msg: a string to send by radio.

Watch this video to see how the radio hardware works on the micro:bit:

Example: Two-way radio

If you load this program onto two or more micro:bits, you can send a code word from one of them to the others by pressing button A. The other micro:bits will receive the code word and then show it.

radio.setGroup(1) input.onButtonPressed(Button.A, () => { radio.sendString("Codeword: TRIMARAN") basic.showString("SENT"); }) radio.onReceivedString(function (receivedString) { basic.showString(receivedString); })

A radio that can both transmit and receive is called a transceiver.
