Bluetooth Low Energy Overview
Bluetooth
®
low energy technology
Bluetooth low energy technology
offers ultra-low power, state-of-
the-art communication capabilities
for consumer medical, mobile
accessories, sports and wellness
applications. Compared to classic
Bluetooth capabilities, Bluetooth low
energy is a connectionless protocol,
which significantly reduces the
amount of time the radio must be on.
Requiring only a fraction of the power
consumption of traditional Bluetooth
technology, Bluetooth low energy can
enable target applications to operate
on a coin cell for more than a year.

TI’s Bluetooth low energy solution
for sensor applications includes
the CC254x 2.4-GHz system-on-
chip (SoC), TI protocol stack, profile
software and application support.
The CC254x is an ultra-low power,
true one-chip integrated solution with
controller, host and application on
one device. It is a Flash-based and
flexible device, with ultra-low power
consumption, leading RF performance
and excellent coexistence with other
2.4-GHz devices. Combined with the
Bluetooth low energy protocol stack,
the CC254x forms the market’s most
flexible and cost-effective single-mode
Bluetooth low energy solution.
