Hi,

I'm sorry for the late reply.

The short address (Nwk Addr) of the ZC will be 0x0000. You can test this out yourself with the CLI agent sample if you want to. After setting the devices role as ZC with "bdb role zc" and starting the network with "bdb start", you can check the devices short address with "zdo short". You can get IEEE address using the short address with zb_address_ieee_by_short.

Best regards,

Marte

At ZC (Zigby Light Coordinator sdk),
The long address of ZC can be found by using zb_get_long_address.

However, the function zb_get_short_address , which returns short-address, is missing and an error appears.

However, I want to get the short or long address of ZC from ZED.

Is there a way?

thanks

Short address defined to 0xffff means the broadcast message.Anyone can access the message.If you want to send the unique ZC, you have to fill the address of long or short address of coordinator.

By the way, zigbee can assign the PANID and channel to define the group.

The ZC was set up as follows:

/* receive test */

static zb_void_t zcl_receive(zb_bufid_t  *bufid)
{
    NRF_LOG_INFO("zcl test");
}
/* receive test */




int main(void)
{
    zb_ret_t       zb_err_code;
    zb_ieee_addr_t ieee_addr;
    
    timers_init();
    log_init();
    leds_buttons_init();
    
    ZB_SET_TRACE_LEVEL(ZIGBEE_TRACE_LEVEL);
    ZB_SET_TRACE_MASK(ZIGBEE_TRACE_MASK);
    ZB_SET_TRAF_DUMP_OFF();

    /* Initialize Zigbee stack. */
    ZB_INIT("zc");

    /* Set device address to the value read from FICR registers. */
    zb_osif_get_ieee_eui64(ieee_addr);
    zb_set_long_address(ieee_addr);

    /* Set channels on which the coordinator will try to create a new network. */
    zb_set_network_coordinator_role(IEEE_CHANNEL_MASK);
    zb_set_max_children(MAX_CHILDREN);
    
     /* zigbee receive test */
    ZB_ZCL_REGISTER_DEVICE_CB(zcl_receive);
    
    zigbee_erase_persistent_storage(ERASE_PERSISTENT_CONFIG);
    
    zb_err_code = zboss_start_no_autostart();
    ZB_ERROR_CHECK(zb_err_code);
    
    while(1)
    {
        zboss_main_loop_iteration();
        UNUSED_RETURN_VALUE(NRF_LOG_PROCESS());
    }
}
