# raise alert to
|
|
|
|
The raise alert to function.
|
|
|
|
Raise an alert on a remote device.
|

## Bluetooth required

|
|
|
The functions in the ``devices`` namespace allow the BBC micro:bit to communicate with a separate (remote) device, such as a smartphone, over Bluetooth (Smart).
|
|

|
The set of supported events will depend on the remote device and the BBC micro:bit apps available for the remote device.
