Bluetooth Low Energy (BLE) Breakout Board Connects Arduino To iOS Or Android Devices
The Adafruit Bluefruit LE (Bluetooth Smart, Bluetooth Low Energy, Bluetooth 4.0) nRF8001 breakout board allows to build an easy to use wireless link between an Arduino and any compatible iOS or Android (4.3+) device.
It works by simulating a UART device beneath the surface, sending ASCII data back and forth between the devices, letting the user determine what data to send and what to do with it on either end of the connection.
Unlike traditional Bluetooth, BLE has no big contracts to sign and no notable hoops to jump through to design iOS peripherals that the user can legally design and distribute in the App Store, which makes it a great choice compared to classic Bluetooth which had (and still has) a lot of restrictions around it on the iOS platform.
With Bluetooth Low Energy (BLE), smart devices are about to become even smarter. This useful guide shows how this exciting wireless technology helps developers build mobile apps that share data with external hardware, and how hardware engineers can achieve easy and reliable access to mobile operating systems.
This book presents a robust, high-level overview of how devices use BLE to communicate with each other. You will learn valuable low-cost tools for developing and testing BLE-enabled mobile apps and embedded firmware and get examples using several development platforms—including iOS and Android for app developers and embedded platforms for product designers and hardware engineers.
