Zigbee router join signal

[Marco]

A happy new year everyone,

I should develop a mesh sensor network for Raytheon Anschütz GmbH in Germany but I am an absolute beginner on Zigbee and therefore struggle a lot with basic functionalities. 

I tried the Zigbee light switch example and would like to monitor the joining process on the coordinator as I have to maintain a list of all connected network devices.

I added the following case to the  zboss_signal_handler() in the coordinator code:

        case ZB_ZDO_SIGNAL_DEVICE_ANNCE:
            {
            zb_buf_t                    * p_buf = ZB_BUF_FROM_REF(param);
            zb_apsde_data_indication_t * p_ind  = ZB_GET_BUF_PARAM(p_buf, zb_apsde_data_indication_t);
           NRF_LOG_INFO("Joined Addr = 0x%02x\r\n", p_ind->src_addr);
            }
            break;

When the light_switch_enddevice joins the network, the signal is catchen and it prints the short addr.
When the router (light_bulb) joins the network nothing happens, even when the router report a successful connection and the LED is turned on.

When I start the cli example and start the device as router the signal is caught. 

Can you explain what is the difference between the cli router and the light_bulb router and what I have to change to receive the device_annce signal. 


My application requires all devices to be routers. How can I get the short addr for all routers joining the network?


I hope you can help me. Please feel free to contact me as well via phone under [phone]

Best regards

I think another user has solved the same problem: https://devzone.nordicsemi.com/f/nordic-q-a/39739/zigbee---observing-the-joining-proecedure-of-a-device.

Hi, thank you for your reply, but did you actually read my text? 

I added exactly what was suggested in this reply and the join signal is not catched for the router. The enddevice is working though. 

Best regards Marco

Aah, I'm so sorry I missed that!

There is no difference between cli router and a light bulb. We've tested it and I see a device announce signal on the coordinator. This signal is a result of receiving Device_annce command which is send using broadcast. Perhaps coordinator missed it.

We'll talk to DSR (ZBOSS stack vendor) if they see a way to get a list of all connected devices. This is not the first time we've see this question.
