Matter SDK integration

[Sanjaykishor]

Hi,

We are currently trying to integrate the matter SDK with our application and we came across the chip tool (POSIX CLI) provided by Project Chip.

POSIX CLI - Currently using this tool for commissioning the device and sending commands to the end device for evaluation purposes.

So my questions are

1. How the chip tool handles the unsolicited response from the end device?

2. How the chip tool communicates with the matter application layer?

3. Which implementation, Python or POSIX CLI, would be more appropriate for our Linux-based project with a limited memory and storage capacity of 512 MB?

Hi,

Note that these tools are common for the Matter implementation, and not Nordic specific. Nordic is not developing these tools, and have limited knowledge/support for internal workings.

1. You need to use interactive mode: https://github.com/project-chip/connectedhomeip/blob/master/docs/guides/chip_tool_guide.md#interactive-mode-versus-single-command-mode

2. This question is about specific implementation details of CHIP Tool, which is not implemented by Nordic. Please post this as a GitHub issue in project-chip/connectedhomeip space.

3. We recommend to use POSIX Chip-tool rather than Python-based version - as this is our reference controller implementation used in testing and delivered as part of nRF Connect SDK release artifact. It is up to you as a product developer to choose which implementation will be the best fit on your platform. This will depend on the product's requirements and resources. This is not a decision we can help you take, as we do not know your project.

Best regards,
Jørgen

Hi Jørgen Holmefjord ,

Thanks for your reply.

We are currently trying to integrate the matter SDK with our application which internally uses NRF 52840 SOC for thread communication.

1. Can you kindly let us know the link for the reference controller implementation?

You can have a look at the "Configure the CHIP Tool for Linux or macOS" documentation in nRF Connect SDK. This has a link to the release artifacts of chip-tool.
