## Member Function Documentation

### QBluetoothDeviceInfo::QBluetoothDeviceInfo(const QBluetoothDeviceInfo &other)

Constructs a QBluetoothDeviceInfo that is a copy of other.

### 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 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()

Constructs an invalid QBluetoothDeviceInfo object.

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

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

### QBluetoothDeviceInfo::~QBluetoothDeviceInfo()

Destroys the QBluetoothDeviceInfo.

### QBluetoothAddress QBluetoothDeviceInfo::address() const

Returns the address of the device.

Note: 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 deviceUuid().

### 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().

### 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 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.

### MajorDeviceClass QBluetoothDeviceInfo::majorDeviceClass() const

Returns the major device class of the device.

### 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.

Note: 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 manufacturerIds() and setManufacturerData().

### QHash<quint16, QByteArray> QBluetoothDeviceInfo::manufacturerData() const

Returns the complete set of all manufacturer data.

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 setManufacturerData.

### QVector<quint16> QBluetoothDeviceInfo::manufacturerIds() const

Returns all manufacturer ids attached to this device information.

This function was introduced in Qt 5.12.

See also manufacturerData() and 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 MinorAudioVideoClass, MinorComputerClass, MinorHealthClass, MinorImagingClass, MinorMiscellaneousClass, MinorNetworkClass, MinorPeripheralClass, MinorPhoneClass, MinorToyClass, and MinorWearableClass.

### 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 = nullptr) 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().

### 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::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 deviceUuid().

### 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.

See also manufacturerData.

### void QBluetoothDeviceInfo::setRssi(qint16 signal)

Set the signal strength value, used internally.

See also rssi().

### void QBluetoothDeviceInfo::setServiceUuids(const QVector<QBluetoothUuid> &uuids)

Sets the list of service UUIDs to uuids.

This function was introduced in Qt 5.13.

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

Returns true if this object is different from other, or false otherwise.

See also operator==().

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

Returns true if the other QBluetoothDeviceInfo object and this are identical.
