You’re interested in what all this BLE stuff is about, anyways? Let Adafruit’s lead Engineer, Kevin “KTOWN” Townsend (a.k.a “50 Ohm”) guide you in this detailed tome. KTOWN teamed up with Akiba (a.k.a “Wireless EL blinky guy”) to throw down all their knowledge in this book. Getting Started with Bluetooth Low Energy: Tools and Techniques for Low-Power Networking by Kevin Townsend, Carles Cufí, Akiba & Robert Davidson is the only BLE book you’ll ever need at your side.
With Bluetooth Low Energy (BLE), smart devices are about to become even smarter. This practical guide demonstrates how this exciting wireless technology helps developers build mobile apps that share data with external hardware, and how hardware engineers can gain easy and reliable access to mobile operating systems.
This book provides a solid, high-level overview of how devices use BLE to communicate with each other. You’ll learn useful low-cost tools for developing and testing BLE-enabled mobile apps and embedded fimware and get examples using various development platforms–including iOS and Android for app developers and embedded platforms for product designers and hardware engineers.
Understand how data is organized and transferred by BLE devices
Explore BLE’s concepts, key limitations, and network topology
Dig into the protocol stack to grasp how and why BLE operates
Learn how BLE devices discover each other and establish secure connections
Set up the tools and infrastructure for BLE application development
Get examples for connecting BLE to iPhones, iPads, Android devices, and sensors
Develop code for a simple device that transmits heart rate data to a mobile device
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
