As part of the bi-annual release cadence, Bluetooth® Core 6.2 has arrived. This update introduces new features that enhance device responsiveness, strengthen security, and improve communication and testing capabilities. Together, these advancements reinforce the Bluetooth Special Interest Group’s (SIG) commitment to continuous innovation and provide developers with tools to meet evolving market demands.
Key features at a glance
Bluetooth® Shorter Connection Intervals reduces the minimum Bluetooth® LE connection interval from 7.5 ms to just 375 µs, enabling much faster responsiveness. It is ideal for high-performance HID devices, real-time human-machine interfaces (HMIs), and latency-sensitive sensors.
Bluetooth® Channel Sounding Amplitude-based Attack Resilience adds robust protections against sophisticated amplitude-based RF attacks. This enhancement strengthens secure ranging systems and mitigates relay and spoofing threats — critical in automotive, smart home, and industrial applications.
Bluetooth® HCI USB LE Isochronous Support introduces Bulk Serialization Mode, a new mechanism for standardizing isochronous data transmission over USB. This update simplifies host-controller interface (HCI) packet handling and streamlines Bluetooth® LE Audio integration for USB-based systems.
Bluetooth® LE Test Mode Enhancements enables a unified, future-proof control protocol for performing Bluetooth® LE RF PHY tests, while also supporting over-the-air (OTA) transport, eliminating the need for a cabled test setup.
Supporting the release with clear, accessible resources
To help developers and stakeholders better understand the new features, the Bluetooth SIG has prepared a dedicated Bluetooth® Core 6.2 feature overview paper that includes background context and technical details for each enhancement. Members are also encouraged to refer to the communication guide for supported Bluetooth® functionality to ensure accurate and consistent use of technical terminology in public-facing materials for qualified products. The guide supports unified communication across the industry, helping member companies clearly and effectively convey Bluetooth functionality.
Reminder: Bluetooth SIG members should avoid referencing the Bluetooth® Core Specification version against which a product was qualified (e.g., Bluetooth® Core 6.2) when describing Bluetooth functionality. Instead, members should focus on clearly communicating the specific Bluetooth capabilities (e.g., Bluetooth features) supported, especially those most relevant to your target customers, in product packaging, documentation, and marketing materials.
