__init__()

Constructs an invalid QBluetoothDeviceInfo object.

__init__(other)

Parameters:

other – QBluetoothDeviceInfo

Constructs a QBluetoothDeviceInfo that is a copy of other.

__init__(address, name, classOfDevice)

Parameters:

• address – QBluetoothAddress

• name – str

• classOfDevice – int

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.

__init__(uuid, name, classOfDevice)

Parameters:

• uuid – QBluetoothUuid

• name – str

• classOfDevice – int

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.

address()

Return type:

QBluetoothAddress

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()

coreConfigurations()

Return type:

Combination of CoreConfiguration

Returns the configuration of the device. If device configuration is not set, basic rate device configuration will be returned.

See also

setCoreConfigurations()

deviceUuid()

Return type:

QBluetoothUuid

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.

See also

setDeviceUuid()

isCached()

Return type:

bool

Returns true if the QBluetoothDeviceInfo object is created from cached data.

isValid()

Return type:

bool

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

majorDeviceClass()

Return type:

MajorDeviceClass

Returns the major device class of the device.

manufacturerData()

Return type:

.QMultiHashquint16,QByteArray

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.

See also

setManufacturerData

manufacturerData(manufacturerId)

Parameters:

manufacturerId – int

Return type:

QByteArray

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.

See also

manufacturerIds() setManufacturerData()

manufacturerIds()

Return type:

.list of quint16

Returns all manufacturer IDs from advertisement packets attached to this device information.

See also

manufacturerData() setManufacturerData()

minorDeviceClass()

Return type:

int

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 MinorWearableClass

name()

Return type:

str

Returns the name assigned to the device.

See also

setName()

__ne__(b)

Parameters:

b – QBluetoothDeviceInfo

Return type:

bool

Returns true if the two QBluetoothDeviceInfo objects a and b are not equal.

__eq__(b)

Parameters:

b – QBluetoothDeviceInfo

Return type:

bool

Returns true if the two QBluetoothDeviceInfo objects a and b are equal.

rssi()

Return type:

int

Returns the signal strength when the device was last scanned

See also

setRssi()

serviceClasses()

Return type:

Combination of ServiceClass

Returns the service class of the device.

serviceData()

Return type:

.QMultiHashQBluetoothUuid,QByteArray

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.

See also

setServiceData

serviceData(serviceId)

Parameters:

serviceId – QBluetoothUuid

Return type:

QByteArray

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

Note

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.

See also

serviceIds() setServiceData()

serviceIds()

Return type:

.list of QBluetoothUuid

Returns all service data IDs from advertisement packets attached to this device information.

See also

serviceData() setServiceData()

serviceUuids()

Return type:

.list of QBluetoothUuid

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 ServiceClassUuid .

See also

setServiceUuids() serviceUuids()

setCached(cached)

Parameters:

cached – bool

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()

setCoreConfigurations(coreConfigs)

Parameters:

coreConfigs – Combination of CoreConfiguration

Sets the CoreConfigurations of the device to coreConfigs. This will help to make a difference between regular and Low Energy devices.

See also

coreConfigurations()

setDeviceUuid(uuid)

Parameters:

uuid – QBluetoothUuid

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.

See also

deviceUuid()

setManufacturerData(manufacturerId, data)

Parameters:

• manufacturerId – int

• data – QByteArray

Return type:

bool

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.

See also

manufacturerData

setName(name)

Parameters:

name – str

Sets the name of the device.

See also

name()

setRssi(signal)

Parameters:

signal – int

Set the signal strength value, used internally.

setServiceData(serviceId, data)

Parameters:

• serviceId – QBluetoothUuid

• data – QByteArray
