Understanding Core Configurations

Bluetooth Support
  • Updated

Introduction

Bluetooth® technology is implemented through a combination of software and hardware. This is often referred to as the Bluetooth Host (software) and Controller (hardware).

The two most prevalent implementations of the Bluetooth specification are Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR), adopted as version 2.0/2.1, and Bluetooth Low Energy (LE), adopted as version 4.0. Each implementation has different use cases, and each uses a different chipset to meet hardware requirements. Dual-mode chipsets are also available for devices to support both implementations.

Each implementation has a Core Configuration (defined in Volume 0, Part D of the Bluetooth Core Specification) that represents the minimum required Layers for both the Host and Controller portions, which together are considered a complete Bluetooth implementation. The following sections show diagrams of the most common Core Configurations and the Layer requirements for each. For complete information on Core Configurations, requirements, and conditionals, review Volume 0, Part D of the Bluetooth Core Specification.
