BlueZ D-Bus LEAdvertisement API documentation

Description

Advertising packets are structured data which is broadcast on the LE Advertising channels and available for all devices in range.  Because of the limited space available in LE Advertising packets, each packet's contents must be carefully controlled.

The service daemon acts as a store for the Advertisement Data which is meant to be sent. It constructs the correct Advertisement Data from the structured data and configured the kernel to send the correct advertisement.

Interface

Specifies the Advertisement Data to be broadcast and some advertising parameters.  Properties which are not present will not be included in the data.  Required advertisement data types will always be included. All UUIDs are 128-bit versions in the API, and 16 or 32-bit versions of the same UUID will be used in the advertising data as appropriate.

Service

Object path

freely definable

Methods

void Release() [noreply]

This method gets called when the service daemon removes the Advertisement. A client can use it to do cleanup tasks. There is no need to call UnregisterAdvertisement() because when this method gets called it has already been unregistered.

Properties

string Type [readonly]

Determines the type of advertising packet requested.

Possible values:

"broadcast"

"peripheral"

array{string} ServiceUUIDs

List of UUIDs to include in the "Service UUID" field of the Advertising Data.

dict ManufacturerData

Manufacturer Data fields to include in the Advertising Data.  Keys are the Manufacturer ID to associate with the data.

array{string} SolicitUUIDs

Array of UUIDs to include in "Service Solicitation" Advertisement Data.

dict ServiceData

Service Data elements to include. The keys are the UUID to associate with the data.

dict Data [Experimental]

Advertising Data to include. Key is the advertising type and value is the data as byte array.

Note: Types already handled by other properties shall not be used.

Possible values:

<type>

<byte array>

Example:

<Transport Discovery> <Organization Flags...> 0x26                   0x01         0x01...

bool Discoverable [Experimental]

Advertise as general discoverable. When present this will override adapter Discoverable property.

Note: This property shall not be set when Type is set to "broadcast".

uint16 DiscoverableTimeout [Experimental]

The discoverable timeout in seconds. A value of zero means that the timeout is disabled and it will stay in discoverable/limited mode forever.

Note: This property shall not be set when Type is set to "broadcast".

array{string} Includes

List of features to be included in the advertising packet.

Possible values:

See org.bluez.LEAdvertisingManager(5) SupportedIncludes property.

string LocalName

Local name to be used in the advertising report. If the string is too big to fit into the packet it will be truncated.

If this property is available 'local-name' cannot be present in the Includes.

uint16 Appearance

Appearance to be used in the advertising report.

Possible values: as found on GAP Service.

uint16_t Duration

Rotation duration of the advertisement in seconds. If there are other applications advertising no duration is set the default is 2 seconds.

uint16_t Timeout

Timeout of the advertisement in seconds. This defines the lifetime of the advertisement.

string SecondaryChannel [Experimental]

Secondary channel to be used. Primary channel is always set to "1M" except when "Coded" is set.

Possible value:

"1M" (default)

"2M"

"Coded"

uint32 MinInterval [Experimental]

Minimum advertising interval to be used by the advertising set, in milliseconds. Acceptable values are in the range [20ms, 10,485s]. If the provided MinInterval is larger than the provided MaxInterval, the registration will return failure.

uint32 MaxInterval [Experimental]

Maximum advertising interval to be used by the advertising set, in milliseconds. Acceptable values are in the range [20ms, 10,485s]. If the provided MinInterval is larger than the provided MaxInterval, the registration will return failure.

int16 TxPower [Experimental]

Requested transmission power of this advertising set. The provided value is used only if the "CanSetTxPower" feature is enabled on the org.bluez.LEAdvertisingManager(5). The provided value must be in range [-127 to +20], where units are in dBm.
