Abstract :
In 2010, the bluetooth special interest group published their Core Specification 4.0, including Bluetooth Low-Energy (BLE) technology, or Bluetooth Smart. This short-range radio breaks technical ground: it can run for years on batteries or scavenged power. It is a leading candidate to connect the "Internet of Things." This was updated to Core Specification v4.1 in late 2013 [1]. For more details, including reasons for decisions, see Bluetooth Low Energy, The Developers Handbook [2].
