Bluetooth Low Energy (Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart[1]) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) aimed at novel applications in the healthcare, fitness, beacons,[2] security, and home entertainment industries.[3] It is independent of Bluetooth BR/EDR and has no compatibility, but BR/EDR and LE can coexist. The original specification was developed by Nokia in 2006 under the name Wibree[4], which was integrated into Bluetooth 4.0 in December 2009 as Bluetooth Low Energy.
