NanoBeacon Click

NanoBeacon Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

This example demonstrates the use of NanoBeacon Click board by setting the Eddystone URI advertisement to Click boards webpage.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.NanoBeacon

Example Key Functions

• nanobeacon_cfg_setup Config Object Initialization function.

void nanobeacon_cfg_setup ( nanobeacon_cfg_t *cfg );

• nanobeacon_init Initialization function.

err_t nanobeacon_init ( nanobeacon_t *ctx, nanobeacon_cfg_t *cfg );

• nanobeacon_set_advertising This function sets the device MAC address, interval and advertising raw data.

err_t nanobeacon_set_advertising ( uint8_t *mac_address, uint16_t interval, uint8_t *adv_raw_data, uint8_t len );

• nanobeacon_load_adv_to_ram This function loads advertising data to RAM.

err_t nanobeacon_load_adv_to_ram ( nanobeacon_t *ctx );

• nanobeacon_start_advertising This function starts the advertising.

err_t nanobeacon_start_advertising ( nanobeacon_t *ctx );

Application Init

Initializes the driver and logger.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    nanobeacon_cfg_t nanobeacon_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.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.
    nanobeacon_cfg_setup( &nanobeacon_cfg );
    NANOBEACON_MAP_MIKROBUS( nanobeacon_cfg, MIKROBUS_1 );
    if ( UART_ERROR == nanobeacon_init( &nanobeacon, &nanobeacon_cfg ) )

        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Every 10 seconds, it restarts and configures the device for advertisement with the Eddystone URI beacon format set to Click boards webpage: https://www.mikroe.com/click

void application_task ( void )
{
    // The device MAC address for advertisement
    static uint8_t mac_address[ 6 ] = { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06 };

    // Eddystone advertisement raw data
    static uint8_t eddystone_adv_raw[ ] = 
    { 
        0x03, // Length of Service List
        0x03, // Param: Service List
        0xAA, 0xFE, // Eddystone ID
        0x12, // Length of Service Data
        0x16, // Service Data
        0xAA, 0xFE, // Eddystone ID
        0x10, // Frame type: URL

        'm','i','k','r','o','e', 
        0x00, // .com/
        'c','l','i','c','k' 
    };
    log_printf( &logger, "\r\n Restart device\r\n" );
    nanobeacon_restart_device ( &nanobeacon );
    
    while ( NANOBEACON_OK != nanobeacon_check_communication ( &nanobeacon ) )
    {
        log_error( &logger, " Check communication." );
        Delay_ms ( 1000 );
    }
    log_printf( &logger, " Configure device for advertisement\r\n" );
    if ( NANOBEACON_OK != nanobeacon_set_advertising ( mac_address, 1000, eddystone_adv_raw, 
                                                       sizeof( eddystone_adv_raw ) ) )
    {
        log_error( &logger, " Set advertising." );
    }

    if ( NANOBEACON_OK != nanobeacon_load_adv_to_ram( &nanobeacon ) )
    {
        log_error( &logger, " Load data to RAM." );
    }
    
    log_printf( &logger, " Start advertising\r\n" );
    if ( NANOBEACON_OK != nanobeacon_start_advertising ( &nanobeacon ) )
    {
        log_error( &logger, " Start advertising." );
    }    
    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

During advertising, the Click board should appear as an Eddystone URI beacon on the BLE Scanner application.

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
