ESP32 Forum

Hello,
I would like to build ESP32 matter application to my ESP32 device.
From what I've seen, Matter is not supported yet as part of the ESP-IDF and requires a separate project under the CHIP github.
First I made sure I have a working connectedhomeip environment by building it using the connectedhomeip tools.Then I followed the instructions to build the matter application for ESP32 here: https://github.com/project-chip/connect ... /README.md
Successfully executed all the steps until I try to run idf.py set-target esp32 (from connectedhomeip/examples/all-clusters-app/esp32)
I get an error message: Failed to resolve component 'openthread' see full log below.

I am not sure why openthread is even required, given that the ESP32 does not have the radio to support it. Could it be environment configuration issue?

Appreciate any help,
Thanks in advance

I know Matter is relatively new, so maybe not a lot of knowledge in the forum... Appreciate anyone that can propose a direction here!

Thanks!

You can try to update the esp-idf version to v4.4.1, then build it again.

Hi,

I am facing the same issue when trying to build the all-clusters-app matter project for esp32.
Development kit that I have is ESP32-DevkitC_V4.

Have followed all the steps from the links:
https://blog.espressif.com/announcing-m ... 164316c0e3
https://github.com/project-chip/connect ... /README.md

Able to successfully complete the steps mentioned below
$ source ./scripts/bootstrap.sh
$ source ./scripts/activate.sh

Once I complete the above steps next step is to set the target to esp32.
$ idf.py set-target esp32

However, When I run the command following command to set the target to esp32:
idf.py set-target esp32 , I get the error: Failed to resolve component ‘openthread’
Please see attachment snapshot of the error - Failed_to_resolve_component_openthread.png.


Please let me know how to resolve the above error .

Also everytime I run the command , I have to manually delete the build folder , it doesnot automatically clean the folder.
Please see error - build_dir_need_to_delete_manually.png
Once i delete the build folder manually, the build starts but it gives error - Failed to resolve component ‘openthread.

Please let me know how to resolve the error Failed to resolve component ‘openthread', so that I can set the target and build the code.
Would really appreciate your quick help on this.


Best Regards,
Swapna.
