+Start Service Discovery Command
+===============================
+
+	Command Code:		0x003a
+	Controller Index:	<controller id>
+	Command Parameters:	Address_Type (1 Octet)
+				RSSI_Threshold (1 Octet)
+				Num_UUID (1 Octet)
+				UUID[i] (16 Octets)
+	Return Parameters:	Address_Type (1 Octet)
+
+	This command is used to start the process of discovering remote
+	devices with a specific UUID. 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 service discovery uses active scanning for Low Energy scanning
+	and will search for UUID in both advertising data and scan response
+	data.
+
+	Found devices that have a RSSI value smaller than RSSI_Threshold
+	are not reported via DeviceFound event. Setting a value of 127
+	will cause all devices to be reported.
+
+	The list of UUIDs identifies a logical OR. Only one of the UUIDs
+	have to match to cause a DeviceFound event. Providing an empty
+	list of UUIDs with Num_UUID set to 0 which means that DeviceFound
+	events are send out for all devices above the RSSI_Threshold.
+
+	In case the RSSI_Threshold is set to 127 and the Num_UUID is 0,
+	then this command behaves exactly the same as Start Discovery.
+
+	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.

+Stop Service Discovery Command
+==============================
+
+	Command Code:		0x003b
+	Controller Index:	<controller id>
+	Command Parameters:	Address_Type (1 Octet)
+	Return Parameters:	Address_Type (1 Octet)
+
+	This command is used to stop the service discovery process started
+	using the Start Service Discovery command.
+
+	When the discovery procedure stops the Discovery event will
+	notify this similar to Stop Discovery.
+
+	This command can only be used when the controller is powered.
+
+	This command generates a Command Complete event on success
+	or failure.
