Class ButtonToButtonChannel

java.lang.Object
  org.openuat.channel.oob.ButtonChannel
      org.openuat.channel.oob.ButtonToButtonChannel

All Implemented Interfaces:

OOBChannel, ButtonInputHandler

public class ButtonToButtonChannel
extends ButtonChannel

This channel is an input channel. It implements the button input channel which listens to synchronous button presses on both devices. It therefore only implements the capture method and doesn't support the transmit method (it just does nothing).
This channel only records button presses and ignores button releases.
This channel has two different smallest time units: 400 ms and 300 ms. This means that from one list of captured intervals, two different candidate shared secrets will be generated. The byte[] returned by the capture method contains the concatenation of both candidates.
