Bluetooth LE Service UUID och karakteristiskt UUID-format 2021

A 16-bit Universally Unique Identifier (UUID) may be allocated by the SIG for use with a custom GATT-based service defined by the member. UUIDs are used in Bluetooth® protocols and applications. The SIG provides UUIDs for all the types, services, and profiles it defines. A fee of 2500 USD will be charged for each UUID. In Bluetooth, attributes types, GATT service types, characteristic types and descriptor types, and other constants are identified through UUIDs. UUIDs are no more than identifiers, 128-bit identifiers.

Predefined GATT Service UUIDs Some of the 16 bit identifiers are used to define well-known services. GATT Services are collections of characteristics and relationships to other services that encapsulate the behaviour of part of a device. A list can be found here https://www.bluetooth.com/specifications/gatt/services/. For any custom services and characteristics within the GATT, we can use an online tool to generate UUIDs such as the Online GUID Generator. A common practice is to choose a base UUID for the custom service and then increment the 3rd and 4th Most Significant Bytes (MSB) within the UUID of each included characteristic. The 0x16, 0x21 and 0x21 byte values you see in advertisements are advertising "AD" types that indicate the following bytes include the GATT Service UUID of the specified length for the type, followed by service data.
