NINA-B222 Click

NINA-B222 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.

• Type : UART type

Software Support

Example Description

This example desmonstrates the use of NINA-B222 Click board by processing the incoming data and displaying them on the USB UART.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.NINAB222

Example Key Functions

• ninab222_cfg_setup Config Object Initialization function.

void ninab222_cfg_setup ( ninab222_cfg_t *cfg );

• ninab222_init Initialization function.

err_t ninab222_init ( ninab222_t *ctx, ninab222_cfg_t *cfg );

• ninab222_set_device_name This function sets the local name used as device name for Bluetooth Classic.

err_t ninab222_set_device_name ( ninab222_t *ctx, uint8_t *device_name );

• ninab222_set_connectability This function sets the GAP connectability mode by using the UART serial interface.

err_t ninab222_set_connectability ( ninab222_t *ctx, uint8_t c_mode );

• ninab222_set_enter_mode This function requests the module to move to the new mode by using the UART serial interface.

err_t ninab222_set_enter_mode ( ninab222_t *ctx, uint8_t enter_mode );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    ninab222_cfg_t ninab222_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_info( &logger, " Application Task " );
    Delay_ms ( 100 );
}

Application Task

Reads and processes all incoming data and displays them on the USB UART.

void application_task ( void ) 
{
    if ( NINAB222_OK == ninab222_process( &ninab222 ) ) 
    {
        ninab222_log_app_buf( );
        ninab222_clear_app_buf( );
    }
}

Note

• Recommended Android application at the link: https://play.google.com/store/apps/details?id=de.kai_morich.serial_bluetooth_terminal
• Before using this Click, it must be paired with your devices.

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.
