AN1256: Using the Silicon Labs RCP with the OpenThread Border Router

Introduction

This application note from Silicon Labs guides software engineers in developing an OpenThread Border Router (OTBR). It details the process of using Silicon Labs' Radio Co-Processor (RCP) with the OpenThread Border Router software, enabling connectivity between Thread networks and IP-based networks like Wi-Fi or Ethernet.

The document covers essential aspects for building and installing both the RCP images and the OTBR itself, including manual installation and Docker container deployment on platforms like Raspberry Pi. It also provides information on OTBR configuration, network address translation (NAT64), and valuable OpenThread resources.

Key topics addressed include:

• Build and installation instructions for RCP images (UART and SPI).
• Build and installation instructions for the OpenThread Border Router (POSIX-based platforms, Docker).
• OTBR configuration details, including NAT64.
• Links to additional OpenThread resources for further learning and support.

This guide is intended for engineers familiar with OpenThread concepts and Silicon Labs' Simplicity Studio development environment.
