+	Command Parameters:	Privacy (1 Octet)
+				Identity_Resolving_Key (16 Octets)
+	Return Parameters:	Current_Settings (4 Octets)
+
+	This command is used to enable Low Energy Privacy feature using

+
+	The value 0x00 disables privacy mode, the value 0x01 enables
+	privacy mode.
+
+	When the controller has a public address (mandatory for dual-mode

+	is single mode LE only without a public address, it is required
+	to configure a static random andress first. The privacy mode can
