How to find out from the coordinator which Zigbee devices are connected to the network locally

[nickit94]

Hello,

I'm still trying to deal with the CLI-coordinator and I have a problem. I am using nRF52840 chip and SDK 4.0.0.

I just can’t understand how I can find out from the CLI-coordinator (through commands in the terminal, for example) which devices are connected to the network. And without broadcast requests. So far I'm using the zdo match_desc command:

zdo match_desc 0xffff 0xffff 0x0104 1 0x0000 0

but it is inconvenient and wrong. Why? For example, because some devices are currently unavailable, but they did not leave the network. Or, for example, with Xiaomi devices (which I managed to connect to the network) this does not work, because, as it seems to me, they do not use the Home Automation profile (0x0104).

Logically, when connecting new devices to the coordinator, he must write data about them to his memory.

My question is: what CLI command or using which function can I request a list of all connected devices to the network of this coordinator locally? And it would be nice to get some additional data about end devices (list of end points, list of clusters, etc.) as a bonus, if possible.

Thanks in advance.

Hi, 

The coordinator stores some data about each node, since each device has an unique TCLK, but I do not know if there is a way to retrieve this information, as it's part of the Trust Center transaction and the security layer.

There is a CLI command "zdo mgmt_lqi" which can be use to read the neighbouring table from a device. You can use this command to retrieve information about the network topology.

You will need to use active ep request and node descriptor request to discover properties on a node such  as endpoints, profile ID and clusters.

Best regards,

Hello,

Good thank you. I will try to do so.
