Bluetooth®and MSP430 Audio Source Reference Design
Quick Start Guide
The BT-MSPAUDSOURCE-RD is a TI Design that enables streaming out Bluetooth audio (SBC encoded)
using the SimpleLink™ CC2560 Bluetooth controller, the MSP430F5229 ultra-low power microcontroller,
and the TLV320ADC3101 low-power ADC plus a BQ24055 USB charge management device. This
reference design is a cost-effective Bluetooth audio implementation with full design files provided for
evaluation and end-product development. The software supported includes Stonestreet One Bluetopia®
Bluetooth stack (certified and royalty free).
This document will help you quickly get started on the BT-MSPAUDSOURCE out-of-the-box experience
demo.
This kit contains:
• One BT-MSPAUDSOURCE board
• One mini-USB cable
• One stereo audio cable with 3.5-mm plug connectors

Step 1: Set Remote Bluetooth Audio Sink Device Ready
Turn on the remote Bluetooth audio sink device and make sure it is ready to connect.
NOTE: The remote Bluetooth device must support the A2DP profile and sink role (for example, a
Bluetooth speaker or Bluetooth headphones).
NOTE: TI's Bluetooth and MSP430 Audio Sink Reference Design (BT-MSPAUDSINK board) can be
used as the remote Bluetooth device.
Figure 2. Bluetooth Audio Sink Device Examples
Step 2: Connect Audio Line-In
Connect an audio source device to the BT-MSPAUDSOURCE board by plugging in the stereo audio cable
to the 3.5-mm line-in jack (J39). The audio source can be any device with a 3.5-mm audio stereo output,
such as laptops, phones, and so on.

Step 3: Turn On the BT-MSPAUDSOURCE Board
Connect the mini-USB cable to the mini-USB port (J4) to apply power to the board. Turn on the board
using the PWR ON/OFF Switch (S2) so that the switch points towards the inside of the board.
NOTE: The board can also be powered from rechargeable batteries (J3), which can be purchased
separately.
Step 4: Automated Pairing and Connection Process
Check the green and red LEDs. These LEDs remain lit when the connection is established and the audio
is being played correspondingly.
NOTE: The BT-MSPAUDSOURCE automatically scans for Bluetooth audio sink devices available in
range. The device lists the Bluetooth audio sink devices in the order they were discovered
and gives priority to the BT-MSPAUDSINK boards. The BT-MSPAUDSOURCE will connect
to the first device available in this list. This procedure can take up to 10 seconds after turning
on the board.
Step 5: Listen to the Audio
Use the capacitive touch buttons to play and pause the audio.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
