4. Service Discovery Protocol (SDP)
4.1 Universally Unique Identifier (UUID) short forms
The Bluetooth Service Discovery Protocol (SDP) specification defines a way to represent a range of UUIDs (which are nominally 128-bits) in a shorter form. A reserved range of 232 values can be represented using 32-bits (denoted uuid32). Of these, a sub-range of 216 values can be represented using only 16 -bits (denoted uuid16). Any value in the 232 range that is not assigned in this document is reserved pending future revisions of this document. In other words, no value in this range may be used except as specified in this or future revisions of this document . UUID values outside of this range can be allocated as described in [ISO-11578] for any purpose the allocater desires.
4.2 Base Universally Unique Identifier (UUID)
The Base UUID is used for calculating 128-bit UUIDs from 'short UUIDs' (uuid16 and uuid32) as described in the SDP Specification See Service Discovery Protocol (SDP), Bluetooth SIG..

Table 4.2: Service Class Identifiers and Names
[Ref #5: If the specified Service Class directly and exactly implies a certain Profile, the Profile is indicated here (i.e. for concrete Service Classes). Leave empty for abstract Service Classes.]
The Profile column in Table 4.2 indicates which Service Class identifiers directly correspond to a Bluetooth Profile. It is not allowed to use the Service Class UUID unless the service complies with the specified Profile. These UUIDs might also appear as Profile Identifiers in the BluetoothProfileDescriptorList attribute.
