Write Value To Serial

Writes the full data received data via radio to serial in JSON format.

Note - This method only works for send number and send value. It does not work for send string (although a string can be sent with send value).

radio.writeValueToSerial();

Data received format

The format for received data printed to serial is as follows

• send number - {v:ValueSent,t:MicrobitTimeAlive,s:Unused}
• send value - {v:Value,t:MicrobitTimeAlive,s:Unused,n:"Name"}
• send string - {} (currently unavailable)

Simulator

This function only works on the micro:bit, not in browsers.

Examples

When radio data is received (after pressing A button on 2nd micro:bit), output temperature data to serial.

input.onButtonPressed(Button.A, () => {
    radio.sendNumber(input.temperature());
});
radio.onDataReceived(() => {
    radio.writeValueToSerial();
});

Example output to serial when A button pressed:
{v:27,t:323,s:0}
