+Start Limited Discovery Command
+===============================
+
+ Command Code: 0x0040
+ Controller Index: <controller id>
+ Command Parameters: Address_Type (1 Octet)
+ Return Parameters: Address_Type (1 Octet)
+
+ This command is used to start the process of discovering remote
+ devices using the limited discovery procedure. A Device Found event
+ will be sent for each discovered device.
+
+ Possible values for the Address_Type parameter are a bit-wise or
+ of the following bits:
+
+ 0 BR/EDR
+ 1 LE Public
+ 2 LE Random
+
+ By combining these e.g. the following values are possible:
+
+ 1 BR/EDR
+ 6 LE (public & random)
+ 7 BR/EDR/LE (interleaved discovery)
+
+ The limited discovery uses active scanning for Low Energy scanning
+ and will search for devices with the limited discoverabilty flag
+ configured. On BR/EDR it uses LIAC and filters on the limited
+ discoverabilty flag of the class of device.
+
+ When the discovery procedure starts the Discovery event will
+ notify this similar to Start Discovery.
+
+ This command can only be used when the controller is powered.
+
+ This command generates a Command Complete event on success
+ or failure.
+
+ Possible errors: Busy
+ Not Supported
+ Invalid Parameters
+ Not Powered
