# 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](/reference/radio/send-number) and [send value](/reference/radio/send-value). It does not work for [send string](/reference/radio/send-string) (although a string can be sent with [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-number) - ```{v:Value,t:MicrobitTimeAlive,s:Unused,n:"Name"}```
|
|
- [send string](/reference/radio/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.
|
|
|
|
```blocks
|
|
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}```
|
|
|
