RN4678 Click

RN4678 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.

void rn4678_exit_command_mode ( rn4678_t *ctx );

• rn4678_set_device_name Set the device name function.

void rn4678_set_device_name ( rn4678_t *ctx, uint8_t *name );

Application Init

Initializes the driver and configures the Click board.

void application_init ( void )
{
    log_cfg_t log_cfg;
    rn4678_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_printf( &logger, "The module has been configured.\n" );
    
    rn4678_set_cts_pin( &rn4678, 0 );
}

Application Task

Checks for the received data, reads it and replies with a certain message.

void application_task ( void )
{
    rn4678_process( PROCESS_LOG_RSP );
}

Note

We have used the Serial Bluetooth Terminal smartphone application for the test. A smartphone and the Click board must be paired in order to exchange messages with each other.

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.
