Service discovery failed exception using Bluetooth on Android안드로이드
좋아, 내가 과거 2 ~ 3 일 주제를 많이 읽어 봤는데 아무것도가 보인다 이 질문을했습니다.
andriod 장치에 대한 PC 측 서버를 작성 중입니다. 일부 정보와 일반적인 디버깅을 교환하기위한 것입니다. 결국 SPP 장치에 연결하여 마이크로 컨트롤러를 제어하게 될 것입니다.
다음 (Android to PC)를 사용하여 rfcomm 채널 11에 연결하고 내 안드로이드 장치와 내 PC간에 데이터를 교환합니다.
메쏘드 m = device.getClass(). getMethod ("createRfcommSocket", new Class [] {int.class}); tmp = (BluetoothSocket) m.invoke (device, Integer.valueOf (11));
전적으로 운이없는 createRfcommSocketToServiceRecord (UUID) 메소드를 시도했습니다.
PC 쪽에서는 Linux 용 C Bluez 스택을 사용하고 있습니다. 서비스 레코드가 PC에서 실행되고 있는지 verifty 수있는 '지역 검색 sdptool'외에도,

그리고 는 로그 캣 위해 나는이지고 있어요 어려운 질문과 많은 것을 읽는 것처럼 보이지만, 나는 잠시 동안이 문제를 해결하기 위해 노력해 왔고, 나는이 일을하기 위해 많은 다른 것들을 시도했다.
다시 말해서 서비스 검색 프로토콜을 사용하지 않고 작동하도록 할 수 있습니다. 여러 개의 UUID를 시험해 보았고 두 대의 컴퓨터에서 테스트를 해봤지만 HTC Incredible 만 테스트 할 수있었습니다.
BT 스택이 HTC Droid에서 작동하지 않는다는 소문이 들렸지 만 적어도 PC 상호 작용에는 해당되지 않습니다.
