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
| Bits | Size | Description |
|---|---|---|
| 0 - 1 | 2 | Unused, set to 0. |
| 2 - 7 | 6 | Minor device class. |
| 8 - 12 | 5 | Major device class. |
| 13 - 23 | 11 | Service 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.
QBluetoothDeviceInfo::CoreConfigurations QBluetoothDeviceInfo::coreConfigurations() const
Returns the configuration of the device. If device configuration is not set, basic rate device configuration will be returned.
This function was introduced in Qt 5.4.
See also setCoreConfigurations().
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.
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 and the complete list of UUIDs supported by the device is returned. DataIncomplete if additional service UUIDs are supported by the device and DataUnavailable if no service UUID information is available.
This function requires both the 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, serviceUuids() returns the complete list of service UUIDs supported by the device, otherwise only the partial or empty list of service UUIDs. To get a list of all 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 an active device.
See also isCached().
void QBluetoothDeviceInfo::setCoreConfigurations(QBluetoothDeviceInfo::CoreConfigurations coreConfigs)
Sets the CoreConfigurations of the device to coreConfigs. This will help to make a difference between regular and Low Energy devices.
This function was introduced in Qt 5.4.
See also coreConfigurations().
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().
bool QBluetoothDeviceInfo::operator!=(const QBluetoothDeviceInfo & other) const
Returns true if this object is different from other, or false otherwise.
