Member Function Documentation

QBluetoothDeviceInfo::QBluetoothDeviceInfo ()

Constructs an invalid QBluetoothDeviceInfo object.

QBluetoothDeviceInfo::QBluetoothDeviceInfo ( const QBluetoothAddress & address, const QString & name, quint32 classOfDevice )

Constructs a QBluetoothDeviceInfo object with Bluetooth address address, device name name and the encoded class of device classOfDevice.

The classOfDevice parameter is encoded in the following format

BitsSizeDescription
0 - 12Unused, set to 0.
2 - 76Minor device class.
8 - 125Major device class.
13 - 2311Service class.

QBluetoothDeviceInfo::QBluetoothDeviceInfo ( const QBluetoothDeviceInfo & other )

Constructs a QBluetoothDeviceInfo that is a copy of other.

QBluetoothDeviceInfo::~QBluetoothDeviceInfo ()

Destroys the QBluetoothDeviceInfo.

QBluetoothAddress QBluetoothDeviceInfo::address () const

Returns the address of the device.

bool QBluetoothDeviceInfo::isCached () const

Returns true if the QBluetoothDeviceInfo object is created from cached data

bool QBluetoothDeviceInfo::isValid () const

Returns true if the QBluetoothDeviceInfo object is valid, otherwise returns false.

MajorDeviceClass QBluetoothDeviceInfo::majorDeviceClass () const

Returns the major device class of the device.

QByteArray QBluetoothDeviceInfo::manufacturerSpecificData ( bool * available = 0 ) const

Returns the manufacturer specific data. If available is not 0 it is set to true if manufacturer specific data is available; otherwise it is set to false.

Unsupported on all platforms at this time. Always return QByteArry();

See also setManufacturerSpecificData().

quint8 QBluetoothDeviceInfo::minorDeviceClass () const

Returns the minor device class of the device.

QString QBluetoothDeviceInfo::name () const

Returns the name assigned to the device.

qint16 QBluetoothDeviceInfo::rssi () const

Returns the signal strength when the device was last scanned

See also setRssi().

ServiceClasses QBluetoothDeviceInfo::serviceClasses () const

Returns the service class of the device.

QList<QBluetoothUuid> QBluetoothDeviceInfo::serviceUuids ( DataCompleteness * completeness = 0 ) const

Returns the list of service UUIDS supported by the device. If completeness is not 0 it will be set to DataComplete if the returned list is the complete list of UUIDs supported by the device. DataIncomplete if additional service UUIDs are supported by the device and DataUnavailable if no service UUID information is available.

This function requires both Bluetooth devices to support the 2.1 specification.

See also setServiceUuids().

DataCompleteness QBluetoothDeviceInfo::serviceUuidsCompleteness () const

Returns the completeness of the service UUID list. If DataComplete is returned then serviceUuids() will return a complete list of service UUIDs supported by the device. Otherwise serviceUuids() will only return a partial or empty list of service UUIDs. To get a full list of services supported by the device a full service discovery needs to be performed.

void QBluetoothDeviceInfo::setCached ( bool cached )

Used by the system to set the cached flag if the QBluetoothDeviceInfo is created from cached data. Cached information may not be as accurate as data read from a live device.

See also isCached().

void QBluetoothDeviceInfo::setManufacturerSpecificData ( const QByteArray & data )

Sets the manufacturer specific data returned by Extended Inquiry Responses to data.

Unsupported on all platforms at this time.

See also manufacturerSpecificData().

void QBluetoothDeviceInfo::setRssi ( qint16 signal )

Set the signal strength value, used internally.

See also rssi().

void QBluetoothDeviceInfo::setServiceUuids ( const QList<QBluetoothUuid> & uuids, DataCompleteness completeness )

Sets the list of service UUIDs to uuids and the completeness of the data to completeness.

See also serviceUuids().

QBluetoothDeviceInfo & QBluetoothDeviceInfo::operator= ( const QBluetoothDeviceInfo & other )

Makes a copy of the other and assigns it to this QBluetoothDeviceInfo object.

bool QBluetoothDeviceInfo::operator== ( const QBluetoothDeviceInfo & other ) const

Returns true if the other QBluetoothDeviceInfo object and this are identical
