    \class QBluetoothDeviceDiscoveryAgent
    \brief The QBluetoothDeviceDiscoveryAgent class provides an API for discovering nearby
           Bluetooth devices.

    \ingroup connectivity-bluetooth
    \inmodule QtConnectivity

    To discovery nearby Bluetooth devices create an instance of QBluetoothDeviceDiscoveryAgent,
    connect to either the deviceDiscovered() or finished() signals and call start().

    \snippet snippets/connectivity/devicediscovery.cpp Device discovery

    To retrieve results asynchronously connect to the deviceDiscovered() signal. To get a list of
    all discovered devices call discoveredDevices() after the finished() signal is emitted.
*/

/*!
    \enum QBluetoothDeviceDiscoveryAgent::Error

    Indicates all possible error conditions found during Bluetooth device discovery.

    \value NoError          No error has occurred.
    \value PoweredOff       Bluetooth adaptor is powered off, power it on before doing discovery.
    \value IOFailure        Writing or reading from device resulted in an error.
    \value UnknownError     An unknown error has occurred.

    \enum QBluetoothDeviceDiscoveryAgent::InquiryType

    This enum describes the inquiry type used when discovering Bluetooth devices.

    \value GeneralUnlimitedInquiry  A general unlimited inquiry. Discovers all visible Bluetooth
                                    devices in the local vicinity.
    \value LimitedInquiry           A limited inquiry. Only discovers devices that are in limited

                                    Service Discovery is only done on one or two devices speeding up the
                                    service scan.  After the game has connected the device returns to
