Class ClassicDiscovery

java.lang.Object

java.util.Observable

com.codename1.util.AsyncResource<Boolean>

com.codename1.bluetooth.classic.ClassicDiscovery

public class ClassicDiscovery
extends AsyncResource<Boolean>

Live handle of a running classic discovery (inquiry scan, ~12 seconds) returned by BluetoothClassic.startDiscovery(ClassicDiscoveryListener).

As an AsyncResource<Boolean> the handle resolves when discovery ends: with true when the inquiry finished (naturally or via stop()), or with a BluetoothException when the OS aborted it. cancel() is equivalent to stop().
