How to Retrieve Device Link Quality Details Using a Short Address in a Zigbee Network with nRF Connect SDK

[Dalvadi Anil]

I am working on a Zigbee network using the nRF Connect SDK and need to retrieve the link quality information (LQI) of a specific device based on its short address. What ZDO commands or APIs should I use to fetch this information, and how can I process the response to get the link quality details?

Hi, 

You can use the zb_zdo_get_diag_data() function. See nRF Connect SDK ZBOSS API for more details.

Hi Amanda,

Thank you for your suggestion; the zb_zdo_get_diag_data() function worked perfectly for me!

I have one more question: how can I determine if a device is disconnected, such as when it powers off? Is there a specific way to detect this in the nRF Connect SDK ZBOSS API?

Regards,

Anil

Hi Amanda Hsieh 
WIll zb_zdo_get_diag_data provide correct value if its connected via other router as well?
or it will provide for rssi with coordinator only if its in range with coordinator and 0 if its connected via router?
