Support Inquiry: Matter Bridge with Zigbee, BLE, and Wi-Fi Devices on nRF54L15

[Adarsh_N]

Hi,

I am currently working on the Matter ecosystem for an IoT home automation product. I have referred to the Nordic technical documentation on the Matter Bridge, available at the following link:
https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/matter/overview/bridge.html

From the documentation, I understand that it is possible to include non-Matter RF devices into the Matter ecosystem using a Matter Bridge. I have a few doubts regarding the implementation:

1. Is the nRF54L15 SoC sufficient to handle all types of non-Matter devices (such as Zigbee, BLE, and Wi-Fi), or do I need to use a dedicated SoC specifically for the Matter Bridge functionality?

2. Suppose I have the following devices in the setup:

   • Two Matter-supported devices over Thread

   • Five Matter-supported devices over Wi-Fi

   • Two non-Matter Zigbee devices

   • Two non-Matter Wi-Fi devices

   • Two non-Matter BLE devices

   In this case:

   • Do only the non-Matter devices need to connect to the Matter Bridge?

   • Or do both Matter and non-Matter devices need to connect to the bridge?

3. How many non-Matter devices can be connected and supported by a single Matter Bridge?

4. Does the Matter Bridge sample code provided in the Nordic SDK support integration for all RF protocols (Zigbee, BLE, Wi-Fi), or is it limited to BLE only?

5. Also how to include on Manufactures product in to my Matter Bridge, In real time I will be using different manufactures Non- Matter products. How we can pair the device and how to convert the commands of other Non Matter product.

I would appreciate it if you could provide clarification on these points.

Best regards,
Adarsh

Hi Adarsh,

Is the nRF54L15 SoC sufficient to handle all types of non-Matter devices (such as Zigbee, BLE, and Wi-Fi), or do I need to use a dedicated SoC specifically for the Matter Bridge functionality?

The nRF54L15 supports Zigbee, Thread, BLE, and Matter but not Wi-Fi. You will need a Wi-Fi companion IC, like the nRF7002. The Matter Bridge application does not currently support the nRF54L15.

Suppose I have the following devices in the setup:

• Two Matter-supported devices over Thread

• Five Matter-supported devices over Wi-Fi

• Two non-Matter Zigbee devices

• Two non-Matter Wi-Fi devices

• Two non-Matter BLE devices

In this case:

• Do only the non-Matter devices need to connect to the Matter Bridge?

• Or do both Matter and non-Matter devices need to connect to the bridge?

The Matter devices do not connect to the bridge. The Matter controller should add them to the Matter network just like a normal Matter device.

How many non-Matter devices can be connected and supported by a single Matter Bridge?

We do not have a set maximum number for this, but it will depend on memory requirements. In the Matter bridge application, the maximum is set to 16 by default, but this can be changed with the Kconfig option CONFIG_BRIDGE_MAX_BRIDGED_DEVICES_NUMBER. If you add more protocols to the bridge, you will not be able to have as many devices due to memory constraints.

Does the Matter Bridge sample code provided in the Nordic SDK support integration for all RF protocols (Zigbee, BLE, Wi-Fi), or is it limited to BLE only?

The Matter bridge application only supports BLE devices out of the box. You will have to add support for other protocols yourself, as described in Adding support for a proprietary protocol.

Also how to include on Manufactures product in to my Matter Bridge, In real time I will be using different manufactures Non- Matter products. How we can pair the device and how to convert the commands of other Non Matter product.

Can you provide some more information about the non-Matter products?

The application currently supports the following Matter device types: On/Off Light, On/Off Light Switch, Generic Switch, Temperature Sensor, and Humidity Sensor. Regarding Bluetooth services, it supports the LED Button Service and the ESP Peripheral. For other device types or services, you must add them to the code. See Adding support for a new Matter device type and Adding support for a new Bluetooth LE service for more information on this.

Best regards,

Hi, 

Suppose I'm using IOT Smart Bulb of Phillips which is not a Matter Supported product, As per the theoretical data I need to pair my Bulb in to Matter Ecosystem. Also this bulb is working on Wi-Fi RF signal. So It is possible for include this in the Matter Bridge. Also if suppose same way I need to  add any other non Matter IOT products in to my Matter ecosystem whether it can be possible?
   

Also I need a clarification like whether this on/off light, on/off light switch, generic switch, Temperature sensor and Humidity whether I can add the Smart Bulb in to my ecosystem using the existing sample code. How we can get the other third party manufactures product commands. Also how we can get if the product is encrypted. 

Whether the sample code is only supported to Nordic SOC as an POC level?

Kindly explain detail on this. I want the clarification whether I can add all the existing Non Matter IOT RF supported products in to Matter Ecosystem using Matter Bridge?
