The sample chat app provided on backport-android-bluetooth source shows the 
same problem.

I should add that I've debugged this and I'm pretty sure the problem is when 
Rfcommsocket happens when it calls createNative(). Considering the 
"BLZ_WRAPPER" log, it's probably calling the native code correctly, but 
something wrong happens.

RfcommSocket.java

Line 155:
    /**
     * Creates a socket. You need to call this method before performing any
     * other operation on a socket.
     * 
     * @return FileDescriptor for the data stream.
     * @throws IOException
     * @see #destroy()
     */
    public FileDescriptor create() throws IOException {
        if (mFd == null) {
            mFd = createNative();
        }
        if (mFd == null) {
            throw new IOException("socket not created");
        }
        return mFd;
    }
