Unable to provision ESP32-S3/C6 with Google Home on iOS (CON-1353)

[AntoineSX]

Describe the bug
When trying to add either an ESP32-C6 or ESP32-S3 as a Matter device in Google Home, I receive an error stating: "Unable to Add Accessory. Home couldn't connect to this accessory." The device successfully connects when provisioned with HomeKit on iOS, but not with Google Home on iOS. However, it works correctly when provisioned on Google Home using an Android device.

@sayondeep Hello, Im looking for this problem too. I try connect matter device by google home on IOS, and got same error. I tried that with a Tapo matter socket, running on a Realtek chip. It runs normally with the same test.

Can we solve this please @sayondeep, @dhrishi, @chshu? I am experiencing this as well, and it is affecting the reputation of our devices sold! Please expedite this issue!

We are also experiencing this issue and it is significantly impacting our development process. A prompt resolution would be greatly appreciated. Please let us know if there's any additional information or testing needed from our side to assist in addressing this.

@thalesfsp, I tried commissioning the ESP-Matter latest Thread and Wi-Fi light using ESP32-C6, and it was successfully commissioned and added to the iOS Google Home App.

Initially, when I attempted to commission the Thread light using the ESP32-C6, I encountered the same issue you mentioned. However, after retrying, it worked successfully.

Here are the details of my setup:

Google Home App Version: 3.26.103
Google Nest Hub (2nd Generation):
Fuchsia Version: 22.20240805.103.161
Software Version: 62.0.7.676990136

So, it's. a matter of "keep retrying til it works". If this is a "solution", then close the issue. What else? Leave this ticket open for 9 years?

@thalesfsp Is this comment meant to be helpful, or are you just venting? What @VaishaliAvhale clearly mentioned is that she couldn’t reproduce the issue and has shared her setup details.

If you actually want this issue resolved, it would be more productive to provide useful information—such as reproduction steps, setup details, or logs—rather than speculative remarks.
