Enables or disables module power function.

Examples description

The application is composed of three sections :

• System Initialization - Initializes all necessary GPIO pins, UART used for the communcation with GSM module and UART used for infromation logging
• Application Initialization - Initializes driver, power on module and sends few command for the default module configuration
• Application Task - running in parallel core state machine and checks for call flag. If call detected parser will hang up call.

void application_task ( )
{
    char rsp_com[ 50 ] = {0};

    // GSM
    // CORE STATE MACHINE
    ltecat1_process( );

    if (0 != call_flag)
    {
        ltecat1_cmd_single( <ECAT1_ATH[ 0 ] );
        Delay_ms( 3000 );

        call_flag = 0;
    }
}

• void ltecat1_default_handler( uint8_t *rsp, uint8_t *ev_args ) - Default handler.

Other mikroE Libraries used in the example:

• UART
• Conversion
• String

Additional notes and informations

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.
