Possibility to combine different protocols in single hex

[Dhaval Dalvadi]

With nrf52840 we have different protocols to add as per application. but is it possible  to include following for single application in single hex?

1) zigbee: coordinator, edge and router 
2) thread: border router, leader
3) matter 

user will be configuring via ble or any other way to select which protocol wants to use and which type of device for that selected protocol 


1) is it possible using nrf connect sdk?
2) is there any flash/ram size challenges to include all this protocol?
3) possible to use one or two protocols concurrently ex(zigbee and matter/thread)?

Hi, 

nRF52840 could not achieve your requirements mostly due to flash/RAM limitations. See 

• Matter hardware and memory requirements
• Zigbee memory requirements
• OpenThread memory requirements

In NCS, the Multiprotocol support achieves that the Thread and Zigbee protocols run another protocol in parallel, and the Matter and Zigbee applications are based on the Application Layer. So it can run two protocols concurrently. Of course, it will require many adaptations but technically it is possible. However, the main limitations are ROM and RAM.

Hi okay if ignore multiprotocol at same time 
is it doable to have all protocols added but depending on configuration it starts ?

The configs for the protocols would impact flash/RAM requirements.
