The Bluetooth Particular Curiosity Group (SIG) has introduced its second, and final, replace to the Bluetooth Core specification of the 12 months: Bluetooth Core 6.2, which goals to spice up responsiveness, shield towards a novel type of assault, and simplifies host-controller interface packet dealing with for higher Bluetooth Low Power (BLE) audio.
“As a part of the bi-annual launch cadence, Bluetooth Core 6.2 has arrived,” says Bluetooth SIG’s Avi Negrin of the brand new specification. “This replace introduces new options that improve system responsiveness, strengthen safety, and enhance communication and testing capabilities. Collectively, these developments reinforce the Bluetooth Particular Curiosity Group’s (SIG) dedication to steady innovation and supply builders with instruments to meet evolving market calls for.”

The brand new launch comes six months after the launch of Bluetooth Core 6.1 — solely unsurprisingly, because the Bluetooth SIG not too long ago adopted a bi-annual schedule that sees its specs up to date twice a 12 months, making Bluetooth Core 6.2 the final replace of 2025. The place Bluetooth Core 6.1 got here with tweaks designed to spice up energy effectivity and improve privateness, Bluetooth Core 6.2 has an extended listing of latest options — beginning with the reducing of the minimal Bluetooth Low Power (BLE) connection interval from 7.5ms to 375µs, which the Bluetooth SIG says will enhance responsiveness for gadgets together with mice, keyboards, sport controllers, and “latency-sensitive sensors.”
One other characteristic of the brand new replace is the introduction of a discrete Fourier rework (DFT) detection system for a novel assault towards Bluetooth Channel Sounding-based ranging programs, which measure the space between Bluetooth gadgets however have confirmed susceptible to relay and spoofing assaults based mostly on amplitude modification. Bluetooth 6.2 additionally introduces a bulk serialization mode for USB-based host-controller interface (HCI) programs, which the SIG says will streamline Bluetooth LE Audio integration, and enhancements to the Bluetooth LE Check Mode together with the adoption of a “future-proof management protocol” for bodily layer checks and wi-fi Over-The-Air (OTA) replace assist.
Technical particulars of the brand new options can be found on the Bluetooth SIG web site; the usual itself is offered at no cost obtain on a separate web page.
