I would ignore the stopDiscovery error - its good that you're cancelling discovery before making your connection. Per the SDK docs:

Because discovery is a heavyweight precedure for the Bluetooth adapter, this method should always be called before attempting to connect to a remote device with connect(). Discovery is not managed by the Activity, but is run as a system service, so an application should always call cancel discovery even if it did not directly request a discovery, just to be sure.

So with that said, were you able to get the Bluetooth Chat example to work before you made any modifications to the code?

The UUID you want for SPP/RFCOMM is:

static UUID UUID_RFCOMM_GENERIC = new UUID(0x0000110100001000L,0x800000805F9B34FBL);

or defined another way (both accomplish the same thing).

static final UUID UUID_RFCOMM_GENERIC = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
