Library Description

Library provides functions for sending commands to the device, and for controlling included GPIO.

Key functions:

• void nbiot2_send_cmd( char *cmd ) - Function for sending data to the device
• void nbiot2_hw_reset ( void ) - Function for restarting the device

Examples description

The application is composed of three sections :

• System Initialization - Initialization of UART module and additional pins
• Application Initialization - Enables UART Interrupt, resets the device, and configures the device
• Application Task - Checks a few parameters for device connection

void application_task ( )
{
    nbiot2_send_cmd( &CGATT[ 0 ] );
    Delay_ms( 5000 );
    write_buff(  );

    nbiot2_send_cmd( &CEREGG[ 0 ] );
    Delay_ms( 5000 );
    write_buff(  );

    nbiot2_send_cmd( &CSQ[ 0 ] );
    Delay_ms( 5000 );
    write_buff(  );
}

Additional Functions :

• void write_buff ( ) - Function for writing response buffer

Other mikroE Libraries used in the example:

• 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.
