On Data Received

Note: This API has been deprecated! Use on data packet received instead.

Run part of a program when the micro:bit receives a number or string over radio.

radio.onDataReceived(() => { });

Example

This program keeps sending numbers that says how fast the micro:bit is slowing down or speeding up. It also receives numbers for the same thing from nearby micro:bits. It shows these numbers as a bar graph.

basic.forever(() => {
    radio.sendNumber(input.acceleration(Dimension.X));
})
radio.onDataReceived(() => {
    led.plotBarGraph(radio.receiveNumber(), 1023);
})
