The SDP UUID lists should be searched and ALL UUIDs matched for a record to be retrieved, not partial matches. Change the SDP code so that the entire list must be matched against a service attribute table's contents before it is returned.

Browse source 
Change matching algorithm so that it recursively searches through the entire attribute table, and not just pre-specified sequence attributes.

Add browse lists and proper descriptions to the Serial Port service.
