Abstract

Bluetooth Low Energy Applications is an open-source Internet of Things (IoT) project. Code examples, errata and additional tips and references to interesting projects for the book "Develop your own Bluetooth Low Energy Applications for Raspberry Pi, ESP32 and nRF52 with Python, Arduino and Zephyr". It is built using C, Arduino, ESP32. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

Develop your own Bluetooth Low Energy Applications for Raspberry Pi, ESP32 and nRF52 with Python, Arduino and Zephyr

Bluetooth Low Energy (BLE) radio chips are ubiquitous from Raspberry Pi to lightbulbs. BLE is an elaborate technology with a comprehensive specification, but the basics are quite accessible.

The code is then downloaded into the directory bluetooth-low-energy-applications.

2. Objective

Code examples, errata and additional tips and references to interesting projects for the book "Develop your own Bluetooth Low Energy Applications for Raspberry Pi, ESP32 and nRF52 with Python, Arduino and Zephyr"

This project demonstrates how C, Arduino, ESP32 can be applied to a real-world Internet of Things (IoT) problem.

4. Technology Stack

CArduinoESP32

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

  • Arduino IDE / PlatformIO or a C compiler (gcc)
  • Target board where applicable
  • Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/koenvervloesem/bluetooth-low-energy-applications.git
cd bluetooth-low-energy-applications

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

  • Add a mobile dashboard using Blynk or Firebase
  • Store readings in a cloud database for history charts
  • Add alerts via SMS / Telegram when thresholds are crossed

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

  1. Which microcontroller / board and sensors are used and why?
  2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
  3. Where is the sensor data stored and visualised?
  4. How is power consumption managed?
  5. How would you secure the device and its communication?

9. Source Code & License
