LTE Cat.1-EU Click

LTE Cat.1-EU Click is a Click board™ based on Thales Cinterion® ELS61 wireless module that delivers highly efficient Cat 1 LTE connectivity for M2M IoT solutions offering seamless fall back to 2G and 3G networks. The best in class solution enables M2M optimized speeds of 10Mbit/s download and 5Mbit/s uplink making it ideal for the vast number of M2M and industrial IoT applications that are not dependent on speed but that requires the longevity of LTE networks, while still providing 3G and 2G connectivity to ensure complete population and geographic coverage as LTE rolls out.

  • Author : Stefan Ilic
  • Date : Jun 2021.
  • Type : UART type

Software Support

We provide a library for the LTECat1EU 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 LTECat1EU Click driver.

Standard key functions :

Example key functions :

Example Description

This example reads and processes data from LTE Cat.1-EU clicks.

The demo application is composed of two sections :

Application Init

Initializes driver and wake-up module and sets default configuration for connecting device to network.

void application_init ( void ) {
log_cfg_t log_cfg;
ltecat1eu_cfg_t ltecat1eu_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
Delay_ms ( 1000 );
// Click initialization.
ltecat1eu_cfg_setup( &ltecat1eu_cfg );
LTECAT1EU_MAP_MIKROBUS( ltecat1eu_cfg, MIKROBUS_1 );
err_t init_flag = ltecat1eu_init( &ltecat1eu, &ltecat1eu_cfg );
if ( init_flag == UART_ERROR ) {
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
log_info( &logger, " Power on device... " );
ltecat1eu_power_on( &ltecat1eu );
// CFUN - restart ME
app_error_flag = ltecat1eu_rsp_check( RSP_SYSSTART );
ltecat1eu_error_check( app_error_flag );
// AT
app_error_flag = ltecat1eu_rsp_check( RSP_OK );
ltecat1eu_error_check( app_error_flag );
Delay_ms ( 500 );
// ATI - product information
app_error_flag = ltecat1eu_rsp_check( RSP_OK );
ltecat1eu_error_check( app_error_flag );
Delay_ms ( 500 );
// CGMR - firmware version
app_error_flag = ltecat1eu_rsp_check( RSP_OK );
ltecat1eu_error_check( app_error_flag );
Delay_ms ( 500 );
// COPS - deregister from network
app_error_flag = ltecat1eu_rsp_check( RSP_OK );
ltecat1eu_error_check( app_error_flag );
Delay_ms ( 500 );
// CGDCONT - set sim apn
app_error_flag = ltecat1eu_rsp_check( RSP_OK );
ltecat1eu_error_check( app_error_flag );
Delay_ms ( 500 );
// CFUN - full funtionality
app_error_flag = ltecat1eu_rsp_check( RSP_OK );
ltecat1eu_error_check( app_error_flag );
Delay_ms ( 500 );
// COPS - automatic mode
app_error_flag = ltecat1eu_rsp_check( RSP_OK );
ltecat1eu_error_check( app_error_flag );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
// CEREG - network registration status
app_error_flag = ltecat1eu_rsp_check( RSP_OK );
ltecat1eu_error_check( app_error_flag );
Delay_ms ( 500 );
// CIMI - request IMSI
app_error_flag = ltecat1eu_rsp_check( RSP_OK );
ltecat1eu_error_check( app_error_flag );
Delay_ms ( 500 );
app_buf_len = 0;
app_buf_cnt = 0;
app_connection_status = WAIT_FOR_CONNECTION;
log_info( &logger, " Application Task " );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
}

Application Task

Waits for device to connect to network and then sends SMS to selected phone number.

void application_task ( void ) {
if ( app_connection_status == WAIT_FOR_CONNECTION ) {
// CGATT - request IMSI
app_error_flag = ltecat1eu_rsp_check( RSP_OK );
ltecat1eu_error_check( app_error_flag );
Delay_ms ( 500 );
// CEREG - network registration status
app_error_flag = ltecat1eu_rsp_check( RSP_OK );
ltecat1eu_error_check( app_error_flag );
Delay_ms ( 500 );
// CSQ - signal quality
app_error_flag = ltecat1eu_rsp_check( RSP_OK );
ltecat1eu_error_check( app_error_flag );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
} else {
log_info( &logger, "CONNECTED TO NETWORK" );
// SMS message format - text mode
ltecat1eu_send_cmd_with_parameter( &ltecat1eu, "AT+CMGF", "1" );
app_error_flag = ltecat1eu_rsp_check( RSP_OK );
ltecat1eu_error_check( app_error_flag );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
for( ; ; ) {
log_printf( &logger, "> Sending message to phone number...\r\n" );
app_error_flag = ltecat1eu_rsp_check( RSP_OK );
ltecat1eu_error_check( app_error_flag );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
}
}
}

Note

In order for the example to work, user needs to set the phone number and sim apn to which he wants to send an SMS Enter valid data for the following macros: SIM_APN and PHONE_NUMBER_TO_MESSAGE.

E.g.

  • SIM_APN "vipmobile"
  • 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.LTECat1EU

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.
