Reducing the energy of Bluetooth low energy

Keywords:Bluetooth  v4.0  Special Interest Group 

There's more to a winning chip than just complying with Bluetooth v4.0. The Bluetooth Special Interest Group's (SIG) Bluetooth Core Specification Version 4.0 is not something to turn to for a little light reading. It's a highly detailed document running to six volumes totalling 2302 pages. Adopted in June 2010, the specification describes how a silicon vendor can design and make Bluetooth v4.0 chips that will communicate seamlessly with another manufacturer's chips. That's the key point of Bluetooth wireless technology: it's an open standard that ensures interoperability between wireless devices from different manufacturers, encouraging mass uptake.

Bluetooth low energy is a hallmark feature of Bluetooth v4.0 and has been designed to operate from small batteries with limited capacity. For the first time, Bluetooth low energy allows compact, low duty cycle wireless devices to link to the Bluetooth "ecosystem."
