The Wireless Cookbook

Download Chapter 10: Exploring Mesh Networking

Wi-Fi, Bluetooth, and LoRa are technologies that power our world, but building with them isn’t always straightforward. Connections drop, tutorials skip steps, and error messages don’t always help resolve problems.

Through a series of hands-on projects using Raspberry Pi and Linux, you’ll learn how wireless systems work, how to control them, and how to build tools that actually function in the real world. Each recipe is self-contained, reliable, and ready to adapt for your own projects.

Among the book’s many projects, you’ll build:

• A BLE audio receiver for high-quality wireless sound
• A battery-powered LoRa node with miles of range
• A mesh Wi-Fi network that reroutes itself
• A signal strength display with a mini TFT screen
• A wireless intrusion detection system and captive portal

Along the way, you’ll build a solid foundation in Linux networking, gain fluency in wireless protocols like 802.11, BLE, and LoRaWAN, and develop the confidence to design and deploy your own solutions.

Each recipe is built around a wireless challenge you’re likely to encounter and gives you the tools to solve it.

It’s wireless. It’s Linux. And with this book, it finally makes sense.
