write Received Packet To Serial

Writes the last packet received by the radio to serial in JSON format.

radio.writeReceivedPacketToSerial();

This should be called within a callback to on data packet received.

Data received format

The format for received data when these send functions are used:

• 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"}

Example

When radio data is received (after pressing the A button on the second micro:bit), this program sends temperature data to the serial port.

input.onButtonPressed(Button.A, () => {
    radio.sendNumber(input.temperature());
    radio.sendValue("temperature", input.temperature());
    radio.sendString("It's warm now");


});
radio.onReceivedNumber(function (receivedNumber) {
    radio.writeReceivedPacketToSerial();
});

Sample output to serial when A button pressed:

{"t":323,"s":0,"v":27}
{"t":325,"s":0,"n":"temperature","v":27}
{"t":326,"s":0,"n":"It's warm now"}
