Nordic µBlu-equipped Casio G-SHOCK is first announced consumer Bluetooth low energy watch product

by K C Krishnadas, TechOnline India - March 30, 2011

Casio has revealed a Bluetooth low energy watch that employs Nordic µBlu nRF8001 Single-Chip-Connectivity to wirelessly link to Bluetooth v4.0-equipped smartphones and will join Casio's G-SHOCK brand of shock-resistant watches later this year

Ultra low power (ULP) RF specialist Nordic Semiconductor ASA today announces that the first consumer Bluetooth low energy watch product to be announced – a new Casio G-SHOCK shock-resistant watch that will be able to communicate Bluetooth v4.0-equipped smartphones – is based on a Nordic µBlue™ nRF8001
Single-Chip-Connectivity Bluetooth low energy solution.

The Casio G-SHOCK Bluetooth Low Energy Watch includes the following features: Time Correction from smartphone to watch (ensuring the watch always displays the correct time – anywhere in the world); Incoming Call, Email and SMS Alert notifications from smartphone to watch – including the ability to stop smartphone ring alerts from the watch; and a Finder Function that enables users to locate a misplaced phone by activating the alarm and vibration functions of their smartphone from a button-press on the watch.

The Nordic nRF8001’s class-leading ultra-low power performance (see 'About nRF8001' below) enables
Casio’s new G-SHOCK Bluetooth Low Energy Watch to offer a similar battery life to a conventional Casio wristwatch by being able to run from a single conventional CR2032 coin-cell watch battery for up to two years, while providing up to 12-hours per day of continuous wireless communication with Bluetooth v4.0-equipped smartphones and other devices.

The ability to use a coin-cell battery also means that the Casio G-SHOCK Bluetooth Low Energy Watch will weigh a similar amount (65g) to a conventional Casio G-SHOCK watch, and have a similarly small casing size (53.2 x 50.0 x 18.3mm) – all crucial for a product designed to be comfortably worn by users for long periods.

"Bluetooth low energy opens the door to completely new ways of using watches as new applications are developed for smartphones," said Etsuro Nakajima, Senior Manager within the Timepiece Division of Casio.
"Although this will begin with allowing watches and smartphones to wirelessly communicate, our expectation is that over time a new category of watch product that we call 'smart watches' will evolve and be able to connect to the wireless networks of various kinds of devices that support Bluetooth low energy."

"We are delighted to see a Nordic µBlue™ nRF8001 Single-Chip-Connectivity Bluetooth low energy solution employed in the first Bluetooth low energy commercial watch product to be announced," adds Geir Langeland, Nordic Semiconductor's Director of Sales & Marketing. "Especially given that the Nordic design team behind
the development of the nRF8001 has just been nominated 'Design Team of the Year' in the 2011 Annual Creativity in Electronics (ACE) awards organized by U.S. electronics design title EE Times."
