Software Support

We provide a library for the LTE_IoT Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

The application is composed of three sections :

• System Initialization - Initializes all necessary GPIO pins, UART used for the communcation with LTE IOT 2 module and UART used for infromation logging
• Application Initialization - Initializes driver, power on module and sends few command for the default module configuration Create UDP socket and sending message to UDP socket.

This code snippet shows how generic parser should be properly initialized. Before intialization module must be turned on and additionaly to that hardware flow control should be also

Commands :

• Command : AT+CMEE=2 - Enables the cellular module to report verbose error result codes
• Command : AT+CGATT? - Verifies the SARA-R4 module is attached to the network.
• Command : AT+CEREG? - Verify the network registration status.
• Command : AT+COPS=0 - Register the module on the network
• Command : AT+COPS? - Read the operator name
• Command : AT+USOCR=17 - Create a UDP socket.
• Command : AT+USOST=0,"IP address",port,number character,"message" - Connecting and storing text on the server.
• Command : AT+USORF=0,number character - Reading the message from the server
• Command : AT+USOCL=0 - Closing the socket.

// MODULE POWER ON
    lteiot_hfcEnable( true );
    lteiot_modulePower( true );

// MODULE INIT
    lteiot_cmdSingle( &_LTEIOT_AT[0] );
    lteiot_cmdSingle( &_LTEIOT_ATE1[0] );
    lteiot_cmdSingle( &_LTEIOT_AT_CMEE[0] );
    lteiot_cmdSingle( &_LTEIOT_AT_CGATT[0] );
    lteiot_cmdSingle( &_LTEIOT_AT_CEREG[0] );
    lteiot_cmdSingle( &_LTEIOT_AT_COPS[0] );
    lteiot_cmdSingle( &_LTEIOT_AT_COPS_1[0] );
    lteiot_cmdSingle( &_LTEIOT_AT_USOCR[0] );
    lteiot_cmdSingle( &_LTEIOT_AT_USOST[0] );
    lteiot_cmdSingle( &_LTEIOT_AT_USOCL[0] );

Alongside with the demo application timer initialization functions are provided. Note that timer is configured acording to default develoment system and MCUs, changing the system or MCU may require update of timer init and timer ISR functions.

The full application code, and ready to use projects can be found on our LibStock page.

Other mikroE Libraries used in the example:

• String
• Conversion

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
