At the core of everything Bluetooth
The Bluetooth® Core Specification defines the technology building blocks that developers use to create the interoperable devices that make up the thriving Bluetooth ecosystem. The Bluetooth specification is overseen by the Bluetooth Special Interest Group (SIG) and is regularly updated and enhanced by Bluetooth SIG Working Groups to meet evolving technology and market needs.
The documents in the “Informative document showing changes” column are provided as a courtesy to help readers identify changes between two versions of a Bluetooth® specification. When implementing specifications, use the adopted versions in the “Adopted Version” column.
To ensure interoperability of devices, members are encouraged to implement adopted errata.
