Failed to commission with Google Nest Hub.

[AkihiroN]

I am implementing a Matter device using the STM32WB5MMG. When attempting to commission the device with a Google Nest Hub, it fails to join the Thread Network.

Upon reviewing the logs, it appears that the NOC (Node Operational Certificate) verification is successful, but when trying to connect to the Google Nest Hub using the Thread Network information, there seems to be no response from the Google Nest Hub.

Could you suggest any solutions for this issue?

Hello @AkihiroN,

Looking at your logs, as you mentioned, it seems that the end device does not receive any response from the thread leader ( Nest Hub) on the channel 18, so it moves to the next channel. Can you please describe the setup especially the distance between the Nest hub and the end device ? Is it possible to move the device as closer as possible to the border router for test, and share the Google home application output.

Could you also provide binaries version you are using ?

Thanks & best regards,

Ouadi

Thank you for your confirmation.
We can confirm the same phenomenon when the device is placed close to the Google Nest Hub.
Google Home App shows the following logs.
[Unable to connect to threaded network (NEST-PAN-577A)].
I have erased all Thread/BLE Stack binary on M0+ side, application binary and external memory on M4 side as a test, and the same phenomenon is confirmed.
Please check the above.
