The Bluetooth Special Interest Group (SIG) has adopted a new version of the Bluetooth Core Specification (v6.0). The new v6.0 BT Core Spec includes a variety of new features and enhancements:
- Bluetooth® Channel Sounding: This feature enables distance awareness, for Find My solutions, making it easier and faster to locate lost items.
- Decision-Based Advertising Filtering: 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.
- Monitoring Advertisers: The host component of an observer device may instruct the Bluetooth LE controller to filter duplicate advertising packets.
- ISOAL Enhancement: 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.
- LL Extended Feature Set: Now larger numbers of features are supported when devices exchange information about the link-layer features that they each support.
- Frame Space Update: In version 6.0 of the Bluetooth Core Specification, frame spacing, as used in connections or with connected isochronous streams, is now negotiable and may be shorter or longer than 150 µs.
