A support ticket pointed out issues that they'd encountered when trying to follow this document: - `sendValue` only supports an 8 character string. This is documented in the `sendValue` docs but a longer string had been used here - Only `radio.onReceivedNumber` is used so the sample output is not consistent with the users experience. I've changed it so that all packets are handled

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"}
~hint
The serial number value sent in the packet is set to 0 unless transmission of the serial number is enabled with ||radio:radio set transmit serial number||.

Example
When radio data is received (after pressing the A button on
the second @boardname@), this program sends temperature data to the
serial port.
input.onButtonPressed(Button.A, function () {
radio.sendNumber(input.temperature())
radio.sendValue("temp", input.temperature())
radio.sendString("It's warm now")
})
radio.onReceivedNumber(function (receivedNumber) {
radio.writeReceivedPacketToSerial()
})
radio.onReceivedValue(function (name, value) {
radio.writeReceivedPacketToSerial()
})
radio.onReceivedString(function (receivedString) {
radio.writeReceivedPacketToSerial()
})
Sample output to serial when A button pressed:
{"t":323,"s":0,"v":27}
{"t":325,"s":0,"n":"temp","v":27}
{"t":326,"s":0,"n":"It's warm now"}
