The Bluetooth Special Interest Group has formally adopted Bluetooth Core Specification Version 4.0, which incorporates low energy technology. This means that low-power Bluetooth devices are likely to be available by the end of 2010.
Bluetooth low energy technology enables small battery-powered Bluetooth devices – such as healthcare and sports sensors – to communicate with Bluetooth-equipped mobile phones. These devices will be able to run for years on standard coin-cell batteries; a feat that existing Bluetooth devices are incapable of achieving.
