Bluetooth low energy or Bluetooth LE, marketed as Bluetooth Smart, is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group aimed at novel applications in the healthcare, fitness, security, and home entertainment industries.

Mobile operating systems including iOS, Android, Windows Phone and BlackBerry, as well as OS X, Linux, and Windows 8, natively support Bluetooth Smart.

I found software for Bluetooth 4.0 for windows 8 (64 bits) here http://support.lenovo.com/us/en/downloads/ds037617
