LTE IoT 4 Click Board

We provide a library for the LTE IoT 4 Click Board™ and a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on the mikroE Github account.

Library Description

This library contains an API for the LTE IoT 4 Click Board™ driver.

Key Functions

• void lteiot4_cfg_setup ( lteiot4_cfg_t *cfg ); - Config Object Initialization function.
• LTEIOT4_RETVAL lteiot4_init ( lteiot4_t *ctx, lteiot4_cfg_t *cfg ); - Initialization function.
• void lteiot4_default_cfg ( lteiot4_t *ctx ); - Click the Default Configuration function.

Example Description

This example reads and processes data from the LTE IoT 4 Click Board™.

void application_task ( void )
{
    if ( app_connection_status == WAIT_FOR_CONNECTION )
    {
        //CEREG
        log_info( &logger, " Check connection  " );
        lteiot4_send_cmd( &lteiot4, LTEIOT4_CMD_CHECK_CONNECTION );
        app_error_flag = lteiot4_rsp_check();
        lteiot4_error_check( app_error_flag );
        Delay_ms( 500 );
        
        //CEREG
        log_info( &logger, " Check network status  " );
        lteiot4_send_cmd( &lteiot4, LTEIOT4_CMD_CHECK_REGISTARTION );
        app_error_flag = lteiot4_rsp_check();
        lteiot4_error_check( app_error_flag );
        Delay_ms( 500 );
        
        //CEREG
        log_info( &logger, " Check signal quality  " );
        lteiot4_send_cmd( &lteiot4, LTEIOT4_CMD_SIGNAL_QUALITY );
        app_error_flag = lteiot4_rsp_check();
        lteiot4_error_check( app_error_flag );
        log_printf( &logger, "-------------------------------rn" );
        Delay_ms( 5000 );
    }
    else
    {
        log_info( &logger, "CONNECTED TO NETWORKrn" );
        log_printf( &logger, "-------------------------------rn" );
        //CCLK
        log_info( &logger, " Set Time " );
        lteiot4_send_cmd( &lteiot4, LTEIOT4_CMD_SET_DUMMY_CLOCK );
        app_error_flag = lteiot4_rsp_check();
        lteiot4_error_check( app_error_flag );
        log_printf( &logger, "-------------------------------rn" );
        Delay_ms( 3000 );
        
        for(;;)
        {
            //XTEMP
            log_info( &logger, " Check Temperature " );
            lteiot4_send_cmd( &lteiot4, LTEIOT4_CMD_CHECK_TEMPERATURE );
            app_error_flag = lteiot4_rsp_check();
            lteiot4_error_check( app_error_flag );
            Delay_ms( 500 );
            //CCLK
            log_info( &logger, " Check Time " );
            lteiot4_send_cmd( &lteiot4, LTEIOT4_CMD_CHECK_CLOCK );
            app_error_flag = lteiot4_rsp_check();
            lteiot4_error_check( app_error_flag );
            log_printf( &logger, "-------------------------------rn" );
            Delay_ms( 5000 );
        }
    }
}

The complete application code and ready-to-use projects can be installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on the mikroE Github account.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.LTEIoT4

Additional Notes and Information

Depending on the development board you are using, you may need a USB UART Click Board™, USB UART 2 Click Board™ or RS232 Click Board™ 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.

MIKROSDK

The LTE IoT 4 Click Board™ ™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
