Detailed Description

Advertiser.

This is the base class of legacy, extended, and periodic advertisings for common functionalities including advertising set management, TX power setting, advertising address, and so on.

On an advertising set, either the legacy or extended advertising can be enabled at a time but they cannot be enabled simultaneously on the same advertising set. For example, the following sequence shows how to start the legacy advertising on an advertising set. Starting the extended advertising is similar. The only difference is to use the extended_advertiser API class.

Create an advertise set with the sl_bt_advertiser_create_set command.
Configure and set advertising parameters for the advertising set as needed.
Set the advertising data with the sl_bt_legacy_advertiser_set_data or sl_bt_legacy_advertiser_generate_data command.
Start the legacy advertising with the sl_bt_legacy_advertiser_start command.

Periodic advertising can be enabled independently on the advertising set regardless of the state of the legacy or extended advertising. However, to ensure that scanners can find the periodic advertising information and establish a synchronization, the extended advertising must be enabled simultaneously with the periodic advertising.

When the legacy_advertiser or extended_advertiser API class is included by the application, some commands in this class are not supported. Calling them will receive SL_STATUS_NOT_SUPPORTED error code. These commands are as follows: sl_bt_advertiser_set_phy, sl_bt_advertiser_set_configuration, sl_bt_advertiser_clear_configuration, sl_bt_advertiser_set_data, sl_bt_advertiser_set_long_data, sl_bt_advertiser_start, sl_bt_advertiser_start_periodic_advertising, and sl_bt_advertiser_stop_periodic_advertising. See the command descriptions for the replacements.

◆ sl_bt_advertiser_set_random_address()

sl_status_t sl_bt_advertiser_set_random_address	(	uint8_t	`advertising_set,`
		uint8_t	`addr_type,`
		bd_addr	`address,`
		bd_addr *	`address_out`
	)

Set the advertiser on an advertising set to use a random address. This overrides the default advertiser address which is either the public device address programmed at production or the address written into persistent storage using sl_bt_system_set_identity_address command. This setting is stored in RAM only and does not change the identity address in persistent storage. In privacy mode, the stack does not change an advertiser address set by this command. To ensure that the stack can manage the address update periodically in privacy mode, the address setting should be removed with the sl_bt_advertiser_clear_random_address command.

When setting a resolvable random address, the address parameter is ignored. The stack generates one and set it as the advertiser address. The generated address is returned in the response. To enhance the privacy, the application should schedule periodic address updates by calling this command periodically. Use different schedules for different advertising sets.

To use the default advertiser address, remove this setting using sl_bt_advertiser_clear_random_address command.

Wrong state error is returned if advertising has been enabled on the advertising set. Invalid parameter error is returned if the advertising set handle is invalid or the address does not conform to the Bluetooth specification.

Parameters

[in]	`advertising_set`	Advertising set handle
[in]	`addr_type`	Address type: 1: Static device address 2: Resolvable private random address 3: Non-resolvable private random address. This type can only be used for non-connectable advertising.
[in]	`address`	The random address to set. Ignore this field when setting a resolvable random address.
[out]	`address_out`	The resolvable random address set for the advertiser. Ignore this field when setting other types of random addresses.

Returns: SL_STATUS_OK if successful. Error code otherwise.

◆ sl_bt_advertiser_clear_random_address()

sl_status_t sl_bt_advertiser_clear_random_address ( uint8_t advertising_set )

Clear the random address previously set for the advertiser address on an advertising set. To set a random address, use sl_bt_advertiser_set_random_address command. The default advertiser address will be used after this operation.

The error SL_STATUS_INVALID_STATE is returned if advertising has been enabled on the advertising set. An invalid parameter error is returned if the advertising set handle is invalid.

Parameters

[in] advertising_set Advertising set handle

Returns: SL_STATUS_OK if successful. Error code otherwise.

◆ sl_bt_advertiser_stop()

sl_status_t sl_bt_advertiser_stop ( uint8_t advertising_set )

Stop the legacy or extended advertising on an advertising set. Counterpart with sl_bt_legacy_advertiser_start or sl_bt_extended_advertiser_start.

2 (Bit 1): Omit advertiser's address from all PDUs (anonymous advertising). This flag is effective only in extended advertising.
4 (Bit 2): Use a non-resolvable private address. When this configuration is enabled, the advertising must use non-connectable mode. The stack generates a non-resolvable private address for the advertising set and the stack will update the address periodically when the privacy mode is enabled. This configuration is ignored if the advertiser address has been set with the sl_bt_advertiser_set_random_address command.
8 (Bit 3): Include TX power in advertising packets. This flag is effective only in extended advertising.
16 (Bit 4): Use the device identity address when the privacy mode is enabled in the stack. This configuration is ignored if the configuration of using non-resolvable private address is enabled or the advertising address has been set with the sl_bt_advertiser_set_random_address command.

	)

Deprecated and replaced by sl_bt_extended_advertiser_set_long_data for extended advertising PDUs and sl_bt_periodic_advertiser_set_long_data for periodic advertising PDUs.

Set advertising data for a specified packet type and advertising set. Data currently in the system data buffer will be extracted as the advertising data. The buffer will be emptied after this command regardless of the completion status.

Prior to calling this command, add data to the buffer with one or multiple calls to sl_bt_system_data_buffer_write.

