LE Set Connectionless CTE Transmit Parameters.
The description below is extracted from Core_v6.0, Vol 4, Part E, Section 7.8.80
The HCI_LE_Set_Connectionless_CTE_Transmit_Parameters command is used to set the type, length, and antenna switching pattern for the transmission of Constant Tone Extensions in any periodic advertising on the advertising set identified by the Advertising_Handle parameter.
The CTE_Count parameter specifies how many packets with a Constant Tone Extension are to be transmitted in each periodic advertising event. If the number of packets that would otherwise be transmitted is less than this, the Controller shall transmit sufficient AUX_CHAIN_IND PDUs with no AdvData to make up the number. However, if a change in circumstances since this command was issued means that the Controller can no longer schedule all of these packets, it should transmit as many as possible.
If the Host issues this command when Constant Tone Extensions have been enabled in the advertising set, the Controller shall return the error code Command Disallowed (0x0C).
The Switching_Pattern_Length and Antenna_IDs[i] parameters are only used when transmitting an AoD Constant Tone Extension and shall be ignored if CTE_Type specifies an AoA Constant Tone Extension.
If the CTE_Length parameter is greater than the maximum length of Constant Tone Extension supported, the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).
If the Host requests a type of Constant Tone Extension that the Controller does not support, the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).
If the Controller is unable to schedule CTE_Count packets in each event, the Controller shall return the error code Unsupported Feature or Parameter Value (0x11). If the advertising set corresponding to the Advertising_Handle parameter does not exist, the Controller shall return the error code Unknown Advertising Identifier (0x42).
If Switching_Pattern_Length is greater than the maximum length of switching pattern supported by the Controller (see Section 7.8.87), the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).
If the Controller determines that any of the Antenna_IDs[i] values do not identify an antenna in the device's antenna array, it shall return the error code Unsupported Feature or Parameter Value (0x11).
Note: Some Controllers may be unable to determine which values do or do not identify an antenna.
Event(s) generated (unless masked away): When the HCI_LE_Set_Connectionless_CTE_Transmit_Parameters command has completed, an HCI_Command_Complete event shall be generated.
