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 QLowEnergyController::startAdvertising().

Member Type Documentation▲
enum QLowEnergyAdvertisingParameters::FilterPolicy▲
Specifies the semantics of the white list.

Description |
|---|---|---|
|
QLowEnergyAdvertisingParameters::IgnoreWhiteList |
0x00 |
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 |
0x01 |
The white list is used when handling scan requests, but is ignored for connection requests. |
|
QLowEnergyAdvertisingParameters::UseWhiteListForConnecting |
0x02 |
The white list is used when handling connection requests, but is ignored for scan requests. |
|
QLowEnergyAdvertisingParameters::UseWhiteListForScanningAndConnecting |
0x03 |
The white list is used for both connection and scan requests. |

enum QLowEnergyAdvertisingParameters::Mode▲
Specifies in which way to advertise.

Description |

|
QLowEnergyAdvertisingParameters::AdvInd |
0x0 |
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 |
0x2 |
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 |
0x3 |
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. |
Member Function Documentation▲
QLowEnergyAdvertisingParameters::QLowEnergyAdvertisingParameters()▲
Constructs a new object of this class. All values are initialized to their defaults according to the Bluetooth Low Energy specification.
QLowEnergyAdvertisingParameters::QLowEnergyAdvertisingParameters(const QLowEnergyAdvertisingParameters &other)▲
Constructs a new object of this class that is a copy of other.
QLowEnergyAdvertisingParameters::~QLowEnergyAdvertisingParameters()▲
Destroys this object.
QLowEnergyAdvertisingParameters::FilterPolicy QLowEnergyAdvertisingParameters::filterPolicy() const▲
Returns the filter policy that determines how the white list is used. The default is QLowEnergyAdvertisingParameters::IgnoreWhiteList.
int QLowEnergyAdvertisingParameters::maximumInterval() const▲
Returns the maximum advertising interval in milliseconds. The default is 1280.
int QLowEnergyAdvertisingParameters::minimumInterval() const▲
Returns the minimum advertising interval in milliseconds. The default is 1280.
QLowEnergyAdvertisingParameters::Mode QLowEnergyAdvertisingParameters::mode() const▲
Returns the advertising mode. The default is QLowEnergyAdvertisingParameters::AdvInd.
See Also▲
See also setMode()
void QLowEnergyAdvertisingParameters::setInterval(quint16 minimum, quint16 maximum)▲
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.
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.
void QLowEnergyAdvertisingParameters::setMode(QLowEnergyAdvertisingParameters::Mode mode)▲
void QLowEnergyAdvertisingParameters::setWhiteList(const QList<QLowEnergyAdvertisingParameters::AddressInfo> &whiteList, QLowEnergyAdvertisingParameters::FilterPolicy policy)▲
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.

See also whiteList()
void QLowEnergyAdvertisingParameters::swap(QLowEnergyAdvertisingParameters &other)▲
Swaps this object with other.
QList<QLowEnergyAdvertisingParameters::AddressInfo> QLowEnergyAdvertisingParameters::whiteList() const▲
Returns the white list used for filtering scan and connection requests. By default, this list is empty.

QLowEnergyAdvertisingParameters &QLowEnergyAdvertisingParameters::operator=(const QLowEnergyAdvertisingParameters &other)▲
Makes this object a copy of other and returns the new value of this object.

bool operator==(const QLowEnergyAdvertisingParameters &a, const QLowEnergyAdvertisingParameters &b)▲
Returns true if a and b are equal with respect to their public state, otherwise returns false.
