LocalDevice local = LocalDevice.getLocalDevice();
String serviceUUID="14839ac47d7e415c9a42167340cf2339";

javax.microedition.io.Connection notifier = Connector.open(deviceURL);
StreamConnectionNotifier streamNotifier = (StreamConnectionNotifier) notifier;
StreamConnection connection = streamNotifier.acceptAndOpen();
System.out.println(" Connection accepted.");

OutputStream output = connection.openOutputStream();
InputStreamReader isr = new InputStreamReader(System.in);
BufferedReader reader = new BufferedReader(isr);

The control is stuck before "Connection accepted" line.

Hi, on PC software, we use Qt, and we use Java on Android platform. Sorry for that we can't help with connecting BLE using jvm. Have you ever connected to other BLE devices? And, it looks like you are using classic Bluetooth to connect but I'm not sure. Classic Bluetooth use the socket/stream to communicate.
