Can not received Sigma1 msg from Alexa Dot (CON-613) #503

Closed sidhoo2 closed 1 year ago

Hi,

Alexa APP info name：Echo Dot-4V1 version：0009094444164 Alexa ver：App version 2023.13 build version 2.2.517011.0

Alexa fails to add Matter devices, but our matter products can be added by Apple Home/Google Home, and there will be no prompt that the device is not certified. the device logs indicate that no Sigma1 msg from Alexa has been received.

@sidhoo2 Can you please check if you can see the device advertising over mDNS once it connects to the AP. You can use the below command from a host machine present on the same Wi-Fi network as that of the device -

avahi-browse _matter._tcp -r

If you see your device in the response (which you should, ideally) then your observation would be correct -

no Sigma1 msg from Alexa has been received.

Also, this seems to be a different example. Can you please try with esp-matter light example just to confirm the working?

Do you use BLE while the commissioning is going on?

@dhrishi Thank you for ur response

If you see your device in the response (which you should, ideally) then your observation would be correct - Yes, i can see the response from the device. So we reset the Router and turn on IPv6, it works ! Why it can be connected with Google Home ?

@sidhoo2

So we reset the Router and turn on IPv6, it works !

So, you mean, when you enable IPv6 on the router then the commissioning with Alexa works fine?

dhrishi commented 1 year ago

Closing this now as the commissioning was successful
