Rich Bluetooth platform liberates automotive developers

The pre-qualified 'RoadTunes' reference design provides the automobile industry with an exceptionally versatile hardware and software platform for the range of Bluetooth wireless applications - from hands free calling to advanced infotainment. Very easy to integrate, with an exceptionally low-cost eBOM, exhaustively tested to prove interoperability. Among the applications supported are:

• Hands-free calls
• Tuneable echo and noise cancellation
• Streaming digital music into infotainment system
• Wide Profile compatibility (HFP, PBAP, A2DP, AVRCP, DUN, ...)

Before release, the design has been tested for interoperability against a very large number of popular phones on (or coming on) the market. It can even download phonebooks for handsets' that do not support PBAP.

CSR's RoadTunes reference design is based around a single-chip Bluetooth solution with an embedded DSP and CODECs, which is offered in packaging suitable for ultra-compact plug-on modules, or easy integration into embedded auto electronics systems.  The choice delivers solutions that are suitable for all applications - from first-mount to aftermarket products, including PNDs.
