LTE IoT 5 click

LTE IoT 5 Click is add-on board with compact and cost-effective secure cloud multi-band module solution designed for IoT applications. This board features the SARA-R510M8S, a cellular module that supports LTE-M/NB-IoT* bands with integrated high performance standard precision M8 GNSS receiver for global position acquisition from u-Blox.

Click library

• Author : Luka Filipovic
• Date : Dec 2020.
• Type : UART type

Software Support

We provide a library for the LTEIoT5 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 LTEIoT5 Click driver.

Standard key functions :

• Config Object Initialization function.

  void lteiot5_cfg_setup ( lteiot5_cfg_t *cfg );

• Initialization function.

  LTEIOT5_RETVAL lteiot5_init ( lteiot5_t *ctx, lteiot5_cfg_t *cfg );

• Click Default Configuration function.

  void lteiot5_default_cfg ( lteiot5_t *ctx );

Example key functions :

LTE IoT 5 data reading function.

err_t lteiot5_generic_read ( lteiot5_t *ctx, char *data_buf, uint16_t max_len );

Send command function.

void lteiot5_send_cmd ( lteiot5_t *ctx, char *cmd );

LTE IoT 5 power on.

void lteiot5_power_on ( lteiot5_t *ctx );

Examples Description

This example reads and processes data from LTE IoT 5 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;  /**< Logger config object. */
    lteiot5_cfg_t lteiot5_cfg;  /**< Click config object. */

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.

        }
    }
}

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 "vip.mobile"\ PHONE_NUMBER_TO_MESSAGE "999999999"

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.LTEIoT5

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.
