The building blocks of all Bluetooth devices

Bluetooth® specifications define the technology building blocks that developers use to create the interoperable devices that make up the thriving Bluetooth ecosystem. Bluetooth specifications are overseen by the Bluetooth Special Interest Group (SIG) and are regularly updated and enhanced by Bluetooth SIG Working Groups to meet evolving technology and market needs.

Working Groups

Shape the future of Bluetooth as a member of a working group or committee.

Core Specifications

Get links to the most current, adopted Bluetooth Core Specifications.

Mesh Networking Specifications

Gets links to the recently adopted Mesh networking specifications (Mesh Profile, Mesh Model, and Mesh Device Properties), which define requirements to enable an interoperable many-to-many (m:m) mesh networking solution for Bluetooth Low Energy (LE) wireless technology.

Traditional Profile Specifications

Get links to the most current, adopted traditional profile specifications, which define possible applications and specify general behaviors that Bluetooth enabled devices use to communication with each other.

Protocol Specifications

Get links to the most current, adopted protocol specifications, which define the protocols that govern communication among devices on Bluetooth wireless networks.

GATT Specifications

Get links to the most current, adopted Generic Attributes (GATT) profile specifications and service specifications.

Errata Service Releases

Link to Errata Service Releases (ESRs), documents that list errata identifying corrections to each Bluetooth specification since the specification was last adopted.

Qualification Test Requirements
