GATT Service Details
Data in Bluetooth Low Energy is organized around units called 'GATT Services (http://adafru.it/iCp)' and 'GATT Characteristics'. To expose data to
another device, you must instantiate at least one service on your device.
Adafruit's Bluefruit LE Pro modules support some 'standard' services, described below (more may be added in the future).
UART Service
The UART Service is the standard means of sending and receiving data between connected devices, and simulates a familiar two-line UART
interface (one line to transmit data, another to receive it).
The service is described in detail on the dedicated UART Service (http://adafru.it/iCn) page.
