Zigbee coordinator with Xiaomi devices

[Amigo]

Hi all!

I found solution for Xiaomi zigbee smart home sensors (gerkon, water sensor, pir motion, and other...) based on CC2530 zigbee shepherd and Trust Center Link Key from lthis ink.

Heve anybody an idea how to implement nrf52840 zigbee light coordinator code to cominicate with Xiaomi devices?

I tried to use it, but i dont inderstand where i have to paste key in source code, when i try to join to network code return  info with unknown signal parameter....

Look for ZIGBEE_CHANNEL in sdk_config.h

Hi Edvin,

Right. I was wondering if there were a specific Channel to choose in order to communicate with Xiaomi devices or whether any channel would work.

You need to use the same channel as your devices. I am not sure what channel your devices uses, but check out this thread:

I don't have any Xiaomi devices, so I can't test. Alternatively, you can just try all the channels (11 to 26).

Best regards,

Edvin

Hi Clem,

In a most common case, a device after a factory reset scans through all possible channels and attempts to join an opened network, that has the best signal strength. 

If you have no idea whether the network is opened, restart the coordinator node. In Nordic's examples the coordinator opens a network upon boot-up.

For third party coordinators/hubs usually one of the default ZLL channels is preferred.

Going back to your question: there is none, just make sure to factory reset the Xiaomi device.
