Problem of connection between Nordic's zigbee device and other Zigbee device

[Raffaela]

Hi,

I have a problem with a specific Zigbee certified device that I can't connect to my Nordic device.

When trying to connect to the device, I go to see the status:

void zboss_signal_handler(zb_uint8_t param)
{
    zb_zdo_app_signal_hdr_t  * p_sg_p = NULL;
    zb_zdo_app_signal_type_t   sig    = zb_get_app_signal(param, &p_sg_p);
    zb_ret_t                   status = ZB_GET_APP_SIGNAL_STATUS(param);
    zb_bool_t                  comm_status;

    switch (sig)
    {
        case ZB_BDB_SIGNAL_DEVICE_FIRST_START:
        case ZB_BDB_SIGNAL_DEVICE_REBOOT:
            
            if (status == RET_OK)
                        {
                NRF_LOG_INFO("Joined network successfully");
                bsp_board_led_on(ZIGBEE_NETWORK_STATE_LED);
            }

and it is equal to -1, so it is not RET_OK.

It's the first time that I have this problem of interoperability. Is it necessary to do something specific so that the Nordic device is visible from any other Zigbee device?

Best regards,

Raffaela

Hi Raffaela,

Which nordic example are you using and what do you which device do you want to connect to? Are you sure both devices are running on the same zigbee channel?  By default, our examples operates on channel 16 only. In case someone tries to connect .e.g. our light switch example to his network and his network is set on channel 15, the device will not join.

Hi Marjeris,

Thank you for your reply. I'm using the light bulb example. I'm sure that the channel is correct because I'm using the sniffer and I see the zigbee traffic. The device is one of the Zigbee Alliance that it has the Zigbee Certification (Zigbee 3.0).

Thank you, 

Raffaela

Is the device a coordinator? Do you have a Zigbee network open where both devices can join?

[Raffaela]

Yes, the device is a Coordinator. Yes, the Zigbee network is opened.

Thank you,

Raffaela

Can you post the sniffer logs when you try to join the network?

[Raffaela]

Now I see a very strange behaviour: by the sniffer log, you can see that the connection is happened but, in the zboss_signal_handler, I see the status = -1 so the connection is not happened. How is this possible?

I tried to use also this function "zb_bdb_set_legacy_device_support(0);" but it doen't help. The ERASE_PERSISTENT_CONFIG is set to ZB_FALSE.

Thank you, 

Raffaela

Hi Raffaella,

The signal change once the TCLK exchange is completed, but this is not despicted in the screenshot. Could you please send me the whole traffic dump and not just a screenshot? Please use .pcapng file format if possible.

Best regards,

Marjeris
