Matter: Search for device then Can't find device

Rgv27 — Tue, 20 Feb 2024 06:30:13 GMT

I created matter virtual device with on/off clusters and it's working well but when I try with the physical device getting

"Search for Devices"

Logcat:

sipriyadarshi — Thu, 22 Feb 2024 19:27:39 GMT

Hello @Rgv27 ,

The log you shared tells us that commissioning failed at operational discovery, i.e. we did not get a response for mDNS queries after the device joined WiFi. We might be needing additional details regarding the physical device build (SDK commit, SOC, example used , etc). Also, could you inspect wireshark captured during commissioning.Without these details it is difficult for us to do a proper investigation of your issue.

Rgv27 — Fri, 23 Feb 2024 06:59:10 GMT

Hello @sipriyadarshi , Can you please tell me about the hub, is that require for connectivity with the single matter physical device to my app ?

Re: Matter: Search for device then Can't find device

Rgv27 — Fri, 23 Feb 2024 07:19:59 GMT

@sipriyadarshi , and also the certification of app is require on google console for commissioning of devices ?

Thanks

Re: Matter: Search for device then Can't find device

Rgv27 — Fri, 23 Feb 2024 14:51:34 GMT

Hi @sipriyadarshi , I am using Matter SDK with the Matter sample app and ChipTool

Re: Matter: Search for device then Can't find device

sipriyadarshi — Fri, 23 Feb 2024 18:44:08 GMT

Hub is not required for commissioning except for thread devices which require some thread infrastructure. However, if you want to control the device from GHA you need a Google Hub.

Re: Matter: Search for device then Can't find device

sipriyadarshi — Fri, 23 Feb 2024 18:46:11 GMT

You don't need to go through any certification process for the sample app.

Re: Matter: Search for device then Can't find device

Rgv27 — Mon, 26 Feb 2024 07:32:49 GMT

Thanks for reply @sipriyadarshi but

I didn’t find any log except I had mentioned above

So, Can you please describe some more details that are required for commissioning that how can I get a physical device ready for commissioning ?

I have a Tapo light as a physical device.

Check that your device can work with this network type and try again

then, how can I check my device work with which network type?

sipriyadarshi — Thu, 29 Feb 2024 22:19:26 GMT

Hello @Rgv27 ,

Tapo only supports 2.4 GHz. Based on your screenshot "Can't connect to 5exceptions_Mobile_Team5G", looks like you have a split network. Try testing everything using a 2.4GHz network only.

Re: Matter: Search for device then Can't find device

Rgv27 — Fri, 01 Mar 2024 07:06:03 GMT

Hi @sipriyadarshi , can we connect via call or any other resources that can I find fast response?

I tested with 2.4GHz network but still not getting success

and also I shared some code snippet when I click on add device

click on add device button

NOTE -

I am using all the functions, classes and requests from the sample Matter app, I have not made any changes in my app.
