Bluetooth Click

Bluetooth 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.

• Date : Jun 2020.
• Type : UART GPS/GNSS type

Software Support

Example Description

This example reads and processes data from Bluetooth Clicks.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Bluetooth

Example Key Functions

• bluetooth_cfg_setup Config Object Initialization function.

void bluetooth_cfg_setup ( bluetooth_cfg_t *cfg );

• bluetooth_init Initialization function.

err_t bluetooth_init ( bluetooth_t *ctx, bluetooth_cfg_t *cfg );

• bluetooth_enter_command_mode The function enter the command mode of the RN-41 Bluetooth module on Bluetooth Click board.

void bluetooth_enter_command_mode ( bluetooth_t *ctx );

• bluetooth_set_authentication The function set the authentication value to the RN-41 Bluetooth module on Bluetooth Click board.

void bluetooth_set_authentication ( bluetooth_t *ctx, uint8_t auth_value );

• bluetooth_set_security_pin_code The function set security pin code string to the RN-41 Bluetooth module on Bluetooth Click board.

err_t bluetooth_set_security_pin_code ( bluetooth_t *ctx, uint8_t *sp_code );

Application Init

Initializes driver and wake-up module.

void application_init ( void )
{
    log_cfg_t log_cfg;
    bluetooth_cfg_t cfg;

    /** 
     * 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.

    BLUETOOTH_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    bluetooth_init( &bluetooth, &cfg );

    Delay_ms ( 500 );
   
    log_printf( &logger, "Configuring the module...\n" );

    }

    }
    while( bluetooth_process( "AOK" ) != 1 );

    do
    {
        log_printf( &logger, " --- Operating mode --- \r\n" );
        bluetooth_set_operating_mode( &bluetooth, 0 );
    }
    while( bluetooth_process( "AOK" ) != 1 );

    do
    {
        log_printf( &logger, " --- Authentication --- \r\n" );
        bluetooth_set_authentication( &bluetooth, 1 );
    }
    while( bluetooth_process( "AOK" ) != 1 );

    do
    {
        log_printf( &logger, " --- Pin code --- \r\n" );
        bluetooth_set_security_pin_code( &bluetooth, &PIN_CODE_DATA[ 0 ] );
    }
    while( bluetooth_process( "AOK" ) != 1 );

    do
    {
        log_printf( &logger, " --- Exit command mode --- \r\n" );
        bluetooth_exit_command_mode( &bluetooth );
    }
    while( bluetooth_process( "END" ) != 1 );
    
    log_printf( &logger, "The module has been configured.\n" );
}

Application Task

Reads the received data.

void application_task ( void )
{
    bluetooth_process( "AOK" );
}

Note

Before starting to use this Click, it must be paired with other device.

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.
