BlueTunes2 Stereo Headset
Quick Start Guide
Additional Information
Using the Analogue-Audio Adaptor board
The Analogue Audio Adaptor solution from CSR makes it easy to design and manufacture
Bluetooth adaptor products for mobile handsets, MP3 players and Hi-Fi systems. This allows
products without built-in Bluetooth to connect to wireless headphones and speakers.
Connecting to wireless speakers or headphones
Screw the supplied helicoil antenna clockwise onto the base. The first time the audio
adaptor is turned on it will automatically start searching for Bluetooth headphones, speakers
or other A2DP sinks in range. When it finds one, it will try to pair with the device using a
fixed PIN code stored in Flash memory (as shipped, the PIN code is 8888). If the pairing
process is successful, it will set up an A2DP connection and start streaming music.
Pressing the button on the development board will delete any pairing information and start
the adaptor looking for further suitable A2DP sources. Make sure the A2DP sink device is in
pairing mode, otherwise it will not be visible.
LED patterns
The LED flashing indicates the state of the audio adaptor board:
Idle: the blue LED flashes; 100ms on, 1000ms off.
Discovering: both red and blue LEDs flash.
Streaming: the blue LED flashes; 1000ms on, 1000ms off.
Using the Voice Dongle
The Voice Dongle 1 is a true plug-and-play dongle that allows a Bluetooth headset to be
used for VOIP (Voice-Over-IP) calls.
Connecting the Voice Dongle to your headphones
1. Insert the dongle into a USB socket on your PC.
2. Ensure that the headset is in pairing mode, as described on page 2 of this
document.
3. Press and hold the button (clear plastic window) on the dongle until the LEDs
flash with a red-green-pause sequence (as oppose to red-green-red-green). This
flashing sequence indicates that the dongle is in pairing mode; the dongle should
now pair with your headset.
Pressing and releasing the button on the dongle causes the dongle to attempt pairing with
the last-paired device. In this state, the LEDs on the dongle flash in a red-green-red-green
sequence
