I know that this is the 16-bit UUID for the serial port profile (0x1101) promoted to a 128-bit UUID. This is what I had initially tried but incorrectly converted.

In my case, I am trying to connect to a Bluetooth device which I cannot assign a UUID to. All I know is that the device has a serial port service. I also do not know how to find the UUID of the device. Am I wrong in trying to connect to this device using the existing Android 2.0 Bluetooth API? It does not require pairing and can only communicate uses a serial port service (profile).
