Library Description

Library provides function for controlling device pins, and function for sendint AT commands over UART communication.

Key functions:

• void lteiot3_send_cmd ( uint8_t *cmd_buf ) - Function for sending commands to device.
• void lteiot3_set_pin_on ( uint8_t pin_state  - Function for setting on pin state.

Examples description

The application is composed of three sections :

• System Initialization - Initialization of UART MODULE and additional pins
• Application Initialization - Turns on device and sends initial commands
• Application Task - Checks some device parameters by sending AT commands

void application_task ( )
{
    lteiot3_send_cmd( &AT_CGATT[0] );
    Delay_ms( 5000 );
    log_buffer();
    lteiot3_send_cmd( &AT_CEREG[0] );
    Delay_ms( 5000 );
    log_buffer();
    lteiot3_send_cmd( &AT_CSQ[0] );
    Delay_ms( 5000 );
    log_buffer();
}

Other mikroE Libraries used in the example:

• Conversions
• UART

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.
