This automated output is generated by the PR linter DangerJS, which checks if your Pull Request meets the project's requirements and helps you fix potential issues.

DangerJS is triggered with each push event to a Pull Request and modify the contents of this comment.

Please consider the following:
- Danger mainly focuses on the PR structure and formatting and can't understand the meaning behind your code or changes.
- Danger is not a substitute for human code reviews; it's still important to request a code review from your colleagues.
- To manually retry these Danger checks, please navigate to the Actions tab and re-run last Danger workflow.

Review and merge process you can expect ...

We do welcome contributions in the form of bug reports, feature requests and pull requests.

1. An internal issue has been created for the PR, we assign it to the relevant engineer.
2. They review the PR and either approve it or ask you for changes or clarifications.
3. Once the GitHub PR is approved we do the final review, collect approvals from core owners and make sure all the automated tests are passing.
- At this point we may do some adjustments to the proposed change, or extend it by adding tests or documentation.
4. If the change is approved and passes the tests it is merged into the default branch.

@lucasssvaz - what is the reason for removing matter_light specific target default sdkconfig? Those are examples.

We already talked about it - question answered.

LGTM

[Jason2866]

@SuGlider Is it planned to adopt the example to work with actual Arduino Core 3.2.0?
Currently it is only for Arduino Core ~3.0.5

@Jason2866 - Could you please share your findings about this issue? Thanks!

I guess this is about https://github.com/espressif/arduino-esp32/blob/master/idf_component_examples/esp_matter_light/main/idf_component.yml

dependencies: espressif/esp_matter: version: "^1.3.0" # Adds Arduino Core from GitHub repository using main branch espressif/arduino-esp32: version: "^3.0.5" override_path: "../../../" pre_release: true # testing - using Arduino from the repository # version: "master" # branch or commit # git: https://github.com/espressif/arduino-esp32.git 

That shall be solved with the changes:

dependencies: espressif/esp_matter: version: ">=1.3.0" # Adds Arduino Core from GitHub repository using main branch espressif/arduino-esp32: version: ">=3.0.5" override_path: "../../../" pre_release: true

@SuGlider Try to compile. Compile errors come up when trying with Core 3.2.0 and IDF 5.4.1+

I have done it. I was able to build the Matter application for the ESP32 using Core 3.2.0, IDF5.4.1 and Matter 1.4.0.

I have checkout this PR, installed IDF v5.4 and imported the Arduino as Component Matter Light project from the repository.
I have modified the main/idf_component.yml file to comment out the last 2 lines (override_path: "../../../" and pre_release: true). I have run idf.py set-target esp32 and then idf.py build. All good.

[Jason2866]

@SuGlider Dont get it going with branch master and IDF 5.4.1+ from 25.04.11

This error is related std::to_underlying it needs C++ 23.
I have changed the CMakeLists.txt file in this PR to use C++ 2a.
d8e7a91

Try that change within pioarduino and let me know.

[SuGlider]

@Jason2866 - please evaluate pioarduino/platform-espressif32#146

[Jason2866]

@SuGlider Will do. Needs a pio python script to change the used c++ version.

[Jason2866]

Just noticed we need to fix the Arduino Lib Builder pioarduino script.
There is this entry

CXXFLAGS=[ "-march=rv32imc_zicsr_zifencei", "-std=gnu++2b", "-fexceptions", "-fno-rtti", "-fuse-cxa-atexit", "-std=gnu++2a" ], 

I guess it fetches the different settings from normal run and the Matter run. Similar issue than adding the ndebug entry.
I can't override correctly when two set here.

[Jason2866]

This weird setup does work:

build_unflags = -std=c++17 -std=gnu++2b build_flags = -std=gnu++2a 

[SuGlider]

This weird setup does work:

build_unflags = -std=c++17 -std=gnu++2b build_flags = -std=gnu++2a 

does this setup build it for pioarduino?
I have tried 2b but it fails with Matter 1.4
2a is the best ESP Matter can go.

[Jason2866]

Yes, this setup does build successfully. It uses Matter v1.4. and ++2a

Thx for your help!
