The Bluetooth Technology Alliance has introduced a biannual release cycle for the Bluetooth Core Specification, enabling faster and more consistent delivery of new features. This change accelerates innovation within the Bluetooth ecosystem, allowing developers and manufacturers to access the latest advancements promptly and respond efficiently to market demands. The first version under this new cycle, Bluetooth Core Specification 6.1, was released on May 6, 2025, introducing significant improvements in privacy and energy efficiency.
Biannual Release Cycle
The shift to a twice-yearly release schedule for the Bluetooth Core Specification ensures that developed features are delivered more rapidly to the ecosystem. Alain Michaud, Chair of the Bluetooth Technology Alliance Board, stated that this change enables developers and manufacturers to address evolving market needs more effectively, fostering continuous technical optimization and wireless innovation.
Key Features of Bluetooth Core Specification 6.1
Bluetooth Core Specification 6.1 introduces the Bluetooth Randomized Resolvable Private Address (RPA) update, designed to enhance device privacy and energy efficiency. The key benefits include:
- Improved Privacy: Randomized address change intervals make it more difficult for third parties to track or associate a device's long-term activity.
- Enhanced Energy Efficiency: Offloading address change operations to the controller reduces power consumption, extending battery life.
Updated Promotional Guidelines
Alongside the release, the Bluetooth Technology Alliance has added a new feature description appendix to its promotional guidelines. This appendix provides a clear overview of Bluetooth features, profiles, and applications, ensuring accurate and consistent communication. It helps member companies precisely convey their products' Bluetooth capabilities, promoting standardized industry communication.
Guidance for Manufacturers
The Bluetooth Technology Alliance advises members to avoid referencing specific Bluetooth Core Specification version numbers, such as 6.1, in product descriptions. Instead, manufacturers should clearly and accurately describe the supported Bluetooth features in product packaging, documentation, and promotional materials, focusing on aspects most relevant to user needs.
