Chapter 3 Exploring Bluetooth LE on the Arduino 101

Bluetooth Low Energy (BLE), originally started by Nokia as an in-house project called “Wibree,” has grown to become a standard in wireless communication protocols. Operating on the same frequency as classic Bluetooth, BLE offers decreased power consumption while maintaining a similar range.

Whereas classic Bluetooth is great for streaming audio and other applications that have a high data throughput, Bluetooth LE is primarily meant for applications that need to exchange only small amounts of data at a slower rate. This makes BLE an ideal choice for communications among low-power connected ...
