import org.shokai.ibeacon.{IBeacon, Beacon};

class MainActivity extends Activity{

  lazy val iBeacon:IBeacon = new IBeacon(this)

  override def onCreate(savedInstanceState:Bundle){

    // capture all beacon packet

      Log.v("iBeacon", s"UUID=${beacon.uuid} Major=${beacon.major} Minor=${beacon.minor} RSSI=${beacon.rssi}")
    })


    // when beacon appear
    iBeacon.onDiscover((beacon:Beacon) => {
      Log.v("iBeacon", s"discover ${beacon}")
    })

    // specify UUID, Major, Minor (hex-code)
    iBeacon.onDiscover("805D6740-F575-492A-8668-45E553EB9DF2", null, null, (beacon:Beacon) => {
      Log.v("iBeacon", s"discover UUID=${beacon.uuid} Major=${beacon.major}")
    })

  }

}

Detect Region

// Region by RSSI
iBeacon.onRegion("805D6740-F575-492A-8668-45E553EB9DF2", "0001", "0001", Range(-70,-50), (beacon:Beacon) => {
  Log.v("iBeacon", s"region(-70~-50) UUID=${beacon.uuid} RSSI=${beacon.rssi}")
})

iBeacon.onFar("805D6740-F575-492A-8668-45E553EB9DF2", "0001", "0001", (beacon:Beacon) => {
  Log.v("iBeacon", s"far: ${beacon.uuid}")
})

iBeacon.onNear("805D6740-F575-492A-8668-45E553EB9DF2", "0001", "0001", (beacon:Beacon) => {
  Log.v("iBeacon", s"near: ${beacon.uuid}")
})

iBeacon.onImmediate("805D6740-F575-492A-8668-45E553EB9DF2", "0001", "0001", (beacon:Beacon) => {
  Log.v("iBeacon", s"immediate: ${beacon.uuid}")
})

Remove Listener

val eid = iBeacon.onBeacon((beacon:Beacon) => {
  Log.v("iBeacon", s"UUID=${beacon.uuid}")
})

iBeacon.removeListener(eid)
