QDBusAbstractAdaptor 객체가 구현 된 dbus 인터페이스를 내 보내지 않습니다.

Question

Qt 및 해당 DBus 기능을 사용하여 BlueZ v5.5 용 페어링 에이전트를 구현하려고합니다.

나는 어댑터 클래스를 인스턴스화 할 때 매개 변수로 제공하는 구현 된 메소드 (PairingAgent)가있는 PairingAgentAdaptor 및 클래스를 호출하는 qdbusxml2cpp 도구로 생성되는 어댑터 클래스가 있습니다.

개체를 새 에이전트로 등록 할 수 있으며 BlueZ 데몬에서 내 에이전트가 등록되었다고 말합니다. 내 전화기를 컴퓨터와 연결하려고하면 BlueZ 데몬은 "객체 경로 '/ pairing/agent'에 'org.bluez.Agent1'같은 인터페이스가 없습니다."라고 말합니다.

내가 뭘 잘못하고 있는지 전혀 모르겠다. 나에게 약간의 힌트를 주시겠습니까?

Answer 1

나는 그것을 지금 얻었다. :)

나의 첫번째 실수는 :

PairingAgent pairingAgent; 
PairingAgentAdaptor pairingAgentAdaptor(&pairingAgent); 

bool registerSuccess = QDBusConnection::systemBus().registerObject(QString(AGENT_PATH), &pairingAgentAdaptor); 

이

bool registerSuccess = QDBusConnection::systemBus().registerObject(QString(AGENT_PATH), &pairingAgent); // NEVER the adaptor!!! 

내 두 번째 실수한다 : 나는 org.bluez.Agent1에 대한 잘못된 인터페이스를 얻었다. 올바른 대답은 다음과 같습니다.
