on Received Number
Run part of a program when the @boardname@ receives a
number over radio.
radio.onReceivedNumber(function (receivedNumber) {})
Parameters
- receivedNumber: The number that was sent in this packet or
0if this packet did not contain a number. See send number and send value
Examples
Tell me how fast
This program keeps sending numbers that say how fast the @boardname@ is slowing down or speeding up. It also receives numbers for the same thing from nearby @boardname@s. It shows these numbers as a bar graph.
basic.forever(() => {
radio.sendNumber(input.acceleration(Dimension.X));
})
radio.onReceivedNumber(function (receivedNumber) {
led.plotBarGraph(receivedNumber, 1023);
})
What's the distance?
This program uses the signal strength from received packets to graph the approximate distance between two @boardname@s.
basic.forever(() => {
radio.sendNumber(0)
})
radio.onReceivedNumber(function (receivedNumber) {
led.plotBarGraph(
Math.abs(radio.receivedPacket(RadioPacketProperty.SignalStrength) + 42),
128 - 42
)
})
Troubleshooting
The ||radio:onReceivedNumber|| event can only be created once, due to the hardware restrictions.
The radio set group might need to be set, synchronized , before the radio events will function.
