Overview of this book

Bluetooth Low Energy, or Bluetooth Smart, is Wireless Personal Area networking aimed at smart devices and IoT applications. BLE has been increasingly adopted by application developers and IoT enthusiasts to establish connections between smart devices. This book initially covers all the required aspects of BLE, before you start working on IoT projects. In the initial stages of the book, you will learn about the basic aspects of Bluetooth Low Energy—such as discovering devices, services, and characteristics—that will be helpful for advanced-level projects. This book will guide you through building hands-on projects using BLE and IoT. These projects include tracking health data, using a mobile App, and making this data available for health practitioners; Indoor navigation; creating beacons using the Raspberry Pi; and warehouse weather Monitoring. This book also covers aspects of Bluetooth 5 (the latest release) and its effect on each of these projects. By the end of this book, you will have hands-on experience of using Bluetooth Low Energy to integrate with smart devices and IoT projects.

Setting Up Your System to Write iOS Applications

Just like Android, iOS needs no formal introduction; however, we will go over some key knowledge factors related to it. iOS or iPhone OS is a mobile operating system which was developed by Apple Inc. and first introduced in June 2007 exclusively for Apple devices:

Note that one of the biggest differences between Android and iOS is that Apple designed iOS as an operating system, which was exclusively designed for Apple hardware. On the other hand, Android took more of a platform approach, which dictated a set of requirements and then the phone manufacturers could roll out devices adhering to these requirements. Also, this implies that iOS is closed source whereas Android is open source.

Just like Android, iOS also has a version history starting right from iPhone OS 1...
