LTE Cat.1 2 Click

LTE Cat.1 2 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Software Support

Example Description

Application example shows device capability of connecting to the network and sending SMS, TCP/UDP messages or calling the selected number using standard "AT" commands.

Example Libraries

Example Key Functions

• ltecat12_cfg_setup Config Object Initialization function.

  void ltecat12_cfg_setup ( ltecat12_cfg_t *cfg );

• ltecat12_init Initialization function.

  err_t ltecat12_init ( ltecat12_t *ctx, ltecat12_cfg_t *cfg );

• ltecat12_max9860_cfg LTE Cat.1 2 MAX9860 configuration function.

  err_t ltecat12_max9860_cfg ( ltecat12_t *ctx );

  void ltecat12_send_cmd ( ltecat12_t *ctx, uint8_t *cmd );

• ltecat12_send_sms_pdu LTE Cat.1 2 send SMS in PDU mode.

  err_t ltecat12_send_sms_pdu ( ltecat12_t *ctx, uint8_t *service_center_number, uint8_t *phone_number, uint8_t *sms_text );

Application Init

Sets the device configuration for sending SMS, TCP/UDP messages or calling the selected number.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    ltecat12_cfg_t ltecat12_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    ltecat12_cfg_setup( &ltecat12_cfg );
    LTECAT12_MAP_MIKROBUS( ltecat12_cfg, MIKROBUS_POSITION_LTECAT12 );
    if ( UART_ERROR == ltecat12_init( &ltecat12, &ltecat12_cfg ) )
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );
        for ( ; ; );
    }
    
    ltecat12_process( );
    ltecat12_clear_app_buf( );
 
    // Restart device
    #define RESTART_DEVICE "1,1"
    ltecat12_send_cmd_with_params( &ltecat12, LTECAT12_CMD_CFUN, RESTART_DEVICE );
    error_flag = ltecat12_rsp_check( LTECAT12_RSP_SYSSTART );
    ltecat12_error_check( error_flag );
    
    // Check communication
    ltecat12_send_cmd( &ltecat12, LTECAT12_CMD_AT );
    error_flag = ltecat12_rsp_check( LTECAT12_RSP_OK );
    ltecat12_error_check( error_flag );
    
    log_info( &logger, " Application Task " );
    example_state = LTECAT12_CONFIGURE_FOR_NETWORK;
}

Application Task

Depending on the selected demo example, it sends an SMS message (in PDU or TXT mode) or a TCP/UDP message or calls the selected number.

void application_task ( void )
{
    switch ( example_state )
    {
        case LTECAT12_CONFIGURE_FOR_NETWORK:
        {
            if ( LTECAT12_OK == ltecat12_cfg_for_network( ) )
            {
                example_state = LTECAT12_WAIT_FOR_CONNECTION;
            }
            break;
        }
        case LTECAT12_WAIT_FOR_CONNECTION:
        {
            if ( LTECAT12_OK == ltecat12_check_connection( ) )
            {
                example_state = LTECAT12_CONFIGURE_FOR_EXAMPLE;
            }
            break;
        }
        case LTECAT12_CONFIGURE_FOR_EXAMPLE:
        {
            if ( LTECAT12_OK == ltecat12_cfg_for_example( ) )
            {
                example_state = LTECAT12_EXAMPLE;
            }
            break;
        }
        case LTECAT12_EXAMPLE:
        {
            ltecat12_example( );
            break;
        }
        default:
        {
            log_error( &logger, " Example state." );
            break;
        }
    }
}

Note

In order for the examples to work, user needs to set the APN and SMSC (SMS PDU mode only) of entered SIM card as well as the phone number (SMS mode only) to which he wants to send an SMS. Enter valid values for the following macros: SIM_APN, SIM_SMSC and PHONE_NUMBER_TO_MESSAGE.

Example:

• SIM_APN "internet"
• SIM_SMSC "+381610401"
• PHONE_NUMBER_TO_MESSAGE "+381659999999"

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
