Make micro:bit Radios Send and Receive

In this activity, a script will make one micro:bit repeatedly send messages through its radio.  Another micro:bit will run a different script that receives those radio messages and prints them to its terminal.   

This block diagram shows how the one-direction application will work.  The sender micro:bit prints its activity to the terminal, but that’s just so you can verify that its script is running.  The important part is that the sender micro:bit transmits radio messages to a receiver micro:bit.  That receiver micro:bit prints the messages it receives to its own terminal, where you can check and verify the radio data exchange.
