radio.receivedSignalStrength();
This API has been deprecated! Use received packet instead.
Find how strong the radio
signal is, from -128
to -28
.
(-128
means a weak signal and -28
means a strong one.)
The micro:bit finds the signal strength by checking how strong it was the last time it ran the on received number function. That means it needs to run receive number first.
-128
and -28
that means
how strong the signal is.Measurement of the received signal strength is dependent on what version of micro:bit you have. The micro:bit boards prior to v2 can typically measure a signal strength up to -42
dBm. Now, v2 boards will measure a signal strength up to -28
dBm (typical).
This function only works on the micro:bit, not in browsers.
This example shows how strong the radio signal of the light level sender example is.
let x = 0;
radio.setGroup(99);
basic.forever(() => {
x = radio.receiveNumber();
basic.showNumber(radio.receivedSignalStrength());
});
