Service Discovery Protocol (SDP)

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).

All values in the 232 range that are not assigned in this document are 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 allocator desires.

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) in the Bluetooth Core Specification.

NOTE: Currently all assigned short UUIDs are uuid16 types.

Table 1: Protocol Identifiers and Names, Service Classes and Profile Identifiers

UUIDs in the following table, which have an allowed usage of Service Class may be used in the ServiceClassIDList universal attribute, but shall not be used in the BluetoothProfileDescriptorList attribute unless the Profile usage is also allowed per the table below. If a Service Class UUID is exposed in the SDP database of a product, then the product containing the SDP record shall comply with the specification that defines the service corresponding to the UUID.

UUIDs in the following table which have an allowed usage of Profile may be used in the BluetoothProfileDescriptorList universal attribute, but shall not be used in the ServiceClassIDList universal attribute unless the Service Class usage is also allowed per the table below.

For historical reasons, some UUIDs in Table 2 are used to identify profiles in a BluetoothProfileDescriptorList universal attribute as well as service classes in a ServiceClassIDList universal attribute. However, for new profiles, Service Class UUIDs shall not be used in a BluetoothProfileDescriptorList universal attribute and Profile UUIDs shall not be used in a ServiceClassIDList universal attribute.
