I try to write an app to communicate between different bluetooth devices, and I did it as official API Guides. Before I tried to make my device(installed the app, nexus s, v4.1.2) as a client connect to a remote device(nexus 7, v4.4.2) as a server, I got almost 10 uuids of the server device by fetchUuidsWithSdp() and getUuids(), by the way, there is no 00001101-0000-1000-8000-00805F9B34FB, which is mentioned in android reference. How to find out which uuid is the right one for SPP communication?
