안드로이드 블루투스 클라이언트로 나는 내 arduino와 연결

Question

나는 내 블루투스 방패와 연결을 설정할 수 없다, 나는 다른 응용 프로그램과 함께 있었고, 장치가 작동하면 연결되어있는 빛에 의해 표시, 하지만이 응용 프로그램과 함께, 그것은 발생하지 않습니다. 이 메소드가 불량 소켓이 아닌 경우,이 메소드가 mmSocket.connect()라고 불리면 앱이 중단됩니다. tmp = mmDevice.createRfcommSocketToServiceRecord (MY_UUID);

UUID를 당신이 무엇을 제공하고있다) = 나는이 새로운 오전 도와주세요?

원격 장치에서 실행중인 모든 Bluetooth 프로필에 연결하려면 [연결하려는 서비스의 UUID]와 소켓 연결을 설정해야합니다.

다른 서비스의 UUID에 대한 자세한 내용은 www.bluetooth.org의 assigned numbers.pdf를 참조하십시오.
