CSR Helps Make New NEC CASIO Mobile Communications MEDIASTM Smartphone Even Smarter

CSR plc (LSE:CSR)(NASDAQ:CSRE) today announced that NEC CASIO Mobile Communications has deployed CSR’s CSR8000TM connectivity platform along with CSR SynergyTM for Android software for its innovative new MEDIAS Android smart phone for winter 2011/12. The MEDIAS is the first Android phone capable of connecting via Bluetooth Low Energy (BTle) to a variety of low-power peripherals and accessories, such as the new NEC CASIO Mobile Communications “Remoppi”. The Remoppi is a small CSR-powered key ring remote that enables users to find lost phones or keys, and be alerted to incoming email or calls when their phones are out of reach.

“CSR was the only provider who could offer an innovative solution with everything we needed to quickly and seamlessly deliver connectivity with low-power consumption for our new smart phone and accessories,” said Mitsuhiro Hirashima, General Manager for NEC CASIO Mobile Communications. “This offering is one of a great many new innovations made possible by Bluetooth low energy that will change the way consumers interact with their mobile handsets, and make life more convenient for them.”

CSR Delivers Connectivity

The connectivity for the new MEDIAS is provided via the CSR8811TM Smart Ready Bluetooth 4.0 device and is the first commercially available Android smartphone to support the Phone Alert Status, Proximity, FindMe, Alert Notification and Time Bluetooth low energy profiles, which make it possible to connect to a number of new peripheral devices in use cases where battery life was previously a concern. Examples include: proximity tags such as the Remoppi; wrist watches that connect wirelessly to smart phones for time synchronisation or notification of incoming calls and last for years on the same battery; heart monitors that keep you in the zone when going for a run; and pedometers and other sporting devices that relay relevant information to users’ phones and more.

Many Bluetooth Low Energy accessories coming to market – including the NEC CASIO Mobile Communications Remoppi – are developed using CSR µEnergy® single-mode Bluetooth Low Energy platform’s CSR1000TM. The CSR µEnergy single platform has been optimised to support only Bluetooth Low Energy features, allowing products to not be limited by size constraints, but be cost-effective and power-efficient to run for years on a single-coin cell battery. The platform offers single-mode chips that complement CSR8000 dual mode offerings to provide a complete range of Bluetooth Low Energy solutions - making CSR one of the few companies that delivers an end-to-end Bluetooth Smart and Smart Ready solution.

CSR was the first company to qualify a Bluetooth low energy software solution for Android, with its CSR Synergy for Android product. The latest version of Android OS, as it stands today, does not yet have this Bluetooth low energy (BTle) software support built in. The CSR8811 is used in conjunction with CSR Synergy for Android systems software to enable the BTle support for the MEDIAS. The package speeds and simplifies the integration of multiple wireless technologies, speeding time-to-market and reducing development cost by including everything from low-level transport drivers, advanced connectivity stacks to high level UI add-ons for Android. The combination of the CSR8811 and CSR Synergy for Android enables NEC CASIO Mobile Communications as well as other third party application developers to innovate with their own unique BTle applications, bringing a richer feature set to end-users more quickly and seamlessly.

“The new NEC CASIO Mobile Communications MEDIAS smartphone represents an early example of how new-generation connectivity solutions and Bluetooth standards are helping to expand the application variety and usefulness of digital devices in fundamental ways,” said Ahmet Alpdemir, Senior Vice President for CSR Mobile. “The pairing of the MEDIAS smartphone with the Remoppi solves a frustrating challenge - losing cell phones or keys - and is one of many ingenious and truly helpful new use cases we’ll see over the coming months.”
