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.

Preface

Designing the Monitoring App


The basic idea behind our setup is based on the system design we described in the Solution Design section previously. Our app behaves as the BLE + Wi-Fi Hub, reading data directly from the sensors planted on store/warehouse shelves and uploads it to the backend (Firebase) for monitoring purposes. 

A Note - We would be implementing a lot of functionality in this section. Please don't let that scare you. As a visual aid to give you a better understanding of the code that you would be implementing in this section, we have added a flowchart which outlines the flow of our App, towards the end of this section. Once you have implemented the code, we request you to review your code with the flowchart serving as a guidance tool. This will give you a much better understanding of the overall functionality of the App.

Following are the pre-requisites for this section,

  • Latest Android Studio
  • A Latest Android Device (Preferable Samsung Galaxy S8, since it has support for...
