All proses runing well, but i can't get connection string to create connection to server. Please help me, thanks for responses

Nb
i am using Symbia 3rd FP1 ME SDK, and 6120Clasic as device.

Is there a reason to go for such a short UUID like 9? Have you tried a long private one already?

[hendrawan.ashari]

yes i have try
private final static UUID uuid = new UUID("A55665EE9F9146109085C2055C888B38", false);

but same.

Do you get an exception, where? Or, is not found any service? Are you sure your service is advertised? As you are connection to an emulator, is it connected to a real Bluetooth adapter?
