@ -55,8 +55,10 @@ The hunter @boardname@ looks for beacons.
To determine how far away or how close they are, we use the signal strength of each radio packet sent by the beacons. The signal strength ranges from ``-128db`` (weak) to ``-42db`` (very strong).
```blocks
radio.onDataPacketReceived( ({ receivedNumber, signal }) => {
basic.showNumber(signal)
let signal = 0;
radio.onReceivedNumber(function (receivedNumber) {
signal = radio.receivedPacket(RadioPacketProperty.SignalStrength)
basic.showNumber(signal);
