XBEE 2 Click

Xbee 2 Click is a compact add-on board providing wireless end-point connectivity to other devices. This board features the XB3-24Z8UM, a Digi XBee® 3 transceiver module offering a fully interoperable ecosystem covering all vertical markets from Digi International. Building on industry-leading technology, the pre-certified Digi XBee® 3 module delivers the flexibility to switch between multiple frequencies and wireless protocols as needed (Zigbee, 802.15.4, DigiMesh® and BLE). It can be easily configured and controlled from a simple, central platform and comes with built-in Digi TrustFence® security, identity, and data privacy features which use more than 175 controls to protect against new and evolving cyber threats.

Click library

  • Author : Stefan Filipovic
  • Date : Aug 2022.
  • Type : UART type

Software Support

We provide a library for the XBEE 2 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 XBEE 2 Click driver.

Standard 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 );

Example key functions :

  • 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 );

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.

The demo application is composed of two sections :

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
}

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.XBEE2

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.
