Deprecated Core Specifications

When a specification reaches the end of its useful life, the Bluetooth® SIG may choose either to deprecate the specification, ending maintenance and restricting its use, or to withdraw the specification from use.

Important: The Bluetooth SIG strongly recommends that you use the most current specifications to design, create, and qualify your products.

For more information about specification deprecation and specification withdrawal, including effects on Bluetooth product qualification, refer to the Specification Management Process Document (SMPD) and the Qualification Program Reference Document (PRD).
