# Write Value To Serial
|
|
|
|
Writes the data received by ``radio`` to serial in JSON format.
|
|
|
|
```sig
|
|
radio.writeValueToSerial();
|
|
```
|
|
|
|
### ~hint
|
|
|
|
This method only works for [send number](/reference/radio/send-number)
|
|
and [send value](/reference/radio/send-value). It does not work for
|
|
[send string](/reference/radio/send-string), although you can send a
|
|
string as part of [send value](/reference/radio/send-value).
|
|
|
|
### ~

|
### Data received format
|
|
|
|
The format for received data printed to serial is as follows:
|
|
|
|
- [send number](/reference/radio/send-number): ```{v:ValueSent,t:MicrobitTimeAlive,s:Unused}```
|
|
- [send value](/reference/radio/send-value): ```{v:ValueSent,t:MicrobitTimeAlive,s:Unused,n:"Name"}```
|
|
|
|
### Simulator
|
|
|
|
This function only works on the micro:bit, not in browsers.
|
|
|
|
### Examples
|
|
|
|
When ```radio``` data is received (after pressing the ``A`` button on
|
|
the second micro:bit), this program sends temperature data to
|
|
serial.
|
|
|
|
```blocks
|
|
input.onButtonPressed(Button.A, () => {
|
|
radio.sendNumber(input.temperature());
|
|
});
|
|
radio.onDataReceived(() => {
|
|
radio.writeValueToSerial();
|
|
});
|
|
```
|
|
Sample output to serial when ``A`` button pressed:
|
|
```{v:27,t:323,s:0}```
|
|
