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.
