Introduction
1 Introduction
This document provides information on the Combined AV Headset application that accompanies BlueLab™ v3.2.
This document describes how to compile, download and run the application.
The application demonstrates to product developers the features of _дмЙ`зкЙ»PJjмднбгЙЗб~. The application
is a starting point for product development programs. It is envisaged that product developers may define their
own Man Machine Interface (MMI) and add such features as battery monitoring to create a finished end-product.

3 Target Hardware
Target Hardware
The target hardware is CSR’s BlueCore3-Multimedia Development Board (DEV-PC-1307 Rev C). The user will
also need a suitable AV source capable of providing a Bluetooth
audio stream.
Note: CSR’s BlueCore3-Multimedia Development Board (DEV-PC-1307 Rev A) is not suitable to run this
application. The microphone input circuit does not work on this revision of the board.

Combined AV Headset Application
5 Combined AV Headset Application
When BlueLab v3.2 has been successfully installed, the Combined AV Headset application can be built and
executed using the application source code, shipped with BlueLab v3.2.
This section guides you step-by-step through the process of building and executing this application.
The application implements the following profiles:
! Headset Profile
! Handsfree Profile
! Advanced Audio Distribution Profile
! Audio/Video Remote Control Profile
This enables stereo music to be streamed to the headset with the ability to accept and make telephone calls via a
Bluetooth-enabled mobile phone.
5.1 Building the Combined Headset Application
Step 1: Connect BlueCore3-Multimedia Development Board
1. Connect your BlueCore3-Multimedia Development Board to your PC per the instructions supplied with
the development kit.
2. Ensure that you have connected the mini-USB connection and the SPI connection.
3. Turn on the board and ensure that the jumpers are configured as shown in Figure 5.1.
