[since 5.5] QBluetoothDeviceInfo::QBluetoothDeviceInfo(const QBluetoothUuid &uuid, const QString &name, quint32 classOfDevice)▲
Constructs a QBluetoothDeviceInfo object with unique uuid, device name name and the encoded class of device classOfDevice.
This constructor is required for Low Energy devices on macOS and iOS. CoreBluetooth API hides addresses and provides unique UUIDs to identify a device. This UUID is not the same thing as a service UUID and is required to work later with CoreBluetooth API and discovered devices.
This function was introduced in Qt 5.5.
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.
On iOS and macOS this address is invalid. Instead deviceUuid() should be used. Those two platforms do not expose Bluetooth addresses for found Bluetooth devices and utilize unique device identifiers.
See Also▲
See also deviceUuid()
[since 5.4] 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▲
See also setCoreConfigurations()
[since 5.5] QBluetoothUuid QBluetoothDeviceInfo::deviceUuid() const▲
Returns a unique identifier for a Bluetooth device without an address.
In general, this uuid is invalid on every platform but macOS and iOS. It is used as a workaround for those two platforms as they do not provide Bluetooth addresses for found Bluetooth Low Energy devices. Every other platform uses address() instead.
This function was introduced in Qt 5.5.
See Also▲
See also setDeviceUuid()
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.
QBluetoothDeviceInfo::MajorDeviceClass QBluetoothDeviceInfo::majorDeviceClass() const▲
Returns the major device class of the device.
[since 5.12] QByteArray QBluetoothDeviceInfo::manufacturerData(quint16 manufacturerId) const▲
Returns the data associated with the given manufacturerId.
Manufacturer data is defined by the Supplement to the Bluetooth Core Specification and consists of two segments:
-
Manufacturer specific identifier code from the Assigned Numbers Company Identifiers document
-
Sequence of arbitrary data octets
The interpretation of the data octets is defined by the manufacturer specified by the company identifier.
The remote device may provide multiple data entries per manufacturerId. This function only returns the first entry. If all entries are needed use manufacturerData() which returns a multi hash.
This function was introduced in Qt 5.12.
See Also▲
See also manufacturerIds(), setManufacturerData()
[since 5.12] QMultiHash<quint16, QByteArray> QBluetoothDeviceInfo::manufacturerData() const▲
Returns the complete set of all manufacturer data from advertisement packets.
Some devices may provide multiple manufacturer data entries per manufacturer ID. An example might be a Bluetooth Low Energy device that sends a different manufacturer data via advertisement packets and scan response packets respectively. Therefore the returned hash table may have multiple entries per manufacturer ID or hash key.
This function was introduced in Qt 5.12.
See Also▲
See also setManufacturerData
[since 5.12] QList<quint16> QBluetoothDeviceInfo::manufacturerIds() const▲
Returns all manufacturer IDs from advertisement packets attached to this device information.
This function was introduced in Qt 5.12.
See Also▲
See also manufacturerData(), setManufacturerData()
quint8 QBluetoothDeviceInfo::minorDeviceClass() const▲
Returns the minor device class of the device. The actual information is context dependent on the value of majorDeviceClass().
See Also▲
QString QBluetoothDeviceInfo::name() const▲
qint16 QBluetoothDeviceInfo::rssi() const▲
QBluetoothDeviceInfo::ServiceClasses QBluetoothDeviceInfo::serviceClasses() const▲
Returns the service class of the device.
[since 6.3] QByteArray QBluetoothDeviceInfo::serviceData(const QBluetoothUuid &serviceId) const▲
Returns the data associated with the given serviceId.
Service data is defined by the Supplement to the Bluetooth Core Specification and consists of two segments:
-
Service UUID
-
Sequence of arbitrary data octets
The remote device may provide multiple data entries per serviceId. This function only returns the first entry. If all entries are needed use serviceData() which returns a multi hash.
This function was introduced in Qt 6.3.
See Also▲

[since 6.3] QMultiHash<QBluetoothUuid, QByteArray> QBluetoothDeviceInfo::serviceData() const▲
Returns the complete set of all service data from advertisement packets.
Some devices may provide multiple service data entries per service data ID. An example might be a Bluetooth Low Energy device that sends a different service data via advertisement packets and scan response packets respectively. Therefore the returned hash table may have multiple entries per service data ID or hash key.
This function was introduced in Qt 6.3.
See Also▲
See also setServiceData
[since 6.3] QList<QBluetoothUuid> QBluetoothDeviceInfo::serviceIds() const▲
Returns all service data IDs from advertisement packets attached to this device information.
This function was introduced in Qt 6.3.
See Also▲
See also serviceData(), setServiceData()
[since 6.0] QList<QBluetoothUuid> QBluetoothDeviceInfo::serviceUuids() const▲
Returns the list of service UUIDs supported by the device. Most commonly this list of UUIDs represents custom service UUIDs or a service UUID value specified by QBluetoothUuid::ServiceClassUuid.
This function was introduced in Qt 6.0.
See Also▲
See also setServiceUuids(), serviceUuids()
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▲
See also isCached()
[since 5.4] 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▲
See also coreConfigurations()
[since 5.5] void QBluetoothDeviceInfo::setDeviceUuid(const QBluetoothUuid &uuid)▲
Sets the unique identifier uuid for Bluetooth devices, that do not have addresses. This happens on macOS and iOS, where the CoreBluetooth API hides addresses, but provides UUIDs to identify devices/peripherals.
This uuid is invalid on any other platform.
This function was introduced in Qt 5.5.
See Also▲
See also deviceUuid()
[since 5.12] bool QBluetoothDeviceInfo::setManufacturerData(quint16 manufacturerId, const QByteArray &data)▲
Sets the advertised manufacturer data for the given manufacturerId. Returns true if it was inserted, false if it was already known.
Since Qt 5.14, different values for data and the same manufacturerId no longer replace each other but are accumulated for the duration of a device scan.
This function was introduced in Qt 5.12.
