##

|
|

|
|
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.
