Matter over Ethernet and Matter over Wi-Fi support

[Jayant Tang]

Hello DevZone,

Is it possible to support Matter over Ethernet and Matter over Wi-Fi at same time?

Since there are many Ethernet chips support in Zephyr.

Seems that the point is how to provision the device.

By the way, there is another question.

If there are some Wi-Fi APs with different SSID in one house, one LAN. Is it possible to provision a Matter device to a Wi-Fi AP that different to the Matter controller?

Best regards,

Jayant

Hi Jayant,

Is it possible to support Matter over Ethernet and Matter over Wi-Fi at same time?

It should be possible to implement Matter over Ethernet and Matter over Wi-Fi on the same device, but they can likely not run simultaneously. Also note that nRF Connect SDK does not support Matter over Ethernet so this needs to be implemented. It is possible to use some of the same code base as for Wi-Fi, but some modifications are needed. Here are some examples on needed modifications, but these are not all:

• A ConnectivityManager and DiagnosticDataProvider for Ethernet
• Expand the default configuration for Matter SDK in nRF Connect SDK to include Ethernet. https://github.com/nrfconnect/sdk-connectedhomeip/tree/master/config/nrfconnect/chip-module

If there are some Wi-Fi APs with different SSID in one house, one LAN. Is it possible to provision a Matter device to a Wi-Fi AP that different to the Matter controller?

In nRF Connect SDK, the Matter controller needs a direct link to the device which is provisioned. So if I understand your description correctly, what you describe is not possible.

Best regards,
