send Value

Send a string and number together by radio to other Calliope minis. The maximum string length is 8 characters.

radio.sendValue("name", 0);

Parameters

• name: a string that is the name of the value to send.
• value: a number that is the value to send.

Example: Broadcasting acceleration

This program sends your Calliope mini’s acceleration (amount it is speeding up or slowing down) in the x direction (left and right) to other Calliope minis. This kind of program might be useful in a model car or model rocket.

radio.setGroup(99)
input.onButtonEvent(Button.A, input.buttonEventClick(), () => {
    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);
});
