Matter Lock example

[Dan]

Hi - I am using the  /nrf/samples/matter/lock sample as a reference template to develop my own app. Thank you for providing it!

I am able to build and flash the basic build (without DFU enabled) and it seems to work fine on the NRF5340 DK board.

1. Despite building, flashing and seemingly working fine, there are 39 “Problems” reported in VS Code. 38 are warnings, and 1 error: “CMake Error at /opt/nordic/ncs/v1.8.0/zephyr/cmake/extensions.cmake:2413 (message):BOARD is not being defined on the CMake command-line in the environment or by the app.” I am not sure how to get rid of this error - I did specify my board in the VS build configuration dialog correctly as nrf5340dk_nrf5340_cpuapp. I would also welcome feedback/guidance on the 38 warnings to better understand how to fix them. I enclose below the errors and warnings.
2. I would like to be able to use a mainstream, commercially available thread border router to connect my NRF5340 DK to the internet. I have the latest Apple Homepod mini, however it appears (e.g. https://devzone.nordicsemi.com/f/nordic-q-a/79587/do-matter-samples-from-nrf-connect-sdk-support-homekit) that Apple is not yet supporting the commissioning of Matter accessories. Do you know of any other mainstream (i.e. Google, Amazon, Apple), commercially available thread border routers that would currently work for this? How can we best develop and test an end-user flow for a consumer using our Matter accessory?
3. Currently, Nordic recommends using the Android CHIPTool app to commission and control a Matter accessory. Is there any plan for providing a reference example/app for iOS, and if so, what is the expected timing of such?
4.  When I try to build a multi-image DFU version, using prj_multi_image_dfu.conf as the project configuration file and specifying -DBUILD_WITH_DFU=MATTER as a CMake argument in the VS Code build configuration dialog’s “Extra CMake arguments” as specified in the instructions, the build fails with the following error: “ ValueError: ('invalid bool MATTER', 'on line 35: BUILD_WITH_DFU:BOOL=MATTER\n'). Instead, if I try using -DBUILD_WITH_DFU=1 it seems to build fine. The CMakeLists.txt checks “if(BUILD_WITH_DFU)”... is there an error with the documentation/instructions, or am I doing something wrong here?

Thanks! Dan.

Hi Dan,

After some exploration, I got the following suggestions for you:

1) Try to clean up your extensions first. Uninstall the extensions related to C/C++ first, reinstall the nRF Connect Extension Pack, restart VS Code.

2) After above step, you should see only one error and several warnings appear. The error has a solution mentioned here Kconfig.defconfig:11: error: couldn't parse 'default $(dt_node_int_prop_int,/cpus/cpu@0,clock-frequency)' · Issue #41093 · zephyrproject-rtos/zephyr · GitHub

Best regards,

Charlie

Hi Charlie - Thanks for digging into this further and for your suggestions which I followed (I removed all extensions, reinstalled nRF Connection Extension Pack from within VS Code, and restarted VS Code).

When it first opens up, it does indeed only show one warning. However, as soon as I click into app_task.cpp it presents 14 errors and 1 warning (it can still build and flash and work properly despite these, which leads me to believe it is a VS Code/Intellisense configuration issue and not an actual issue). However I would like to get it resolved so that when I have real issues, VS Code can alert me of them properly.

When VS Code first opens:

After clicking in to app_task.cpp:

Would you be able to share your lock/.vscode/c_cpp_properties.json file contents so I can compare to mine? Also, if you have the output from VS Code for Generate Support from an M1 Mac I would welcome having a look at it to compare it to mine.

Thanks! Dan.

Hi Dan,

I am not sure how you create this file. I do not have c_cpp_properties.json in my current project folder or working space, the default C/C++ extensions setting should work. It is also worth mentioning the solutions mentioned on another ticket if you want to learn more.

Problems with VS Code - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)

You may realize all the PROBLEMS reports are issued by assistant extensions and may be caused by improper configuration. Some of the extensions are not originally designed or optimized for Zephyr/NCS project and they are not intelligent enough for the complex structure of Zephyr/NCS like the following issue report. We have no quick solution for these kinds of problems since these extensions are maintained by other people or origination under open-source licenses. They have no influence on the building process. As long as the building process does not report errors, you can focus on your development safely. 

nRF9160DK ver 0.9.0 - application software show error during build. asset_tracker_v2 in v1.7.1 - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)

Hi Charlie  - Totally understand re: 3rd party extensions and Nordic reasonably not being in a position to police them. I should note that I am only now using the NRF Extension pack extensions and not changing the default configuration and still get a lot of warnings and errors.

That being said, I did try a couple of things that greatly reduced the number of warnings/errors reported by VS Code and I am sharing here in case it can benefit anyone else:

1) Add to your c_cpp_properties.json in VS Code the following configurations (source/credit):

"compileCommands": "${workspaceFolder}/build/compile_commands.json",

"configurationProvider": "ms-vscode.cmake-tools"

2) run (source/credit): 

west config build.cmake-args -- -DCMAKE_EXPORT_COMPILE_COMMANDS=ON

For now, I am going to try and ignore the issues with the dev environment and focus on development and building my application. It is still a little mysterious why we should have such different VS Code experiences if we are both starting from a clean install and I would be happy to make myself available to the Nordic team to debug it if anyone wants to do a real-time, interactive session. Thanks! Dan.
