Enabling a Radio Co-Processor using the Bluetooth® LE HCI Function#

Note: This section replaces AN1328: Enabling a Radio Co-Processor using the Bluetooth® LE HCI Function. Further updates to this application note will be provided here.

This document gives a short overview of the standard Host Controller Interface (HCI) and how to use it with Silicon Labs’ Bluetooth LE controller. First it briefly describes the HCI layer, the supported features, and explains the difference between a Network Co-Processor (NCP) and a Radio Co-Processor (RCP) project. It then lists the available vendor-specific commands and shows how to get started with the RCP Example project included in the Bluetooth LE SDK.

This document assumes that you have installed Simplicity Studio 5 and the Bluetooth LE SDK, and that you are familiar with creating, configuring, building, and flashing projects. If not, see the Bluetooth SDK Getting Started Guide.
