+ void StartFilteredDiscovery(dict filter, string transport)
+
+ This method starts the device discovery session with
+ filtering by uuids, and rssi or pathloss value. Use
+ StopDiscovery to release the sessions acquired.
+
+ transport parameter:
+ "auto" - interleaved scan, default value
+ "bredr" - br/edr inquiry
+ "le" - le only scan
+
+ Parameters that can be set in filter dictionary include
+ the following:
+
+ array{string} UUIDs : filtered service UUIDs (required)
+ int16 RSSI : RSSI threshold value (optional)
+ uint16 pathloss : Pathloss threshold value (optional)
+
+ When a device is found that advertise any UUID from
+ UUIDs, it will be reported if:
+ - pathloss and RSSI are both empty,
+ - only pathloss param is set, device advertise TX pwer,
+ and computed pathloss is less than pathloss param,
+ - only RSSI param is set, and received RSSI is higher
+ than RSSI param,
+
+ This process will start creating Device objects as new
+ devices matching criteria are discovered. It will also
+ emit PropertiesChanged signal for already existing
+ Device objects, with updated RSSI value.
+
+ Possible errors: org.bluez.Error.NotReady
+ org.bluez.Error.Failed
