GATT Service Details
Data in Bluetooth Low Energy is organized around units called 'GATT Services' 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 page.
