# UART Write Value
### ~hint
![](/static/bluetooth/Bluetooth_SIG.png)
For another device like a smartphone to use any of the Bluetooth "services" which the micro:bit has, it must first be [paired with the micro:bit](/reference/bluetooth/bluetooth-pairing). Once paired, the other device may connect to the micro:bit and exchange data relating to many of the micro:bit's features.
### ~
The [Bluetooth UART service](/reference/bluetooth/start-uart-service.md) allows another device such as a smartphone to exchange any data it wants to with the micro:bit, in small chunks.
With the Bluetooth UART service running, this block allows a micro:bit to send data to a Bluetooth connected device.
```sig
bluetooth.uartWriteValue("x", 42);
```
### Advanced
For more advanced information on the micro:bit Bluetooth UART service including information on using a smartphone, see the [Lancaster University micro:bit runtime technical documentation](http://lancaster-university.github.io/microbit-docs/ble/uart-service/)
