IoT Projects with Bluetooth Low Energy

By: Madhur Bhargava

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.

Problem Statement and Solution Design


While designing any system, it is imperative to understand the following:

  • Which problem does the system address?
  • How do the various individual parts in the system communicate with each other or how does the flow of data take place in the system?

Not to bog you down with the details, we shall only elaborate on the essential parts and design the bare minimum system so that you can get an idea of data flow and overall system design. Let's understand the problem at hand first, by eventually coming up with a problem statement.

Apart from several other items, warehouses are also used for storing vegetables, food, and medicines. Specifically for these items, it is crucial to maintain a correct balance of the temperature and humidity; otherwise, there is a risk of major losses. Hence, a warehouse deploys specially designed monitoring systems, which continuously monitor the climate inside a warehouse. If anything goes awry, then these systems are capable of raising...
