Now Available: New Version of the Bluetooth Core Specification
Bluetooth Core Specification version 6.0 continues the trend for Bluetooth technology to be regularly updated with new features and technical improvements. Bluetooth Channel Sounding will enable a standards-based, secure approach to reliable and accurate distance measurement and many types of products will benefit. Decision-based advertising filtering will improve throughput and reliability when using Bluetooth extended advertising for connectionless data transfer. Monitoring advertisers will be useful to application developers and enable the provision of better user interfaces and an improved user experience. The improvements made to ISOAL will benefit audio applications for which low latency is important. And the LL extended feature set capability enables feature support discovery in the most sophisticated, feature-rich devices.
The user experience of Find My solutions can be greatly improved, making it easier and faster to locate lost items. In digital key solutions, Bluetooth Channel Sounding will add a robust layer of security, ensuring that only authorized users within a specified range can unlock doors or access secure areas. And, by infusing billions of everyday devices with true distance awareness, Bluetooth® Channel Sounding unlocks a world of possibilities for developers, freeing them to imagine and create innovative experiences that will continue to enhance our connection with our devices, one another, and the world around us.
The Bluetooth Low Energy (LE) Extended Advertising feature supports a series of related packets being transmitted on both primary and secondary radio channels. Decision-based advertising filtering allows a scanning device to use the content of a packet received on a primary advertising channel to decide if it should scan for related packets on the secondary channels, improving scanning efficiency by reducing the time spent scanning on secondary channels for packets that might not contain PDUs relevant to the application.
The Isochronous Adaptation Layer (ISOAL) makes it possible for larger data frames to be transmitted in smaller link-layer packets and ensures the associated timing information that is needed for the correct processing of the data by receivers can be reconstituted. ISOAL can produce either framed or unframed PDUs depending on certain variables. If framed PDUs are produced, latency can be increased as a result. In Bluetooth Core Specification version 6.0, ISOAL has been improved by defining a new framing mode that reduces latency for use cases that are particularly sensitive to this issue. The same feature also improves reliability.
LL Extended Feature Set: With this advancement, devices can exchange information about the link-layer features that they each support. This capability has been enhanced to support larger numbers of features, which has become necessary as the sophistication and versatility of Bluetooth LE have grown.
