The functions in the ``radio`` namespace allow the BBC micro:bit to communicate with other micro:bits.

|
||||||
|
|
||||||
This API does not contain any form of encryption, authentication or authorization. It's purpose is solely for use as a teaching aid to demonstrate how simple communications operates, and to provide a sandpit through which learning can take place.
|
|
||||||
|
|
||||||
For serious applications, BLE should be considered a substantially more secure alternative.
