Bluetooth® low energy technology is an integral part the Bluetooth Core Specification from Bluetooth v4.0 onwards. Bluetooth low energy brings Bluetooth wireless connectivity to low cost, small battery operated devices that require months to years of battery lifetime. Bluetooth low energy will therefore enable a new and extended range of applications to benefit from Bluetooth wireless technology including watches, proximity tags, sports and fitness sensors, healthcare sensors and remote controls. Bluetooth low energy technology can be branded under the Bluetooth smart marks in accordance with guideline from the Bluetooth SIG.
Key features of Bluetooth low energy include:
Bluetooth low energy has official support in iOS and Android mobile platforms aswell as most desktop platforms including OSX, Windows 8 and Linux
