Zigbee Router Device - Frequent Extended Address Request

[javierbio]

Dear community, good afternoon

We have been working with a coordinator, a router device and an end device all based on nRF52840 (Fanstel BT840F module) with nRF5_SDK_for_Thread_and_Zigbee_v4.0.0_dc7186b

Using Wireshark I see that every 300 seconds (aprox.) the router device sends an Extended Address Request to the coordinator. The coordinator replies the request succesfully.

Enclosed you will find Wireshark capture. Router Device Address = 0x6ADF. Use zbee_zdp filter

Is this a normal behaviour for Zigbee 3.0 router devices?. The end device don´t present this behaviour.

Thanks for your comments.

Best regards,

Hi,

I don't see any reason why the router should send Extended Address Request periodically, and I can't say that it's normal behaviour as far as I know. I just checked several sniffer logs I had from before, as well as tested with the light control example now, and I didn't see this behaviour in any of the sniffer logs.

Is your program based on one of the examples in the SDK? If so, which one, and have you made any significant changes to it?

Best regards,

Marte
