Cannot use sample app to install matter device running on ESP32

[matdev]

I've two Matter wifi devices running on ESP32 devkits (C3 and S3) and a Google Nest.

I can install and control both of them nicely using Google Home app.

But I cannot install them using the default sample app for matter, neither using the targetcommissioner variant.

Can you please let me know what to do ?
Where should I put a breakpoint to check whether the device is scanned by the app ?

Best would be to start from scratch and provide logs to figure out what is going on.

• Reset the device under test (so it goes back to a commissionable state)
• Reset the sample app
  • App Info > Storage & cache > Clear storage
• Clear the logs of the phone
  • adb logcat -c
• Start capturing the logs of the phone
  • adb logcat > logs.txt

On your phone, start the sample app and click on "+" to commission the device.

Once processing is complete (e.g. it fails commissioning), kill the "adb logcat" command above, and attach the logs file to this issue.

Actually after a proper reset I was able to commission the device and control it from the sample app !
It took about 1 minute to complete, is it normal ?

Also, is it possible to install a device that's already commissioned with Google Home app ?
or can we query Google Nest for already commissioned Matter devices and install them in sample app ?

Yes, it should eventually be faster than that, but for now this could be expected.

Also, is it possible to install a device that's already commissioned with Google Home app ?

Yes. For that you have to use the "multi-admin" feature.

Settings > Google > Devices & sharing > Matter devices
Tap on the device
Tap on "Linked Matter apps & services"
Tap on "Link apps & services"
Tap on the sample app (GHSAFM) to trigger multi-admin to the sample app

Looks like this is being blocked by #60, which is being investigated.

Thanks for these infos Pierre.
I got the multi-admin feature working with default sample app after sharing the device with the GHSAFM-TC app.
Unable to do the initial commissioning with GHA so far.

I believe this is related to #61 which has been fixed.
