Internetworking with Bluetooth Low Energy

Abstract

Recent developments in the Bluetooth SIG have made Bluetooth Low Energy (LE), marketed as Bluetooth Smart, a strong contender for the underlying wireless technology in many IoT applications. The key strengths of Bluetooth LE are its very low power and widespread adoption. Recently, many indoor location applications have turned to Bluetooth LE. However, IEEE 802.11 and 802.15.4 based Zigbee have the lead in networking with IP. The new Bluetooth 4.2 Core Specification and Internet Protocol Support Profile improves the IP capabilities of Bluetooth. For networked IoT applications that demand the lowest power, Bluetooth LE may become the technology of choice.
