Communicating supported Bluetooth® functionality

1. Introduction

After successfully completing the Bluetooth® Qualification Process for a product, Bluetooth SIG members are encouraged to communicate the supported Bluetooth functionality in their product packaging and promotional materials, such as product data sheets and web pages. This guide provides recommendations for effectively communicating support for essential aspects of Bluetooth technology.

The guide aims to achieve three goals:

  • Encourage consistent public communication of supported Bluetooth functionality
  • Help customers easily identify Bluetooth technology and capabilities in products
  • Increase customer confidence that products are up to date with the latest Bluetooth technology

It offers a framework that defines Bluetooth communication elements, preferred terminology, and usage criteria established by the Bluetooth SIG for each element. The intended audiences include members developing end-use products (e.g., mice, headphones, electronic shelf labels) and enabling technology products (e.g., chipsets, stacks, modules). The Bluetooth SIG advises members to refer to this guidance when publicly communicating supported Bluetooth functionality.

2. End-Use product guidance

This section provides guidance on communicating supported Bluetooth functionality in end-use products. It outlines the Bluetooth elements that members are encouraged to convey and offers examples of how to effectively communicate those selected elements.  

2.1 Communication elements

End-use product companies are encouraged to utilize the communication elements listed below. Please note that while members often combine the Bluetooth wordmark with the Bluetooth® Core Specification version against which they qualified their product (e.g., Bluetooth 5.4) to indicate support for Bluetooth technology, the SIG does not endorse this, as it may lead to incorrect assumptions about supported Bluetooth functionality.