Maximum 31 bytes of data can be set for legacy advertising. Maximum 191 bytes of data can be set for connectable extended advertising. Maximum 1650 bytes of data can be set for periodic and non-connectable extended advertising, but advertising parameters may limit the amount of data that can be sent in a single advertisement.

See sl_bt_advertiser_set_data for more details on advertising data.

Parameters

[in]	`advertising_set`	Advertising set handle
[in]	`packet_type`	This value selects whether data is intended for advertising packets, scan response packets, or periodic advertising packets. Values: 0: Advertising packets 1: Scan response packets 8: Periodic advertising packets

Returns: SL_STATUS_OK if successful. Error code otherwise.

◆ sl_bt_advertiser_start()

sl_status_t sl_bt_advertiser_start	(	uint8_t	`advertising_set,`
		uint8_t	`discover,`
		uint8_t	`connect`
	)

Deprecated and replaced by sl_bt_legacy_advertiser_start and sl_bt_extended_advertiser_start commands.

Start the legacy or extended advertising on an advertising set with specified discovery and connection modes.

The number of concurrent connectable advertisings is limited by the number of connections reserved by the user application (the SL_BT_CONFIG_MAX_CONNECTIONS configuration) and the number reserved by other software components (the SL_BT_COMPONENT_CONNECTIONS configuration). This command fails with the connection limit exceeded error if it may cause the number of connections exceeding the configured value in future. For example, only one connectable advertising can be enabled if the device has (SL_BT_CONFIG_MAX_CONNECTIONS + SL_BT_COMPONENT_CONNECTIONS - 1) connections. This limitation does not apply to non-connectable advertising.

The default advertising configuration in the stack is set to using legacy advertising PDUs on 1M PHY. The stack will automatically select extended advertising PDUs if either of the following has occurred with the default configuration:

The connection mode is set to sl_bt_advertiser_connectable_non_scannable.
The primary advertising PHY is set to Coded PHY by sl_bt_advertiser_set_phy.
The user advertising data length is more than 31 bytes.
Periodic advertising is enabled.

This command fails with the invalid parameter error if one of the following cases occurs:

Non-resolvable random address is used but the connection mode is advertiser_connectable_scannable or advertiser_connectable_non_scannable.
advertiser_connectable_non_scannable is the connection mode but using legacy advertising PDUs has been explicitly enabled with command sl_bt_advertiser_set_configuration.
Coded PHY is the primary advertising PHY but using legacy advertising PDUs has been explicitly enabled with command sl_bt_advertiser_set_configuration.
advertiser_connectable_scannable is the connection mode but using extended advertising PDUs has been explicitly enabled or the primary advertising PHY is set to Coded PHY.

If advertising is enabled in user_data mode, use sl_bt_advertiser_set_data to set advertising and scan response data before issuing this command. When advertising is enabled in modes other than user_data, advertising and scan response data is generated by the stack using the following procedure:

Add a flags field to advertising data.
Add a TX power level field to advertising data if the TX power service exists in the local GATT database.
Add a peripheral connection interval range field to advertising data if the GAP peripheral preferred connection parameters characteristic exists in the local GATT database.
Add a list of 16-bit service UUIDs to advertising data if there are one or more 16-bit service UUIDs to advertise. The list is complete if all advertised 16-bit UUIDs are in advertising data. Otherwise, the list is incomplete.
Add a list of 128-bit service UUIDs to advertising data if there are one or more 128-bit service UUIDs to advertise and there is still free space for this field. The list is complete if all advertised 128-bit UUIDs are in advertising data. Otherwise, the list is incomplete. Note that an advertising data packet can contain at most one 128-bit service UUID.
Try to add the full local name to advertising data if the device is not in privacy mode. If the full local name does not fit into the remaining free space, the advertised name is a shortened version by cutting off the end if the free space has at least 6 bytes. Otherwise, the local name is added to scan response data.

Event sl_bt_evt_connection_opened will be received when a remote device opens a connection to the advertiser on this advertising set. As a result, the advertising stops.

Event sl_bt_evt_advertiser_timeout will be received when the number of advertising events set by sl_bt_advertiser_set_timing command is done and the advertising has stopped.

Parameters

This mode can only be used in legacy advertising PDUs. sl_bt_advertiser_scannable_non_connectable (0x3): Undirected scannable (Non-connectable but responds to scan requests) sl_bt_advertiser_connectable_non_scannable (0x4): Undirected connectable non-scannable. This mode can only be used in extended advertising PDUs.

Returns: SL_STATUS_OK if successful. Error code otherwise.

Events

sl_bt_evt_advertiser_timeout - Triggered when the number of advertising events set by sl_bt_advertiser_set_timing command is done and advertising has stopped on an advertising set.
sl_bt_evt_connection_opened - Triggered when a remote device opens a connection to the advertiser and the advertising has stopped.

	)

Deprecated and replaced by sl_bt_periodic_advertiser_start command.

Start periodic advertising on an advertising set. The stack enables the advertising set automatically if the set was not enabled and the set can advertise using extended advertising PDUs beside the syncInfo, which is needed for the periodic advertising.

The invalid parameter error is returned if the application has configured legacy advertising PDUs or anonymous advertising, or the advertising set is enabled using legacy advertising PDUs.

To stop periodic advertising, use sl_bt_advertiser_stop_periodic_advertising command with the handle received in response from this command.
