Casio Bluetooth Low Energy Watch

Casio’s Bluetooth Low Energy Watch prototype employs Nordic µBlueTM nRF8001 Single-Chip-Connectivity to wirelessly link to Bluetooth v4.0-equipped smartphones, enabling time synchronization, incoming call or message alerts, and misplaced handset alarm activation. The ultra-low power consumption of the nRF8001 ensures up to 2-years of battery life from the watch’s CR2032 coin cell with 12-hours per day of continuous wireless communication.

Oslo, Norway – March 3, 2011 – Ultra low power (ULP) RF specialist Nordic Semiconductor ASA (OSE: NOD) today announces that a Bluetooth Low Energy Watch prototype developed by Casio Computer Co., Ltd., – shown at the International Consumer Electronics Show (CES) in Las Vegas, U.S. (see www.tinyurl.com/66bvb2y) – is based on a Nordic µBlueTM nRF8001 Single-Chip-Connectivity Bluetooth low energy solution.

The nRF8001′s class-leading ultra-low power performance enables Casio’s prototype watch to benefit from the advantages of Bluetooth wireless technology while offering a similar battery life to a conventional Casio wristwatch. As such the Casio watch prototype can run from a single conventional CR2032 button-cell watch battery for up to two years, while providing up to 12-hours per day of continuous wireless communication with any Bluetooth v4.0-equipped smartphone or other device – due to start arriving later this year.

Nordic has been at the forefront of the group that defined the Bluetooth low energy specification since becoming a foundation member of Nokia’s Wibree Alliance in 2006 (the Alliance became part of the Bluetooth Special Interest Group (SIG) in June 2007). Nordic contributed decades of expertise – gained in producing successive generations of class-leading proprietary and interoperable (ANT/ANT+) ULP wireless connectivity solutions within a field it pioneered – to Bluetooth low energy wireless technology that is now a hallmark of the latest Bluetooth v4.0 specification.

Bluetooth low energy has been designed from the outset to extend Bluetooth wireless connectivity to compact, coin cell-powered devices such as watches. By ensuring interoperability with Bluetooth v4.0-equipped devices such as smartphones (which will start to appear on the market later this year), conventional wristwatches now have the potential to be equipped with an expanding range of brand new wireless features that could create a new growth segment within the traditional wristwatch market (especially among young people who have tended to favor their cell phones over watches to, for instance, tell the time).

Casio’s Bluetooth Low Energy Watch prototype shown at CES demonstrated some of the new functionality that Bluetooth low energy will support, including:

  • Incoming call and message (including e-mail) alerts on the watch;
  • The ability to stop ring alerts from the watch;
  • The ability to locate a misplaced phone by activating the alarm and vibration functions of a smartphone from a button-press on the watch;
  • Time and date-synchronization from smartphone to watch (ensuring the watch always displays the correct date and time – even across different times zones).

“From 1974 when Casio released its very first digital wristwatch, we recognized that long battery life was crucial for end-user convenience and so commercial success,” explains Etsuro Nakajima, Senior Manager within the Timepiece Division of Casio. “Now, thanks to Nordic Semiconductor’s technology, our customers will soon be able to wear a Bluetooth low energy-enabled Watch every day like a regular wristwatch without having to worry about frequent recharging cycles.”

Nakajima continues: “We know Nordic Semiconductor is a pioneer of ultra-low power wireless connectivity and its expertise in this technology is evident in the power consumption performance of the nRF8001 that was superior to other Bluetooth low energy chips we assessed. This performance allowed us to develop our Bluetooth Low Energy Watch prototype and offer the same battery life from a conventional coin cell as one of our existing watches. And allied with Nordic’s excellent technical experience and support, is why we intend to continue with further collaboration with the company.”

“Casio’s Bluetooth Low Energy Watch is exactly the kind of application we imagined could be possible all those years ago when we embarked on the development of Wibree that led directly to Bluetooth low energy,” comments Geir Langeland, Nordic Semiconductor’s Director of Sales & Marketing. “It is an honor to have our technology incorporated into Casio’s first Bluetooth Low Energy Watch prototype and particularly satisfying to see the promise of Bluetooth low energy start to become a reality after five years of foundational work.”

Casio is encouraging enquiries from potential partner companies seeking to develop applications compatible with smartphones and other household devices in market segments such as sports and fitness, health, home entertainment, security (e.g. panic alarms), and remote monitoring.

About Nordic Semiconductor ASA

Nordic Semiconductor is a fabless semiconductor company specializing in ultra low power (ULP) short-range wireless communication.

Nordic Semiconductor’s nRF24xxx range of 2.4GHz transceiver and transmitter devices are aimed at applications including PC peripherals (wireless keyboards/mice/multimedia controllers), game controllers, intelligent sports equipment and wireless audio (for example, MP3 and portable CD player wireless headphones and wireless PC speakers).

Nordic is a member of the ANT+ Alliance and has successfully collaborated with ANT Wireless of Cochrane, Canada, since 2005. ANT devices such as the nRF24AP2 family – using Nordic 2.4GHz transceivers and the proven ANT protocol – have been used in millions of wireless sensor nodes across the world. ANT is perfectly suited for any kind of low data rate sensor network topologies in personal area networks (PANs) and practical wireless sensor networks (WSNs). ANT+ (built on the ANT protocol) facilitates interoperability between ANT+ Alliance member devices in application segments such as sports, wellness, and medical health sensors.

Nordic is an associate member of the Bluetooth SIG, and has contributed core expertise in ultra low power (ULP) RF design to Bluetooth® low energy wireless technology (formerly ultra low power Bluetooth). Bluetooth low energy is a short range RF communication technology featuring ultra low power consumption, a lightweight protocol stack and simple integration with Bluetooth chips. It is a hallmark feature of the latest Bluetooth Core Specification Version 4.0. The technology will support the next generation of RF communications by opening up many new opportunities for ULP wireless data links between suitably equipped mobile handsets or computers and small (typically coin cell) battery-powered devices such as sports, wellness, and medical health sensors.

Nordic’s products are all manufactured in state of the art semiconductor process technologies through strong, long-term relationships with world-best manufacturing facilities. Sales are primarily made through a carefully selected worldwide distribution network.
