Unable to add ESP32-C6 to an existing Thread network (CON-1189)

[amroncz]

Hello,

I have an ESP32-C6 and flashed it with the “light” example.

I used the exact example and didn't change anything. I was able to integrate my device with the example QR code (https://docs.espressif.com/projects/esp-matter/en/latest/esp32c6/developing.html#commissioning-and-control) into both Home Assistant and Alexa.

After I adjusted the values for the device for Thread as described here (https://docs.espressif.com/projects/esp-matter/en/latest/esp32c6/developing.html#flashing-the-firmware)

ESP32-C6 supports both the Wi-Fi and IEEE 802.15.4 radio, so you can run Wi-Fi or Thread matter example on it.

To enable Thread, you should change the menuconfig options to CONFIG_OPENTHREAD_ENABLED=y, CONFIG_ENABLE_WIFI_STATION=n, and CONFIG_USE_MINIMAL_MDNS=n.

and flashed it again, I can neither integrate it into Home Assistant nor directly into Alexa via my Echo, which acts as a Thread border router.

@amroncz If you want to quickly try the light example with ESP32-C6 Thread enabled, you can choose ESP32C6 in the thread_light option in ESP Matter Launchpad

Unfortunately, that won't help me any further. I'm trying to learn how to use ESP devices and Matter using the example. So I'm trying to understand step by step what I need to do.

Can you share your sdkconfig in the above case where you want to commission esp32c6 over thread. From the logs, it seems that the options you had set are not enabled in the sdkconfig.

Here is my sdkconfig file. I use the Visual Studio esp-idf extension for the configuration.

sdkconfig.txt

@amroncz , I have tried to reproduce the issue with esp32c6 and thread options enabled and my device got successfully commissioned over thread. You seem to be using idf v5.2.2. I have tested the things with the idf v5.2.2 setup as well. The device gets commissioned successfully over thread without any wifi logs.
You can try the steps below and get back:
i) Please do a clean build using rm -rf build sdkconfig sdkconfig.old managed_components dependencies.lock.
ii) set the target as esp32c6 using idf.py set-target esp32c6.
iii) Enable the thread related options you mentioned above.
iv) Flash the app using idf.py erase-flash flash monitor and commission the device using alexa or apple.

That worked for me. I was able to control the device via Matter over Thread with both Alexa and Home Assistant.
Alexa indicated that it was not a valid Matter device, but I had that with Matter over Wifi too and the configuration still worked.

Probably the clean build or erase-flash did it...

Many thanks for your help @shripad621git
