Check the framework for sending data here: Android sample bluetooth code to send a simple string via bluetooth

The interesting part is: outputStream.write(s.getBytes());

That should become something like this: outputStream.write(new byte[]{(byte) 0x80, (byte) 0xF1, (byte) 0x98, 0x01, (byte) 0xC1, 0x33});
