LE Set Advertising Parameters.
The description below is extracted from Core_v6.0, Vol 4, Part E, Section 7.8.5
The HCI_LE_Set_Advertising_Parameters command is used by the Host to set the advertising parameters.
The Advertising_Interval_Min shall be less than or equal to the Advertising_Interval_Max. The Advertising_Interval_Min and Advertising_Interval_Max should not be the same value to enable the Controller to determine the best advertising interval given other activities.
For high duty cycle directed advertising, i.e. when Advertising_Type is 0x01 (ADV_DIRECT_IND, high duty cycle), the Advertising_Interval_Min and Advertising_Interval_Max parameters are not used and shall be ignored.
The Advertising_Type is used to determine the packet type that is used for advertising when advertising is enabled.
Own_Address_Type parameter indicates the type of address being used in the advertising packets.
If Own_Address_Type equals 0x02 or 0x03, the Peer_Address parameter contains the peer’s Identity Address and the Peer_Address_Type parameter contains the Peer’s Identity Type (i.e. 0x00 or 0x01). These parameters are used to locate the corresponding local IRK in the resolving list; this IRK is used to generate the own address used in the advertisement.
If directed advertising is performed, i.e. when Advertising_Type is set to 0x01 (ADV_DIRECT_IND, high duty cycle) or 0x04 (ADV_DIRECT_IND, low duty cycle mode), then the Peer_Address_Type and Peer_Address shall be valid.
If Own_Address_Type equals 0x02 or 0x03, the Controller generates the peer’s Resolvable Private Address using the peer’s IRK corresponding to the peer’s Identity Address contained in the Peer_Address parameter and peer’s Identity Address Type (i.e. 0x00 or 0x01) contained in the Peer_Address_Type parameter.
The Advertising_Channel_Map is a bit field that indicates the advertising channel indices that shall be used when transmitting advertising packets. At least one channel bit shall be set in the Advertising_Channel_Map parameter.
The Advertising_Filter_Policy parameter shall be ignored when directed advertising is enabled.
The Host shall not issue this command when advertising is enabled in the Controller; if it is the Command Disallowed error code shall be used.
If the advertising interval range provided by the Host (Advertising_Interval_Min, Advertising_Interval_Max) does not overlap with the advertising interval range supported by the Controller, then the Controller shall return the Unsupported Feature or Parameter Value (0x11) error code.
Event(s) generated (unless masked away): When the HCI_LE_Set_Advertising_Parameters command has completed, an HCI_Command_Complete event shall be generated.
