Hi.

The data path in ZigBee is dynamic, the path between routers is found by Route Request/Response packets, but for ZED the path always goes through a parent node that is selected upon bootup and each disconnection. As a result - ZED does not know the full path, only the single-hop destination. The same applies for routers along the data path. For routers there is one exception though - if the destination node uses source routing. In such situation you may see the whole data path at the collector node.

I will recommend that if you want to see the path packets take throught the network you should use a packet sniffer and Wireshark. If you only care about a particular end device it should be sufficient to check its parent node.

Best regards,

Andreas

I want to know that

if i install router between coordinator and end devices, router plays well the intemediate node role.

but currently i cannot know whether end devices transmit packets directly to coordinator or via router.

In summary, i want to know the router play well or not.

Hi.

What problem are you trying to solve, can you please elaborate more the problem on a high level?

Do you only have 2 or 3 devices in your network, or will you add more devices?

Best regards,

Andreas
