SEV-E160S 내 핸드폰을 연결 한것을 확인 할 수 있다. (갤럭시 노트1 , 안드로이드 4.1.2)
노트북에서 블루투스통신을 하기 위해 c#으로 프로그램을 만들었다.
핵심은 InTheHand.Net.Personal.dll 이다. 이 DLL에서 제공해주는 라이브러리를 사용하여 블루투스 연결을 하였다.

전체적인 구조는 기본적인 통신 구조와 같다.
윈도우 프로그램은 서버 역활을 하며 접속을 기다린다.
여기서 UUID의 변경이 필요하다. 핸드폰과 핸드폰간의 블루투스 통신과
노트북과 핸드폰 간의 통신에서는 다른 UUID를 사용하기 때문이다.
드로에서 연결을 종료하게 되면 위와 같은 메시지가 나오며 다시 접속을 기다리게된다.
