The new Bluetooth Core 6.2 specification also introduces various BLE Test Mode enhancements. If you feel like Bluetooth specifications are released more often than in the past, that's normal because the Bluetooth SIG switched to a bi-annual release schedule. For instance, the Bluetooth 6.1 specification was just published last May, or about 6 months ago... Bluetooth 6.2 Bluetooth 6.2 highlights: * Bluetooth Shorter Connection Intervals (SCI) reduce the minimum Bluetooth LE connection interval from 7.5 ms to just 375 us for faster responsiveness. The change will especially impact high-performance HID devices, real-time human-machine interfaces (HMIs), and latency-sensitive sensors. AR/VR and gaming applications will particularly benefit from the lower latency. * Bluetooth Channel Sounding Amplitude-based Attack Resilience adds protections against sophisticated amplitude-based RF attacks. Devices for the automotive, smart home, and industrial markets will become less prone to relay and spoofing threats with the changes. * Bluetooth HCI USB LE Isochronous Support gets Bulk Serialization Mode, a new mechanism for standardizing isochronous data transmission over USB. With this update, host-controller interface (HCI) packet handling will be simplified, and it also streamlines LE Audio integration in Bluetooth USB devices. * Bluetooth LE Test Mode Enhancements enable a unified control protocol for performing Bluetooth LE RF PHY tests, while also supporting over-the-air (OTA) transport, so testers won't need to rely on cables anymore.

The Bluetooth 6.3 specification should be released sometime in May 2026 if they keep up with their bi-annual schedule.
