ZigBee Click

ZigBee 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 : Oct 2021.
• Type : UART type

Software Support

Example Description

This is an example that demonstrates the use of the ZigBee Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.ZigBee

Example Key Functions

• zigbee_cfg_setup Config Object Initialization function.

void zigbee_cfg_setup ( zigbee_cfg_t *cfg );

• zigbee_init Initialization function.

err_t zigbee_init ( zigbee_t *ctx, zigbee_cfg_t *cfg );

• zigbee_default_cfg Click Default Configuration function.

err_t zigbee_default_cfg ( zigbee_t *ctx );

• zigbee_send_at Function merges two string and sends it to device.

void zigbee_send_at ( zigbee_t *ctx, uint8_t *at_buf, uint8_t *suffix_buf );

• zigbee_resp Function checking driver buffer string.

uint8_t zigbee_resp ( zigbee_t *ctx, char *data_in );

• zigbee_set_pin_rst Function setting RST pin status.

void zigbee_set_pin_rst ( zigbee_t *ctx, uint8_t status );

Application Init

Initialization of driver, UART ISR and then configures device. Depending on previous selected device mode it creates new PAN network or joins to one.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    zigbee_cfg_t zigbee_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

Host mode: Broadcasts message 'MikroE' every 3 seconds. User mode: Cheks if something is received.

void application_task ( void )

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.
