	  In this configuration, set BT_CTLR_SDC_CS_NUM_ANTENNAS to 1 and BT_CTLR_SDC_CS_MAX_ANTENNA_PATHS to 2
	  (since local controller can send to both of the peer antennas, creating a total of 2 antenna paths)
	  This option is purely a RAM-usage optimisation. If this option is set to 4, the controller has to reserve space for
	  a total of 5 measurements per CS-step. However, if you set this to 1, the controller will only reserve space for
	  2 measurements per CS-step.

	  Set the max number of antennas supported by local controller. This differs from BT_CTLR_SDC_CS_MAX_ANTENNA_PATHS
	  since you can run a setup where both local controller and peer controller has 2 antennas.
	  In this configuration, set BT_CTLR_SDC_CS_NUM_ANTENNAS to 2 and BT_CTLR_SDC_CS_MAX_ANTENNA_PATHS to 4
	  (since both of the local antennas can send to both of the peer's antennas, creating a total of 4 antenna paths).

	  Enable optional step mode-3 support. Channel sounding will not automatically start using step mode-3 if this
