LE Set Extended Scan Parameters.
The description below is extracted from Core_v6.0, Vol 4, Part E, Section 7.8.64
The HCI_LE_Set_Extended_Scan_Parameters command is used to set the extended scan parameters to be used on the advertising physical channels.
The Scanning_PHYs parameter indicates the PHY(s) on which the advertising packets should be received on the primary advertising physical channel. The Host may enable one or more scanning PHYs. If the Host specifies a PHY that is not supported by the Controller, including a bit that is reserved for future use, it should return the error code Unsupported Feature or Parameter Value (0x11). The Scan_Type[i], Scan_Interval[i], and Scan_Window[i] parameters array elements are ordered in the same order as the set bits in the Scanning_PHY parameter, starting from bit 0. The number of array elements is determined by the number of bits set in the Scanning_PHY parameter.
The Scan_Type[i] parameter specifies the type of scan to perform.
The Scan_Interval[i] and Scan_Window[i] parameters are recommendations from the Host on how long (Scan_Window[i]) and how frequently (Scan_Interval[i]) the Controller should scan (see [Vol 6] Part B, Section 4.4.3); however the frequency and length of the scan is implementation specific. If the requested scan cannot be supported by the implementation, the Controller shall return the error code Invalid HCI Command Parameters (0x12).
The Own_Address_Type parameter indicates the type of address being used in the scan request packets.
If the Host issues this command when scanning is enabled in the Controller, the Controller shall return the error code Command Disallowed (0x0C).
If the Controller does not support the Decision-Based Advertising Filtering feature and the Host issues this command with bits 2 and 3 of Scanning_Filter_Policy set to a value other than 0b00, the Controller shall return an error code which should be Unsupported Feature or Parameter Value (0x11).
Event(s) generated (unless masked away): When the HCI_LE_Set_Extended_Scan_Parameters command has completed, an HCI_Command_Complete event shall be generated.
