Get Zigbee Long Address inside of ZB_ZDO_SIGNAL_DEVICE_ANNCE

Hi,
I'm using:
nRF52840 Preview DK
Zigbee v2 (nRF5_SDK_for_Thread_and_Zigbee_2)
Segger Embedded Studio for ARM 3.52
Developing on a MacBook (macOS Mojave v10.14.5)
1) Is there any way to get the long address of a node connecting to the Zigbee network? I can get the short address through ZB_ZDO_SIGNAL_DEVICE_ANNCE in zboss_signal_handler:
    case ZB_ZDO_SIGNAL_DEVICE_ANNCE:
        {
            zb_zdo_signal_device_annce_params_t * dev_annce_params = ZB_ZDO_SIGNAL_GET_PARAMS(&sig, zb_zdo_signal_device_annce_params_t);
            printf("ZB Signal Device Annce, short address: %hx\n", dev_annce_params->device_short_addr);
            
            zigbee_connected_code(dev_annce_params);
}
break;
2) If that's not possible then is there any way to convert the Zigbee short address to the long address?
Thanks,
John

  • Hi, 

    Please use the latest ZigBee SDK which is v3.1.

    With the latest one, you can get the long address using "zb_zdo_signal_device_update_params_s".

            case ZB_ZDO_SIGNAL_DEVICE_UPDATE:
                {
                    char ieee_addr_buf[17] = {0};
                    zb_zdo_signal_device_update_params_t * p_update_params;
                    p_update_params = ZB_ZDO_SIGNAL_GET_PARAMS(p_sg_p, zb_zdo_signal_device_update_params_t);
                    UNUSED_RETURN_VALUE(ieee_addr_to_str(ieee_addr_buf, sizeof(ieee_addr_buf), p_update_params->long_addr));
                    NRF_LOG_INFO("Device has updated its status in the network, short address: %04x, long address: %s, status: %d",
                                 p_update_params->short_addr, NRF_LOG_PUSH(ieee_addr_buf), p_update_params->status);
                }
                break;

    I'm not sure that you want to get the long address before joining or after joining, but you can get it through that.

    I hope that this is helpful for you.

  • Justin, that was very helpful. Thank you!

    I updated my code to the latest ZigBee SDK v3.1.

    So when a Router connects to my Coordinator, I should receive the ZB_ZDO_SIGNAL_DEVICE_UPDATE signal and then I can keep a table of which Routers are connected. That takes care of one problem.

    Now, how does the Router get the long address of the Coordinator?

    Thanks,

    John
