Detailed Description

Parameters defining the advertising process.

Legacy advertising:

Advertising parameters for legacy advertising are a mainly defined by a pair of values:

The Advertising mode modeled after advertising_type_t. It defines whether the device is connectable and scannable. You can set this value at construction time, update it with setType() and query it with getType().
Time interval between advertisement. You can set it at construction time, update it with setPrimaryInterval() and obtain it from getMinPrimaryInterval() and getMaxPrimaryInterval().

In addition, it is possible to adjust other parameters:

You can select the advertising channels with setPrimaryChannels() and queried them with getChannel37(), getChannel38() and getChannel39().
You can set the address type used by the local device with setOwnAddressType() and query it by getOwnAddressType().
You can set the filter policy for scan and connection requests with setFilter() and query it with getFilter().

For directed advertising, you can set the address of the target with the help of setPeer() and query it with getPeerAddress() and getPeerAddressType().

Extended advertising:

To use extended advertising features, first disable legacy advertising with setUseLegacyPDU().

Extended advertising adds new features to BLE advertising:

Control the advertising power with setTxPower().
Include the Tx power in advertising packet with includeTxPowerInHeader().
Set a secondary phy_t channel with setPhy().
Enable scan requests notification to let the application be aware of any incoming scan requests with setScanRequestNotification().
Advertise anonymously with setAnonymousAdvertising()

Fluent interface:

This API is designed for usability. You can construct it and pass it in place. To achieve this, the fluent interface pattern is used. Every setter returns a reference to the object modified and can be chained.

void setAdvertisingParameters(ble::PalGap& gap) {
    using namespace ble;
    gap.setAdvertisingParameters(
        LEGACY_ADVERTISING_HANDLE,
        AdvertisingParameters()
            .setType(advertising_type_t::ADV_CONNECTABLE_UNDIRECTED)
            .setPrimaryInterval(millisecond_t(200), millisecond_t(500))
            .setOwnAddressType(own_address_type_t::RANDOM)
            .setUseLegacyPDU(false)
            .setPhy(phy_t::LE_1M, phy_t::LE_CODED)

Constructor & Destructor Documentation

AdvertisingParameters	(	advertising_type_t	advType = `advertising_type_t::CONNECTABLE_UNDIRECTED`,
		adv_interval_t	minInterval = `adv_interval_t(DEFAULT_ADVERTISING_INTERVAL_MIN)`,
		adv_interval_t	maxInterval = `adv_interval_t(DEFAULT_ADVERTISING_INTERVAL_MAX)`,
		bool	useLegacyPDU = `true`
	)

Construct an instance of GapAdvertisingParams.

Parameters

[in]	advType	Type of advertising.
[in]	minInterval,maxInterval	Time interval between two advertisement. A range is provided to the LE subsystem, so it can adjust the advertising interval with other transmission happening on the BLE radio.
[in]	useLegacyPDU	If true legacy PDU shall be used for advertising.

Note: If CONNECTABLE_UNDIRECTED or CONNECTABLE_DIRECTED advertising is used you must use legacy PDU.; If values in input are out of range, they will be normalized.; If type selected is incompatible with non legacy PDU, legacy PDU will be used.

Parameters

[in]	advType	Type of advertising.
[in]	useLegacyPDU	If true legacy PDU shall be used for advertising.
