How will coordinator know when any node (router or end device) leaves the network?

Hi All,
I am working on Zigbee modules in API mode and I am getting proper results like when the node joins the network it is intimated to the coordinator by generating APID “ZB_IO_NODE_IDENTIFIER_RESPONSE” but I am also wondering for APID when node leaves the network. Could you please help me out regarding this?
Thanks for your time.


hey hi…could you please help me how to connect zigbee devices via connectport x8…please help me…it’s urgent…thank you

Coordinator is never informed when a module leaves the network.

You can perform a Node discovery to figure out what radios are still on the network. (ATND)

However, this does cause a lot of network traffic for a few seconds. So it shouldn’t be done all the time. If you can handle once every 20 minute then this might work for you.

Any other suggestions?
