What distinguishes the nrfconnect/sdk-connectedhomeip repositories from utilizing the chip/connectedhomeip repository directly for constructing Matter products?

[Anthony Shivakumar]

When employing the chip/connectedhomeip repository, I can successfully build without encountering any errors. However, when I follow the instructions outlined on this page: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/protocols/matter/getting_started/testing/thread_one_otbr.html and use the source code available here: https://github.com/nrfconnect/sdk-connectedhomeip/releases, I encounter unexpected errors during the build process.

Is there a method to seamlessly integrate the connectedhomeip repository with nRF SDK 2.4.2 to ensure compatibility and avoid these issues?

Hi, 

What version of the https://github.com/nrfconnect/sdk-connectedhomeip are you using? Please use the same version as the NCS and follow this guide Working with the CHIP Tool. 

Regards,
Amanda H.

Hi Amanda,

Thank you for your reply. I have progressed a bit further. I have created a video demoing what I have and what I have done.

https://youtube.com/live/x10PxXBbZr8

I am trying to connect using Bluetooth and WiFi.  I have one linux laptop, one nrf700DK and one nrf5340-DK. I want the matter controller to control the 70002-dk light switch example on and off. I am not able to get it to work. Perhaps you can help me out.

Hi, 

Please use the chip tool from https://github.com/nrfconnect/sdk-connectedhomeip and the same version as the NCS you are using.  

From https://youtu.be/x10PxXBbZr8?t=555, I see it still commissioned fail. 

Please check Commissioning into a Wi-Fi network over Bluetooth LE and make sure the commission is successful.

I have a video youtube.com/.../xd9S0ZlmL1c demonstrating the challenges I'm encountering when attempting to connect via WiFi using a Linux-based Matter controller.

Here's my issue: I'm working on using Matter over WiFi with a Linux computer as the Matter controller. I have three boards, which consist of two NRF700DKs and one 5340DK. I've successfully commissioned one of the NRF700DKs, but I'm facing difficulties commissioning the other.

Occasionally, I can control the LED with the device that has been commissioned using the Matter controller, but sometimes it doesn't work as expected. How can we go about troubleshooting these problems?

Additionally, I'm curious about the concept of the "node ID." If I have three Matter accessories, how do they determine their respective node IDs? Strangely, one of the NRF700DKs accepts node ID 1, but I'm struggling to get the other one commissioned. Any assistance would be greatly appreciated.

Also,
Regarding the NRF002 devices, one of them successfully commissions, but the other does not. I understand that node IDs need to be unique, but how do these devices determine which ID to assign when they are all awaiting commissioning? If it's a random assignment, it doesn't seem like an efficient way to troubleshoot for a couple of reasons:

    With many accessories, you might not know which ID is already taken.
    It becomes challenging to figure out why a unique node ID didn't commission an available accessory.

The only solution appears to be repeatedly trying different node ID numbers until one successfully commissions. Is there a more effective method for assigning node IDs?

Please provide the from both the device and the chip tool.

The node ID is defined by you when you pair the device, so you can set this to what you want the ID to be.
