[Matter] Connecting Google home app

[taoyinzhou]

Hi all，

I am developing the door lock using matter. The SDK uses ncs2.1.0, nrf/samples/matter/lock, and I want to test the connection to google home app on Android phone.

Information of test equipment:

52840dk (End Device)

google nest hub (Border Router)

pixel 4xl + Google Home App (Matter controller)

I first tried the example of door lock, but it failed to bind successfully in the app. Then I tried nrf/samples/matter/light_bulb, and the test result showed that it could be bound by app, and it could also control the light on/off through app.

So why are the results different between the light_bulb sample and the lock sample? Has anyone else tried it?

Attach the failed print log.

Hi Taoyin - Appreciate you sharing your experience here. I am curious whether you are using the "vanilla" NRF Connect as installed by Nordic's NRF Connect for Desktop, or whether you had to also install the patch that Google suggests on this page: https://developers.home.google.com/matter/vendors/nordic-semiconductor

"Download and apply the google-matter-preview patch, which contains fixes specific to the interop_testing_te9"

Asking because I am still struggling to get basic matter commissioning working through the Google Home App (although I am able to get it to work fine using the Android Chiptool App with an EERO6 as an OTBR). As an aside, I am using the NRF5340DK.

Thanks! Dan.

Hi, have you been able to commission and control a light example or door lock example with Google Home App? I have a similar problem to yours, but since Google start supporting Matter 1.0 I'm able at least to do successful commissioning but after it's done my Matter device is displayed as Offline. 
I'm using nRF5340  with Light example from SDK 2.1.2, Nest Hub 2.  Google integration as below.
