XBEE 2 Click

XBEE 2 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 demonstrates the use of an XBEE 2 Click board by showing the communication between the two Click boards configured in transparent mode.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.XBEE2

Example Key Functions

• xbee2_cfg_setup Config Object Initialization function.

void xbee2_cfg_setup ( xbee2_cfg_t *cfg );

• xbee2_init Initialization function.

err_t xbee2_init ( xbee2_t *ctx, xbee2_cfg_t *cfg );

• xbee2_get_serial_number This function sends a get serial number command.

err_t xbee2_get_serial_number ( xbee2_t *ctx );

• xbee2_set_device_name This function sets the device name (node identifier).

err_t xbee2_set_device_name ( xbee2_t *ctx, char *dev_name );

• xbee2_set_destination_address This function sets the destination address high and low bytes.

err_t xbee2_set_destination_address ( xbee2_t *ctx, char *dest_addr_high, char *dest_addr_low );

Application Init

Initializes the driver and configures the Click board by performing a factory reset, and setting the device name, destination address, api mode to transparent, and a device role to join or form network depending on the application mode.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    xbee2_cfg_t xbee2_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

Depending on the selected application mode, it reads all the received data or sends the desired message every 3 seconds.

void application_task ( void )
{
#ifdef DEMO_APP_TRANSMITTER
    xbee2_generic_write( &xbee2, DEMO_TEXT_MESSAGE, strlen( DEMO_TEXT_MESSAGE ) );
    log_printf( &logger, "%s", ( char * ) DEMO_TEXT_MESSAGE );

    Delay_ms ( 1000 );
    Delay_ms ( 1000 ); 
#else
    xbee2_process( );
    if ( app_buf_len > 0 ) 
    {
        log_printf( &logger, "%s", app_buf );
        xbee2_clear_app_buf(  );
    }
#endif
}

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.
