Bluetooth v4.0 introduced low energy technology to the Bluetooth Core Specification, enabling new Bluetooth Smart devices that can operate for months or even years on tiny, coin-cell batteries. Markets for these new devices include health care, sports and fitness, security, and home entertainment.
Bluetooth v4.0 is the most recent version of Bluetooth wireless technology. It includes a low energy feature that is the basis for Bluetooth Smart devices. A product bearing the Bluetooth Smart and Bluetooth Smart Ready logos must include Bluetooth v4.0, but must also meet additional criteria.
The Bluetooth SIG announced the formal adoption of Bluetooth Core Specification Version 4.0 in July 2010. By mid-2011, many devices based on this technology were under development and headed to market soon, including the first wave of Bluetooth Smart Ready mobile phones due out in late 2011.
This technology is creating new opportunities for developers and manufacturers of Bluetooth devices and applications, bringing to life entirely new markets for devices that are low-cost and operate with low power wireless connectivity.
