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 and send value. It does not work for send string (although a string can be sent with send value).
Data received format
The format for received data printed to serial is as follows
- send number -
{v:ValueSent,t:MicrobitTimeAlive,s:Unused} - send value -
{v:Value,t:MicrobitTimeAlive,s:Unused,n:"Name"} - send string -
{}(currently unavailable)
Important Security Consideration
The functions in the radio namespace allow the BBC micro:bit to communicate with other micro:bits.
This API does not contain any form of encryption, authentication or authorization. It's purpose is solely for use as a teaching aid to demonstrate how simple communications operates, and to provide a sandpit through which learning can take place.
For serious applications, BLE should be considered a substantially more secure alternative.
radio.writeValueToSerial()
Parameters
- None
Examples
When radio data is received (after pressing A button on 2nd micro:bit), output temperature data to serial.
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}
