/*!
    Attempts to connect to the service described by \a service.

    The socket is opened in the given \a openMode. The \l socketType() may change
    depending on the protocol required by \a service.

    The socket first enters ConnectingState and attempts to connect to the device providing
    \a service. If a connection is established, QBluetoothSocket enters ConnectedState and
    emits connected().

    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.
