Develop your own Bluetooth Low Energy Applications (1 ed)

Develop your own Bluetooth Low Energy Applications: for Raspberry Pi, ESP32 and nRF52 with Python, Arduino and Zephyr (1 ed)

This book shows you the ropes of BLE programming with Python and the Bleak library on a Raspberry Pi or PC, with C++ and NimBLE-Arduino on Espressif's ESP32 development boards, and with C on any of the development boards supported by the Zephyr real-time operating system, including Nordic Semiconductor's nRF52 boards.

Bluetooth Low Energy (BLE) radio chips are ubiquitous, from the Raspberry Pi to light bulbs. BLE is a developed technology with extensive specifications, but the basics are quite accessible.

A step-by-step, systematic approach will guide you toward mastering this wireless communication technique, which is essential for working in low-power applications.

In this book, you will learn how to:

• Discover BLE devices around you by listening to their announcements.
• Create your own BLE devices by announcing data.
• Connect to BLE devices such as heart rate monitors and proximity sensors.
• Create secure connections with BLE devices using encryption and authentication.
• Understand and apply BLE service and profile specifications.
• Repurpose a BLE device with exclusive execution and control it with your own software.
• Make your BLE devices use as little power as possible.
• This book shows you the ropes of BLE programming with Python and the Bleak library on a Raspberry Pi or PC, with C++ and NimBLE-Arduino on Espressif's ESP32 development boards, and with C on any of the development boards supported by the Zephyr real-time operating system, including Nordic Semiconductor's nRF52 boards.

You'll start with a little theory and develop code. After reading this book, you'll know enough to create your own BLE applications.
