Write Value

Write a name/value pair and a newline character (\r\n) to the serial port.

serial.writeValue("x", 0);

Parameters

name is the string to write to the serial port
value is the number to write to the serial port

Example: streaming data

Every 10 seconds, the example below sends the temperature and light level to the serial port.

basic.forever(() => {
    serial.writeValue("temp", input.temperature())
    serial.writeValue("light", input.lightLevel())
    basic.pause(10000);
})

The send value function broadcasts string/number pairs. You can use a second micro:bit to receive them, and then send them directly to the serial port with write value.
