themselves as Channel Sounding distance providers via
RegisterDistanceProvider/UnregisterDistanceProvider.

+org.bluez.CSDistanceProviderManager
+====================================
+
+--------------------------------------------------------
+BlueZ D-Bus CSDistanceProviderManager API documentation
+--------------------------------------------------------
+
+:Version: BlueZ
+:Date: July 2026
+:Manual section: 5
+:Manual group: Linux System Administration
+
+Description
+===========
+
+A Channel Sounding distance provider starts by registering itself as a
+distance provider with the **RegisterDistanceProvider()** method passing
+an object path as the provider ID. Then, it can start exposing
+**org.bluez.CSDistanceProvider(5)** objects having the path
+starting with the given provider ID. It can also remove objects at any
+time.
+The objects and their properties exposed by distance providers will be
+reflected on the matching **org.bluez.CSDistance1(5)**
+interface.
+
+**bluetoothd(8)** will stop monitoring these exposed and removed objects
+after UnregisterDistanceProvider is called for that provider ID.
+
+Interface
+=========
+
+:Service:	org.bluez
+:Interface:	org.bluez.CSDistanceProviderManager1
+:Object path:	/org/bluez/{hci0,hci1,...}
+
+Methods
+-------
+
+void RegisterDistanceProvider(object provider)
+``````````````````````````````````````````````
+
+Registers a distance provider. A registered distance provider can then
+expose objects with **org.bluez.CSDistanceProvider(5)**
+interface.
+
+void UnregisterDistanceProvider(object provider)
+````````````````````````````````````````````````
+
+Unregisters a distance provider previously registered with
+**RegisterDistanceProvider()**. After unregistration, the
+**org.bluez.CSDistanceProvider(5)** objects provided by this
+client are ignored by **bluetoothd(8)**.
