Problems when integrating Matter protocol

[Pelle]

Hi,

I'm trying to integrate Matter protocol but encounter some problems. 
We're using nrf5340 devkit, and Zephyr.

1. There seems to be two repositories, what is the difference?:

https://github.com/project-chip/connectedhomeip

and

https://github.com/nrfconnect/sdk-connectedhomeip

2. When I tried integrating the first one (https://github.com/project-chip/connectedhomeip) the build system of my project complains about CONFIG_CHIP=y.
Then I saw the following guide: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/matter/BUILDING.html
But the compilation fails when running "ninja -C out/host", I cloned the master branch from https://github.com/project-chip/connectedhomeip

3. When I instead used https://github.com/nrfconnect/sdk-connectedhomeip and cloned latest release, our build system doesn't complain about CONFIG_CHIP=y, but get some other errors.

Hi, 

We only support nRF Connect SDK in our integration layer and we can't really help if the customer wants to use the vanilla Zephyr. That is, all the development was with nRF Connect SDK in mind, and we cannot guarantee it will work without code changes in a different context.

Another dev has started the process of adding support for the pure Zephyr platform (https://github.com/project-chip/connectedhomeip/pull/19504/files), but no examples have been provided as part of this effort, so you would need to figure out on your own how to use it.

What's possibly the problem when adding CONFIG_CHIP to connectedhomeip is that that repository supports multiple Zephyr-based platforms so an application must explicitly select the right zephyr module: https://github.com/project-chip/connectedhomeip/blob/master/examples/lock-app/nrfconnect/CMakeLists.txt#L32. That's why I strongly recommend analyzing the existing examples to understand all required configuration pieces. .

Ok thank you, I will look into that last link you sent to figure out how to configure, that was good information!

Hello, did you figure out the way to integrate CHIP (matter) into your Zephyr project?
