Building a Bluetooth LE Hardware Companion App
Ahmed Bakir · Apress eBooks · 2018
In Chapter 5 , you dipped your toes into the world of embedded systems, to build an Arduino-based wireless door sensor. In this chapter, you will continue your hardware engineering journey, by developing the Bluetooth LE–based companion app for the door sensor. Bluetooth LE is an extremely popular radio-based communication protocol that allows devices to communicate at ranges up to 77 meters (~250 feet), with a very low-energy requirement, compared to other wireless communication methods (this is the LE part of Bluetooth LE). These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
