With Bluetooth Low Energy (BLE), smart devices are about to become ще розумніше. 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 easy gain 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 firmware and get examples using various development platforms-including iOS and Android app for 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
