write Value To Serial

Write the data received by radio to serial in JSON format.

radio.writeValueToSerial();

~ hint

Deprecated

This API has been deprecated! Use write received packet to serial instead.

~

Data received format

The format for received data printed to serial is as follows:

  • send number: {v:ValueSent,t:MicrobitTimeAlive,s:SerialNumber}
  • send value: {v:ValueSent,t:MicrobitTimeAlive,s:SerialNumber,n:"Name"}
  • send string: {t:MicrobitTimeAlive,s:SerialNumber,n:"Text"}

Examples

When radio data is received (after pressing the A button on the second @boardname@), this program sends temperature data to serial.

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

Sample output to serial when A button pressed:

{v:27,t:323,s:0}
