1 Introduction
1.1 Overview
This document describes the hardware design of K32L2B Bluetooth Low
Energy (Bluetooth LE) Audio System and software architecture (top-level
design) of Host Controller (K32L2B). This document is provided for those who
intend to have a systematic view of K32L2B Bluetooth LE Audio System. They
can also refer to relevant ANs if need more introduction about Dongle (
K32L2B Dongle
), Headset (
K32L2B Headset
) and OTA
(
K32L2B OTA
).
• Hardware introduction introduces the hardware composition of K32L2B Dongle and Headset, as well as the connection
diagram.
• Software introduction introduces audio data path and software framework.
1.2 Summary
This document provides necessary information on how to get started on the K32L2B Bluetooth LE Audio System based on FRDM-
K32L2B board and NxH3670 SDK boards.
Figure 1. NxH3670 wireless headset use case
The system consists of a Dongle and a Headset, using K32L2B as Host Controller.
• Dongle: The Dongle has a USB interface that connects to PC. Dongle is responsible for setting up a wireless audio link
with Headset.
• Headset: The Headset has a speaker, a microphone and some User Interface (UI) components, such as, buttons, sliders,
rotary switches and LED. Headset is responsible for receiving audio data sent from Dongle and sending the recorded
audio to Dongle.
