Received Signal Strength
Note: This API has been deprecated! Use on data packet received instead.
Find how strong the radio signal is, from -128 to -42.
(-128 means a weak signal and -42 means a strong one.)
The @boardname@ 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.
radio.receivedSignalStrength();
Returns
- a number between
-128and-42that means how strong the signal is.
Simulator
This function only works on the @boardname@, not in browsers.
Example
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());
});
