2- OpenThread Border Router CPC setup for Matter and Zigbee CMP Development

Summary

• Prerequisites
• CPC daemon and runtime libraries
• Building Host Programs
• NCP RCP firmware (CMP over UART)
• Configure and Run Host Services
• Create an OpenThread Network
• Matter over Thread support

Written on February 13th 2024 Built on Ubuntu Desktop for Raspberry 22.04.3 LTS

Purpose of this guide

This guide aims to help devloppers get started with Matter Gateway developement, but with support for Zigbee in a concurrent Multi Protocol architecture

It provides guidance on how to build and run an OpenThread Border Router from scratch on a Raspberry Pi 4 that supports Matter operations

As well as running a Zigbee Host that communicates over CPC (CoProcessor Communication)

This particular guide covers the build and use of CPC for OTBR Host to RCP communication; and Zigbee Host to NCP communication

CPC allows for multi protocol operation on the Co Processor side, enabling Zigbee and Thread Networking using only one device

This guide is based out of AN1333
