Watch this video to see how the radio hardware works on the micro:bit:
send Value
Send a string and number together by radio
to other micro:bits.
The maximum string length is 8 characters.
radio.sendValue("name", 0);
Parameters
Example: Broadcasting acceleration
This program sends your micro:bit’s acceleration (amount it is
speeding up or slowing down) in the x
direction (left and right) to
other micro:bits. This kind of program might be useful in a model car
or model rocket.
radio.setGroup(99)
input.onButtonPressed(Button.A, () => {
radio.sendValue("acc", input.acceleration(Dimension.X))
})
This program receives the string and number sent by the last program. Then it shows them on the LED screen.
radio.setGroup(99)
radio.onReceivedValue(function (name, value) {
basic.showString(name);
basic.showNumber(value);
});
