LTE Cat.1 3 AUX Click

LTE Cat.1 3 Click (for Australia) is a compact add-on board for reliable 4G wireless communication. This board features the EG91AUXGA-128-SGNS, an LTE Cat 1 IoT module that meets the 3GPP Release 11 standard from Quectel. It supports multiple wireless standards, including LTE-FDD, WCDMA, and GSM, ensuring broad network compatibility. Key features include multi-band LTE support (B1/B2/B3/B4/B5/B7/B8/B28/B66), RX diversity for bands B1, B2, B5, and B8, and multi-constellation GNSS (GPS, GLONASS, BeiDou/Compass, Galileo, QZSS). It also integrates a 16-bit mono audio codec for voice functionality with support for CTIA standard headphones.

Click library

  • Author : Stefan Ilic
  • Date : Mar 2024.
  • Type : UART type

Software Support

We provide a library for the LTE Cat.1 3 AUX 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 LTE Cat.1 3 AUX Click driver.

Standard key functions :

Example key functions :

  • ltecat13aux_write_register This function writes a data byte into the selected register address.
    err_t ltecat13aux_write_register ( ltecat13aux_t *ctx, uint8_t reg, uint8_t data_in );
  • ltecat13aux_max9860_cfg This function is used to set basic config for MAX9860 of LTE Cat.1 3 AUX Click board.
  • ltecat13aux_send_sms_pdu This function sends text message to a phone number in PDU mode.
    err_t ltecat13aux_send_sms_pdu ( ltecat13aux_t *ctx, uint8_t *service_center_number, uint8_t *phone_number, uint8_t *sms_text );

Example Description

Application example shows device capability of connecting to the network and

sending SMS, TCP/UDP messages, calling the selected number, or getting GNSS location using standard "AT" commands.

The demo application is composed of two sections :

Application Init

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

or GNSS location.

void application_init ( void )
{
log_cfg_t log_cfg;
ltecat13aux_cfg_t ltecat13aux_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
ltecat13aux_cfg_setup( &ltecat13aux_cfg );
LTECAT13AUX_MAP_MIKROBUS( ltecat13aux_cfg, MIKROBUS_1 );
if ( UART_ERROR == ltecat13aux_init( &ltecat13aux, &ltecat13aux_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
ltecat13aux_process( );
ltecat13aux_clear_app_buf( );
Delay_ms ( 1000 );
if ( 0 == ltecat13aux_get_ri_pin( &ltecat13aux ) )
{
ltecat13aux_start_up( &ltecat13aux );
error_flag = ltecat13aux_rsp_check( LTECAT13AUX_RSP_RDY );
ltecat13aux_error_check( error_flag );
}
// Restart device
#define MIN_FUN_DEVICE "0"
error_flag = ltecat13aux_rsp_check( LTECAT13AUX_RSP_OK );
ltecat13aux_error_check( error_flag );
#define FULL_FUN_DEVICE "1"
error_flag = ltecat13aux_rsp_check( LTECAT13AUX_RSP_OK );
ltecat13aux_error_check( error_flag );
// Check communication
error_flag = ltecat13aux_rsp_check( LTECAT13AUX_RSP_OK );
ltecat13aux_error_check( error_flag );
log_info( &logger, " Application Task " );
}

Application Task

Depending on the selected demo example, it sends an SMS message

(in PDU or TXT mode) or a TCP/UDP message, calls the selected number or gets GNSS location.

void application_task ( void )
{
switch ( example_state )
{
{
if ( LTECAT13AUX_OK == ltecat13aux_cfg_for_network( ) )
{
}
break;
}
{
if ( LTECAT13AUX_OK == ltecat13aux_check_connection( ) )
{
}
break;
}
{
if ( LTECAT13AUX_OK == ltecat13aux_cfg_for_example( ) )
{
example_state = LTECAT13AUX_EXAMPLE;
}
break;
}
{
ltecat13aux_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.LTECat13AUX

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.
