C++ QBluetoothServiceInfo::setServiceUuid方法代码示例

/*!
    Attempts to make a connection to the service identified by \a uuid on the device with address
    \a address.

    The socket is opened in the given \a openMode.

    For BlueZ, the socket first enters the \l ServiceLookupState and queries the connection parameters for
    \a uuid. If the service parameters are successfully retrieved the socket enters
    ConnectingState, and attempts to connect to \a address. If a connection is established,
    QBluetoothSocket enters Connected State and emits connected().

    On BlackBerry and Android, the service connection can directly be established
    using the UUID of the remote service. Therefore these platforms do not require
    the \l ServiceLookupState and \l socketType() is always set to
    \l QBluetoothServiceInfo::RfcommProtocol.

    At any point, the socket can emit error() to signal that an error occurred.

    Note that most platforms require a pairing prior to connecting to the remote device. Otherwise
    the connection process may fail.

    \sa state(), disconnectFromService()
