Software Support

We provide a library for the 4G_LTE Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

Library carries generic command parser adopted for AT command based modules. Generic parser

Key functions :

  • c4glte_cmdSingle - Sends provided command to the module
  • c4glte_setHandler - Handler assignation to the provied command
  • c4glte_modulePower - Turn on module

Examples Description

Example demo application waits for the call, after call is received the parser will get hangup call.

This code snippet shows how generic parser should be properly initialized. Before intialization module must be turned on and additionaly to that hardware flow control should be also

Commands :

  • First command negotiates baud rate with module
  • Second command turns echo off
  • Third command enables hardware flow control - necessary in case of UART polling
  • Fourth command setup default message foramt
// 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" );

Alongside with the demo application timer initialization functions are provided. Note that timer is configured acording to default develoment system and MCUs, changing the system or MCU may require update of timer init and timer ISR functions.

The full application code, and ready to use projects can be found on our LibStock page.

Other mikroE Libraries used in the example:

  • String
  • Conversion

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.
