Bluetooth low energy (LE) is a specification adopted by the Bluetooth SIG in April 2009 that enables low-power peripherals with a battery life of months to years to communicate with Bluetooth in handsets or other devices. Bluetooth LE opens up a new range of devices and applications such as on-body medical sensors and sports and fitness equipment. LE arose from a technology called Wibree (owned by Nokia) and was previously called ultra low power (ULP) Bluetooth.
