Detailed Description¶

When running the advertising procedure, a number of parameters can be configured, such as how fast to advertise or which clients, if any, can connect to the advertising device. These parameters are set via this class, and their values will be used when advertising is started by calling startAdvertising() .

QLowEnergyAdvertisingData startAdvertising()

class Mode¶

Specifies in which way to advertise.

Constant

Description

QLowEnergyAdvertisingParameters.AdvInd

For non-directed, connectable advertising. Advertising is not directed to one specific device and a device seeing the advertisement can connect to the advertising device or send scan requests.

QLowEnergyAdvertisingParameters.AdvScanInd

For non-directed, scannable advertising. Advertising is not directed to one specific device and a device seeing the advertisement can send a scan request to the advertising device, but cannot connect to it.

QLowEnergyAdvertisingParameters.AdvNonConnInd

For non-directed, non-connectable advertising. Advertising is not directed to one specific device. A device seeing the advertisement cannot connect to the advertising device, nor can it send a scan request. This mode thus implies pure broadcasting.

Constant	Description
QLowEnergyAdvertisingParameters.AdvInd	For non-directed, connectable advertising. Advertising is not directed to one specific device and a device seeing the advertisement can connect to the advertising device or send scan requests.
QLowEnergyAdvertisingParameters.AdvScanInd	For non-directed, scannable advertising. Advertising is not directed to one specific device and a device seeing the advertisement can send a scan request to the advertising device, but cannot connect to it.
QLowEnergyAdvertisingParameters.AdvNonConnInd	For non-directed, non-connectable advertising. Advertising is not directed to one specific device. A device seeing the advertisement cannot connect to the advertising device, nor can it send a scan request. This mode thus implies pure broadcasting.

class FilterPolicy¶

Specifies the semantics of the white list.

Constant

Description

QLowEnergyAdvertisingParameters.IgnoreWhiteList

The value of the white list is ignored, that is, no filtering takes place for either scan or connection requests when using undirected advertising.

QLowEnergyAdvertisingParameters.UseWhiteListForScanning

The white list is used when handling scan requests, but is ignored for connection requests.

QLowEnergyAdvertisingParameters.UseWhiteListForConnecting

The white list is used when handling connection requests, but is ignored for scan requests.

QLowEnergyAdvertisingParameters.UseWhiteListForScanningAndConnecting

The white list is used for both connection and scan requests.

whiteList()

Constant	Description
QLowEnergyAdvertisingParameters.IgnoreWhiteList	The value of the white list is ignored, that is, no filtering takes place for either scan or connection requests when using undirected advertising.
QLowEnergyAdvertisingParameters.UseWhiteListForScanning	The white list is used when handling scan requests, but is ignored for connection requests.
QLowEnergyAdvertisingParameters.UseWhiteListForConnecting	The white list is used when handling connection requests, but is ignored for scan requests.
QLowEnergyAdvertisingParameters.UseWhiteListForScanningAndConnecting	The white list is used for both connection and scan requests.

__init__()¶

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

__init__(other)

Parameters:: other – QLowEnergyAdvertisingParameters

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

filterPolicy()¶

Return type:: FilterPolicy

Returns the filter policy that determines how the white list is used. The default is IgnoreWhiteList .

maximumInterval()¶

Return type:: int

Returns the maximum advertising interval in milliseconds. The default is 1280.

minimumInterval()¶

Return type:: int

Returns the minimum advertising interval in milliseconds. The default is 1280.

mode()¶

Return type:: Mode

Returns the advertising mode. The default is AdvInd .

setMode()

__ne__(b)¶

Parameters:: b – QLowEnergyAdvertisingParameters
Return type:: bool

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

__eq__(b)¶

Parameters:: b – QLowEnergyAdvertisingParameters
Return type:: bool

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

setInterval(minimum, maximum)¶

Parameters:

minimum – int
maximum – int

Sets the advertising interval. This is a range that gives the controller an upper and a lower bound for how often to send the advertising data. Both minimum and maximum are given in milliseconds. If maximum is smaller than minimum, it will be set to the value of minimum.

Note

There are limits for the minimum and maximum interval; the exact values depend on the mode. If they are exceeded, the lowest or highest possible value will be used, respectively.

Setting the advertising interval is supported on BlueZ DBus backend if its experimental status is changed in later versions of BlueZ (or run in experimental mode).

setMode(mode)¶

Parameters:: mode – Mode

Sets the advertising mode to mode.

See also

mode()

setWhiteList(whiteList, policy)¶

Parameters:

whiteList – .list of QLowEnergyAdvertisingParameters.AddressInfo
policy – FilterPolicy

Sets the white list that is potentially used for filtering scan and connection requests. The whiteList parameter is the list of addresses to use for filtering, and policy specifies how exactly to use whiteList.

Whitelists are not supported on the BlueZ DBus backend as they are not supported by BlueZ.

See also

whiteList()

swap(other)¶

Parameters:: other – QLowEnergyAdvertisingParameters

Swaps this object with other.

whiteList()¶

Return type:: .list of QLowEnergyAdvertisingParameters.AddressInfo

Returns the white list used for filtering scan and connection requests. By default, this list is empty.
