What is Bluetooth Low Energy?
The internet of things will augment your brain.
– Eric Schmidt
At a very basic level IoT can be described as a network of things (physical devices, vehicles, buildings, and what not), which when augmented with sensors and servers enables these objects or things to collect and exchange data. A major driver behind this growth has been the advent of a comparatively lesser-known technology known as Bluetooth Low Energy (BLE).
In this chapter, we discuss this technology in the light of the following topics:
- An Overview of Bluetooth Low Energy
- The Need for Bluetooth Low Energy
- Bluetooth Low Energy versus Bluetooth Classic
- Architecture of Bluetooth Low Energy
- Profiles
- Services
- Characteristics
- Indications
- Notifications
- Bluetooth 5, Meshes, and Beacons
