The Bluetooth Technology Alliance (Bluetooth SIG) officially released the Bluetooth Core 6.2 specification today. As part of a fixed upgrade rhythm twice a year, this version brings a number of important new features to further improve device response speed, security, and communication and testing capabilities. These new features once again demonstrate the Bluetooth SIG's commitment to continuous innovation and provide developers with new tools to respond to changing market needs.
The main updates of Bluetooth Core 6.2 include:
Bluetooth ultra-short connection interval: Reduces the minimum interval for Bluetooth Low Energy (LE) connections from 7.5 milliseconds to only 375 microseconds, greatly improving response speed. This feature is especially suitable for high-performance human-machine interface devices (HID), real-time human-machine interaction systems (HMI) and delay-sensitive sensors.
Bluetooth channel ranging and anti-amplitude attack enhancement: A stronger protection mechanism has been added for complex amplitude-based radio frequency attacks. This upgrade significantly improves the security of the safe ranging system, effectively prevents relay and spoofing attacks, and is suitable for automobiles, smart homes, and industrial scenarios.
Bluetooth master USB LE isochronous transmission support: Introducing Bulk serialization mode, standardizing the isochronous data transmission process in the USB environment, simplifying host control interface (HCI) data packet processing, and facilitating the integration of Bluetooth LE audio in USB devices.
Bluetooth LE test mode enhancements: Provides a unified and scalable control protocol for Bluetooth LE radio frequency physical layer (RF PHY) testing, and supports over-the-air (OTA) test transmission without the need for a traditional wired test environment.
In order to help developers and related industry partners better understand the new version of the specification, the Bluetooth Technology Alliance simultaneously released the "Bluetooth Core 6.2 Function Overview" technical white paper, which details the background and technical details of various improvements. Alliance members can also refer to the "Bluetooth Function Communication Guide" to ensure accurate and unified product information and effectively promote industry standardization communication.
The Bluetooth SIG also reminds member companies to avoid directly labeling the Bluetooth core specification version used by the product (such as Bluetooth Core 6.2) in product packaging, documentation and marketing promotions. Instead, they should focus on clarifying the Bluetooth features actually supported by the product so that users and customers can accurately understand the core capabilities and functional highlights.
