Bluetooth LE on the Raspberry Pi

The Raspberry Pi Model 3 has built-in support for Bluetooth Low Energy (BLE). BLE is the technology behind many fitness trackers and smartwatches, and allows small, low-power devices to transmit and receive information from a central computer or smartphone.

This tutorial gets you started with Bluetooth Low Energy using a Texas Instruments CC2650 SensorTag - these are small, robust, relatively cheap and do interesting things out of the box. You can buy one directly from TI, or in the UK they are available from RS and Farnell.
