Developed by world-leading wireless sports & fitness
monitoring developer and manufacturer - Dayton Industrial -
that also developed the world's first production-ready
Bluetooth low energy heart-rate belt last year - the
proximity key fob employs an ultra low power Nordic
Semiconductor µBlue™ nRF8002 Bluetooth low energy chip and
will support practically any proximity-based property
location or security application
Oslo, Norway - JUN 12, 2012- Ultra low power (ULP) RF
specialist Nordic Semiconductor ASA (OSE: NOD) today
announces that Hong Kong-headquartered Dayton Industrial Co.
Ltd - a world leading OEM/ODM (Original Equipment/Design
Manufacturer) of wireless monitors and associated products
(such as watches and bike computers) for top global sports &
fitness consumer brands - has now announced a Bluetooth® low
energy proximity key fob based on Nordic's µBlue™ nRF8002
System-on-Chip (SoC) that is less than half the size of a
credit card.
The nRF8002's class-leading ULP performance and
size will enable the
DaytonBluetoothlow energy proximity
key fob to run for around a year from a regular 3V CR2025
lithium coin cell battery under typical (daily) usage
conditions while featuring an extremely slim (0.5cm-thick)
and compact (4.9 x 3.2cm) plastic sensor housing that
features a single push button and two submerged LED status
lights (one red to signal alerts, and one green to signal
pairing status) within a product that weighs less than 40g.
There are also additional micro-vibrator and buzzer alert
options.
This production-ready product platform will allow OEMs
and developers to develop a whole new range of both standard
(Bluetoothv4.0 profile-based) and
non-standard (uniquely developed) proximity, property
location and security applications ('apps') for use
with devices that
employBluetoothv4.0 wireless
technology such as the latest iPad and the iPhone 4S.
Bluetoothlow energy is a hallmark feature
of the latestBluetoothv4.0
specification and if certain qualification requirements are
met can be used to
developBluetoothSmart devices (such
as wireless sensors, peripherals, and accessories) compatible
with anyBluetoothSmart Ready hub
product (e.g. A smartphone, tablet/computer, and other
gadget). (See
'AboutBluetoothlow
energy,BluetoothSmart,
andBluetoothSmart Ready'
below.)Within the
latestBluetoothv4.0 specification
there are currently two profiles applicable to
proximity-based property location and security:
