Multimedia Bluetooth drives hands-free design

Example design features full hardware and software components, including source code to allow designers to fully customise their end designs for hands-free kits.

RoadTunes from CSR is a feature rich, fully interoperable Bluetooth hands-free package for personal navigation devices (PNDs) and in-car systems.

Designed to provide OEMs with a faster time to market, RoadTunes boasts a less than six-week average integration time and at US $6 is available from today at the industry's lowest cost.

CSR's example design features full hardware and software components, including source code to allow designers to fully customise their end designs.

Based on CSR's market leading BlueCore5-Multimedia silicon, RoadTunes is a low power, fully interoperable design with a powerful RISC and DSP processor.

The design incorporates both CSR Clear Voice Capture (CVC) and third party echo cancellation technologies.

BlueCore5-Multimedia also features Bluetooth v2.1 for simple pairing and best in class audio codec with a signal to noise ratio of -95dB.

CSR has designed RoadTunes to allow OEMs to integrate Bluetooth connectivity quickly, enabling a faster time to market with an easy Plug-In concept.

Incorporating Bluetooth Embedded Control Interface (BECI) guidelines, RoadTunes allows for easy integration via a simple interface/API.

With almost no host MIPS required, RoadTunes takes the stress out of incorporating wireless connectivity in embedded and aftermarket automotive devices.

The average time to integrate RoadTunes on a device is less than six weeks and does not require prior in-depth Bluetooth experience.

RoadTunes allows the simultaneous pairing of up to eight Bluetooth devices, and controls safely a vast array of functions through numerous voice prompts.

As it also offers multiple profile support (including A2DP, AVRCP, HFP, PBAP, DUN and SPP), devices designed around RoadTunes can offer full Bluetooth connectivity including simultaneous audio, remote control of devices and hands-free operation.

In addition to allowing users to pair up to eight devices, RoadTunes also enables three-way calling and automatic reconnection on start-up.

With multi profile support, RoadTunes provides users with the power to access a variety of functions including last number redial, mute, voice dialling, phone book and even call history download (SIM/memory).

As a complete solution, RoadTunes has been tested against the highest number of phones in, or about to appear in, the market.

CSR provides all of its customers with the entire list of phones that the design has been tested against.

According to Rafik Jallad, Vice President of CSR's Automotive Strategic Business Unit: "The Bluetooth automotive market has experienced an enormous growth rate and we are confident that this will continue over the next two to three years".

"RoadTunes perfectly addresses the needs for both the PND and factory fitted markets, providing designers with the ability to integrate Bluetooth connectivity easily and quickly with superior audio quality and a wide range of functions".

"RoadTunes enables designers to get fully interoperable products to market faster and with the lowest cost".

"It simply makes it easy to add Bluetooth hands-free to any device that has a host processor" CSR's RoadTunes is available in packages with external Flash memory, Plug n Go, and Plug n Go AEC-Q100 (automotive qualified package).
