# Bluetooth UART Service
### ~hint
## ~hint

For another device like a smartphone to use any of the Bluetooth "services" which the @boardname@ has, it must first be [paired with the @boardname@](/reference/bluetooth/bluetooth-pairing). Once paired, the other device may connect to the @boardname@ and exchange data relating to many of the @boardname@'s features.

The Bluetooth UART service allows another device such as a smartphone to exchange any data it wants to with the @boardname@, in small chunks which are intended to be joined together. [UART[(https://en.wikipedia.org/wiki/Universal_asynchronous_receiver/transmitter) stands for Universal Asynchronous Receiver Transmitter and is one way in which serial data communications can be performed, usually between two devices connected by a physical, wired connection. The Bluetooth UART service emulates the behaviour of a physical UART system and allows the exchange of a maximum of 20 bytes of data at a time in either direction.
