BLE 6 Click

BLE 6 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 reads and processes data from BLE 6 Clicks.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.BLE6

Example Key Functions

• ble6_cfg_setup Config Object Initialization function.

void ble6_cfg_setup ( ble6_cfg_t *cfg );

• ble6_init Initialization function.

err_t ble6_init ( ble6_t *ctx, ble6_cfg_t *cfg );

• ble6_set_response_handler Set response handlers function.

void ble6_set_response_handler ( void ( *handler )( uint8_t* ), ble6_hdl_t driver_hdl );

• ble6_set_handlers Set handlers function.

void ble6_set_handlers ( ble6_handler_t event_handler, ble6_handler_t eve_hdlr );

• ble6_parser_rsp Response parser function.

void ble6_parser_rsp ( ble6_t *ctx, ble6_rsp_t *response );

Application Init

Initialization driver enables - UART, sets handlers initialize and enable UART interrupt, reset and configures BLE module, initialize BLE Server Profile ( Services and Characteristics ).

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    ble6_cfg_t ble6_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.

Application Task

The app starts by checking the system ready flag and returns the Bluetooth device address. After that, the chain of commands creates Primary Server Profiles: Device Information, Generic Access and Custom Service to Start Advertising. For transmit messages, we use Generic Access Primary Service with Write permissions of the characteristic Element. In this example, transmitting message is limited to a maximum of 11 characters. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void ) 
{
    ble6_event_handler( );
    
    while ( device_connected_flag ) 
    {
        int32_t cnt = ble6_generic_read( &ble6, rx_response, PROCESS_BUFFER_SIZE );
        Delay_ms ( 100 );
        if ( ( ble6_strncmp( rx_response, hci_le_serverwrite_event, 1 ) == 0 ) && ( cnt > 13 ) ) 
        {
            ble6_response_handler( );
        }
    }
}

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.
