4G LTE 2 Data-NA Click

4G LTE 2 Click - Data (for North America) is a compact add-on board providing a secure-cloud multi-band solution offering universal connectivity and reliable performance. This board features the LARA-R6401D, the world’s smallest LTE Cat 1 module from u-blox with coverage for North American region and a built-in MQTT client, representing a data-only solution. Equipped with familiar AT commands set over the UART interface, USB interface, and Network and Status indicators, the LARA-R6401D also has a comprehensive certification scheme, multi-band and multi-mode capabilities providing excellent flexibility, except for the support of voice/audio application.

  • Type : UART type

Software Support

We provide a library for the 4G LTE 2 Data-NA Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for 4G LTE 2 Data-NA Click driver.

Standard key functions :

Example key functions :

Example Description

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

The demo application is composed of two sections :

Application Init

Initializes the driver, restarts the module and tests the communication.

void application_init ( void )
{
log_cfg_t log_cfg;
c4glte2datana_cfg_t c4glte2datana_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
c4glte2datana_cfg_setup( &c4glte2datana_cfg );
C4GLTE2DATANA_MAP_MIKROBUS( c4glte2datana_cfg, MIKROBUS_1 );
if ( UART_ERROR == c4glte2datana_init( &c4glte2datana, &c4glte2datana_cfg ) )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
c4glte2datana_process( );
c4glte2datana_clear_app_buf( );
app_buf_len = 0;
app_buf_cnt = 0;
// Check communication
error_flag = c4glte2datana_rsp_check( );
c4glte2datana_error_check( error_flag );
log_info( &logger, " Application Task " );
}

Application Task

Application task is split in few stages:

  • C4GLTE2DATANA_CONFIGURE_FOR_NETWORK:

    Sets configuration to device to be able to connect to the network.

  • C4GLTE2DATANA_WAIT_FOR_CONNECTION:

    Waits for the network registration indicated via CREG URC event and then checks the connection status.

  • C4GLTE2DATANA_CONFIGURE_FOR_EXAMPLE:

    Sets the device configuration for sending SMS or TCP/UDP messages depending on the selected demo example.

  • C4GLTE2DATANA_EXAMPLE:

    Depending on the selected demo example, it sends an SMS message (in PDU or TXT mode) or TCP/UDP message. By default, the TCP/UDP example is selected.

void application_task ( void )
{
switch ( example_state )
{
{
if ( C4GLTE2DATANA_OK == c4glte2datana_configure_for_network( ) )
{
}
break;
}
{
if ( C4GLTE2DATANA_OK == c4glte2datana_check_connection( ) )
{
}
break;
}
{
if ( C4GLTE2DATANA_OK == c4glte2datana_configure_for_example( ) )
{
example_state = C4GLTE2DATANA_EXAMPLE;
}
break;
}
{
c4glte2datana_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"

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.4GLTE2DataNA

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. UART terminal is available in all MikroElektronika compilers.
