Hi! I have problem with next:

  1. I do close connect with BluetoothConnection and recive next exception to RX onError ->
    com.github.ivbaranov.rxbluetooth.exceptions.ConnectionClosedException Can't read stream
    at com.github.ivbaranov.rxbluetooth.BluetoothConnection$1.subscribe(BluetoothConnection.java88)

  2. I do dispose to observeStringStream
    I again received above error in main thread.

Please fix problem with "UndeliverableException".
E/UncaughtException: io.reactivex.exceptions.UndeliverableException: java.io.IOException: read failed, socket might closed or timeout, read ret: -1

at io.reactivex.internal.operators.observable.ObservableDefer.subscribeActual(ObservableDefer.java:39)

I recive this error if use dispose before connect to device with error.

Maybe replace onError to tryOnError

Use 'RxJavaPlugins.setErrorHandler()`

fun connect(){
  rxBluetooth.observeConnectionState()
      .filter { it.state == BluetoothAdapter.STATE_CONNECTED }
      .subscribe(
        { onConnected() },
        { it.printStackTrace() })

  rxBluetooth.observeConnectionState()
      .filter { it.state == BluetoothAdapter.STATE_DISCONNECTED }
      .subscribe(
        { onDisconnected() },
        { it.printStackTrace() })
}

fun onConnected() {
  readDisposable = bluetoothConnection.observeByteStream()
      .subscribeOn(Schedulers.computation())
      .subscribe(
        { 
          // do something
         },
        { it.printStackTrace() })

    bluetoothConnection.send("111")
}

fun onDisconnected(){
  readDisposable.dispose()
}

then go to Bluetooth setup on phone -> tap connected device -> disconnect -> power off device -> app crash

        at java.lang.Thread.run(Thread.java:761) 

so I add RxJavaPlugins.setErrorHandler { it.printStackTrace() } to 'inherit Application class` then fixed it.
