Click library

  • Author : Stefan Ilic
  • Date : Sep 2021.
  • Type : UART type

Software Support

We provide a library for the BLE6 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for BLE6 Click driver.

Standard 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 );

Example key functions :

  • 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 );

Example Description

This example reads and processes data from BLE 6 clicks.

The demo application is composed of two sections :

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.

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );

    ble6_display_log( );
    Delay_ms ( 100 );

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

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( );
        }
    }
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

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

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. UART terminal is available in all MikroElektronika compilers.
