Answer 1

Extending what pwc said about the UUID being 0x1101, this is the 16 bit version of the UUID as far as I can tell. I could not work out how to instantiate an UUID with a 16 bit UUID. But as this post says you can do it by:

private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805f9b34fb");

This worked for me to connect to a serial bluetooth module I bought from Deal Extreme

So what does all the rest of the UUID mean? I know 1101 means serial port protocol. – Thermaesthesia

@Thermaesthesia The rest of that UUID comes from the base UUID. – Hera

Answer 2

If the device is using serial port profile, then yes, it is simply:

0x1101

For other pre-defined options, see the list of pre-defined UUIDs as listed in javax.bluetooth:

UUID.
