# write Value To Serial
Write the data received by radio to serial in JSON format.
```sig
radio.writeValueToSerial();
```
## ~ hint
**Deprecated**
This API has been deprecated! Use [write received packet to serial](/reference/radio/write-received-packet-to-serial) instead.
## ~
## 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:SerialNumber}```
- [send value](/reference/radio/send-value): ```{v:ValueSent,t:MicrobitTimeAlive,s:SerialNumber,n:"Name"}```
- [send string](/reference/radio/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.
```blocks
input.onButtonEvent(Button.A, ButtonEvent.Click, () => {
radio.sendNumber(input.temperature());
});
radio.onDataReceived(() => {
radio.writeValueToSerial();
});
```
Sample output to serial when ``A`` button pressed:
```Text
{v:27,t:323,s:0}
```
