Detailed Description

This data can include the device name, GATT services offered by the device, and so on. The data set via this class will be used when advertising is started by calling startAdvertising() . Objects of this class can represent an Advertising Data packet or a Scan Response packet.

Note

The actual data packets sent over the advertising channel cannot contain more than 31 bytes. If the variable-length data set via this class exceeds that limit, it will be left out of the packet or truncated, depending on the type. On Android, advertising will fail if advertising data is larger than 31 bytes. On Bluez DBus backend the advertising length limit and the behavior when it is exceeded is up to BlueZ; it may for example support extended advertising. For the most predictable behavior keep the advertising data short.

class Discoverability

The discoverability of the advertising device as defined by the Generic Access Profile.

Constant	Description
QLowEnergyAdvertisingData.DiscoverabilityNone	The advertising device does not wish to be discoverable by scanning devices.
QLowEnergyAdvertisingData.DiscoverabilityLimited	The advertising device wishes to be discoverable with a high priority. Note that this mode is not compatible with using a white list. The value of filterPolicy() is always assumed to be IgnoreWhiteList when limited discoverability is used.
QLowEnergyAdvertisingData.DiscoverabilityGeneral	The advertising device wishes to be discoverable by scanning devices.

__init__()

Creates a new object of this class. All values are initialized to their defaults according to the Bluetooth Low Energy specification.

__init__(other)

Parameters:

other – QLowEnergyAdvertisingData

Constructs a new object of this class that is a copy of other.

discoverability()

Return type:

Discoverability

Returns the discoverability mode of the advertising device. The default is DiscoverabilityNone .

See also

setDiscoverability()

includePowerLevel()

Return type:

bool

Returns whether to include the device’s transmit power level in the advertising data. The default is false.

See also

setIncludePowerLevel()

static invalidManufacturerId()

Return type:

int

Returns an invalid manufacturer id. If this value is set as the manufacturer id (which it is by default), no manufacturer data will be present in the advertising data.

localName()

Return type:

str

Returns the name of the local device that is to be advertised.

See also

setLocalName()

manufacturerData()

Return type:

QByteArray

Returns the manufacturer data. The default is an empty byte array.

See also

setManufacturerData()

manufacturerId()

Return type:

int

Returns the manufacturer id. The default is invalidManufacturerId() , which means the data will not be advertised.

__ne__(b)

Parameters:

b – QLowEnergyAdvertisingData

Return type:

bool

Returns true if data1 and data2 are not equal with respect to their public state, otherwise returns false.

__eq__(b)

Parameters:

b – QLowEnergyAdvertisingData

Return type:

bool

Returns true if data1 and data2 are equal with respect to their public state, otherwise returns false.

rawData()

Return type:

QByteArray

Returns the user-supplied raw data to be advertised. The default is an empty byte array.

See also

setRawData()

services()

Return type:

.list of QBluetoothUuid

Returns the list of service UUIDs to be advertised. By default, this list is empty.

See also

setServices()

setDiscoverability(mode)

Parameters:

mode – Discoverability

Sets the discoverability type of the advertising device to mode.

Note

Discoverability information can only appear in an actual advertising data packet. If this object acts as scan response data, a call to this function will have no effect on the scan response sent.

discoverability()

setIncludePowerLevel(doInclude)

Parameters:

doInclude – bool

Specifies whether to include the device’s transmit power level in the advertising data. If doInclude is true, the data will be included, otherwise it will not.

See also

includePowerLevel()

setLocalName(name)

Parameters:

name – str

Specifies that name should be broadcast as the name of the device. If the full name does not fit into the advertising data packet, an abbreviated name is sent, as described by the Bluetooth Low Energy specification.

On Android, the local name cannot be changed. Android always uses the device name. If this local name is not empty, the Android implementation includes the device name in the advertisement packet; otherwise the device name is omitted from the advertisement packet.

localName()

setManufacturerData(id, data)

Parameters:

• id – int

• data – QByteArray

Sets the manufacturer id and data. The id parameter is a company identifier as assigned by the Bluetooth SIG. The data parameter is an arbitrary value.

See also

manufacturerData()

setRawData(data)

Parameters:

data – QByteArray

Sets the data to be advertised to data. If the value is not an empty byte array, it will be sent as-is as the advertising data and all other data in this object will be ignored. This can be used to send non-standard data.

Note

If data is longer than 31 bytes, it will be truncated. It is the caller’s responsibility to ensure that data is well-formed.

Providing the raw advertising data is not supported on BlueZ DBus backend as BlueZ does not support it. This may change in a future release.

rawData()

setServices(services)

Parameters:

services – .list of QBluetoothUuid

Specifies that the service UUIDs in services should be advertised. If the entire list does not fit into the packet, an incomplete list is sent as specified by the Bluetooth Low Energy specification.

services()

swap(other)

Parameters:

other – QLowEnergyAdvertisingData

Swaps this object with other.
