Zigbee topology monitoting

[Bhavit Rajput]

I am working on zigbee network where I wanted to get the tree of whole network but could not find any utility from nordic which can provide those info, so I have started developing my own code, till now I can fetch all connected nodes successfully but I want the tree of network.

My query is can I use depth parameter from mgmt_lqi command to get network tree information?

If I can use depth then how can I use that depth value please explain.

Is there any other parameter should I look to get this tree?

Hi,

We don't have any tool such as the Thread topology monitor for Zigbee.

Since you are creating your own code I suppose you have already taken a look at the principle of operation for Thread topology monitor and try to recreate something similar for Zigbee reading the routers neighbor table.

You can get a router neighbor table in Zigbee using a ZDO Mgmt_Lqi_Req command, in the Zigbee CLI example you can use command 'zdo mgmt_lqi'. The format of the neighbourTableList of the mgmt_lqi_resp packet is documented here: https://infocenter.nordicsemi.com/topic/sdk_tz_v4.1.0/structzb__zdo__neighbor__table__record__s.html

The 'depth' field should give you the tree depth of the neighbor device.
