@@ -11,37 +11,128 @@ LE Channel Sounding (CS) is a feature defined in the `Bluetooth Core Specificati
 CS allows two devices in a connection to perform measurements of their communication channel, both the round trip time (RTT), and the phase and magnitude (as in-phase and quadrature (IQ) values) can be measured.
 The RTT and IQ values can then be sent to an application to calculate the distance between devices.
 
+Support status
+**************
+
 Channel Sounding currently has :ref:`Experimental <nrf:software_maturity>` support in the |controller| for the nRF54L15 SoC.
 CS can be enabled by building with the :kconfig:option:`CONFIG_BT_CTLR_CHANNEL_SOUNDING` Kconfig option enabled.
 
-Developing with CS
-******************
-
-Currently, the :zephyr:code-sample:`bluetooth_hci_uart` sample is recommended to get started with Channel Sounding.
-Build the sample with the following command to enable the CS feature:
+Command support
+---------------
 
-.. code-block:: console
-
-   west build -b nrf54l15dk/nrf54l15/cpuapp --pristine -- -DCONFIG_BT_CTLR_CHANNEL_SOUNDING=y
-
-You can use the sample to run the following supported HCI commands over UART:
+The following LE CS commands are supported:
 
  * LE CS Read Local Supported Capabilities
  * LE CS Read Remote Supported Capabilities
+ * LE CS Write Cached Remote Supported Capabilities
  * LE CS Security Enable
  * LE CS Set Default Settings
  * LE CS Read Remote FAE Table
+ * LE CS Write Cached Remote FAE Table
  * LE CS Create Config
+ * LE CS Remove Config
  * LE CS Set Channel Classification
  * LE CS Set Procedure Parameters
  * LE CS Procedure Enable
  * LE CS Test
  * LE CS Test End
 
-Experimental Limitations
-************************
+Supported capabilities
+----------------------
+
+The |controller| currently has the following supported capabilities:
+
+ * One CS Configuration per ACL connection.
+ * Indefinite Procedure Repeats.
+ * Four Antennas and Four Antenna Paths.
+ * CS Reflector and CS Initiator Roles.
+ * Step modes 1, 2, and 3.
+ * 150 ns time-of-flight precision
+ * RTT with AA-only and 32, 64, 96, and 128 bits random payloads
+ * 1M and 2M CS Sync Phy
+ * No Transmitter Frequency Actuation Error
+
+The supported timing values for the |controller| are as follows:
+
+ * A T_IP1 of 60 µs or greater.
+ * A T_IP2 of 30 µs or greater.
+ * A T_FCS of 60 µs or greater.
+ * A T_PM of 10 µs or greater.
+ * A T_SW of 10 µs.
+
+Multiple antennas support
+-------------------------
+
+Currently, the |controller| supports multiple antennas with a fixed pinout for the multi-antenna switch.
+In order to use the |controller| with multiple antennas, an external GPIO controlled multi-antenna switch needs to be set up with the following truth table:
+
+.. list-table:: Antenna control for multi-antenna switching.
+   :widths: 30 5 5 5 5
+   :header-rows: 1
+
+   * - Active Antenna:
+     - **P1.11**
+     - **P1.12**
+     - **P1.13**
+     - **P1.14**
+   * - Antenna 1
+     - 1
+     - 0
+     - 0
+     - 0
+   * - Antenna 2

+   * - Antenna 3
+     - 0

+     - 0
+   * - Antenna 4
+     - 0
+     - 0
+     - 0
+     - 1
+
+.. note::
+   Currently, the |controller| needs a maximum of 4 µs to trigger an antenna switch within the T_SW period.
+   This means that any multi-antenna switch with the correct pinout must switch within 6 µs to maintain 10 µs T_SW.
+
+Experimental limitations
+------------------------
 
 Currently, the following limitations apply to the :ref:`Experimental <nrf:software_maturity>` support of Channel Sounding:
 
  * :ref:`radio coexistence <nrf:ug_radio_coex>` and :ref:`front-end modules <mpsl_fem>` are not supported.
  * Only one subevent per event is supported in CS.
+
+Developing with CS
+******************
+
+The following samples are recommended for getting started with Channel Sounding:
+
+1. Using the Ranging Service samples:
+
+   * :ref:`Bluetooth: Channel Sounding Initiator with Ranging Requestor <nrf:channel_sounding_ras_initiator>`.
+   * :ref:`Bluetooth: Channel Sounding Reflector with Ranging Responder <nrf:channel_sounding_ras_reflector>`.
+
+2. Using the :zephyr:code-sample:`bluetooth_hci_uart` sample and running HCI commands over UART.
+
+.. note::
+   To build the :zephyr:code-sample:`bluetooth_hci_uart` sample with Channel Sounding enabled, set :kconfig:option:`CONFIG_BT_CTLR_CHANNEL_SOUNDING` to ``y``.
+
+   .. code-block:: console
+
+      west build -b nrf54l15dk/nrf54l15/cpuapp --pristine -- -DCONFIG_BT_CTLR_CHANNEL_SOUNDING=y
+
+Optional CS Kconfigs
+--------------------
+
+Use the following Kconfig options to enable the desired optional CS features:
+
+ * Set :kconfig:option:`BT_CTLR_SDC_CS_STEP_MODE3` to ``y`` to enable Channel Sounding step mode-3 support.
+
+ * Set :kconfig:option:`BT_CTLR_SDC_CS_MAX_ANTENNA_PATHS` to a value between ``2`` and ``4`` to enable Channel Sounding multiple antenna paths support.
+ * Set :kconfig:option:`BT_CTLR_SDC_CS_NUM_ANTENNAS` to a value between ``2`` and :kconfig:option:`BT_CTLR_SDC_CS_MAX_ANTENNA_PATHS` to enable Channel Sounding multiple antennas support.
