Bluetooth Advances In Windows Vista And Beyond

1. Bluetooth Advances In Windows Vista And Beyond Vatsal BhardwajProgram ManagerWindows Device Experience GroupMicrosoft Corporation

2. Outline • Bluetooth advances in Windows Vista • Partner slides: CSR • Bluetooth features post Windows Vista • Partner slides: Dell Inc • Call to action

3. Core Stack Enhancements For Windows Vista • Synchronous connection oriented links • Channel avoidance • Radio class driver enabled by Microsoft OS descriptors • Pre-boot HID support for Bluetooth keyboards and mouse

4. Extensibility Improvements For Windows Vista • Logical link control adaptation protocol (L2cap) and Service discovery protocol (SDP) interfaces • Synchronous connection oriented links (SCO) interfaces • Device installation extensibility • Installation based on Bluetooth host controller (local) • Installation interfaces for Server-side profiles

5. Profiles On Windows Vista • Silicon agnostic headset and handsfree profiles available via Microsoft Updateon Windows Vista • Also available to PC OEMs for factory preinstall • Stereo audio profiles (A2DP, AVRCP) available on Windows native stack via Bluetooth silicon vendors • Microsoft update for stereo audio profiles currently being investigated • Other profiles (FTP, BIP, BPP) available via Bluetooth silicon vendors

6. New Logo Requirements For Bluetooth Radios On Windows Vista • Must support Bluetooth 2.0 + EDR specifications as defined by theBluetooth SIG • Microsoft plans to upgrade stackqualification to Bluetooth 2.0 + EDR • Must support synchronous connection oriented links as defined by theBluetooth SIG

7. Value Proposition of Bluetooth on Windows Vista • Consumers • Improved sync experience • Better coexistence with 802.11 • “Ultimate” Headset experience • Support for new Bluetooth radios • Support for high growth profiles

8. Value Proposition of Bluetooth on Windows Vista • OEMs and device vendors • Extensible platform and reduced time to market for partners developing custom solutions • Improved device coverage by Microsoft OS descriptors based radio class driver • Support for high growth profiles • Qualification update to Bluetooth 2.0 + EDR

10. CSR Vista Profile Pack • Adds profiles & features built on Microsoft Bluetooth APIs • Stereo Audio • A2DP & AVRCP Profiles • Works with both HID & Mono Audio • Additional VoIP clients for Mono Audio • Skype • Pre-boot HID • Allows mouse/keyboard connection in BIOS

11. CSR’s Experience • APIs are straight forward to use • Rich interface with good granularity • BRB interface follows familiar URB pattern • Limitations: • No RFCOMM access from kernel mode • No API for QoS (bandwidth management & allocation) • Error return codes for kernel mode APIs give limited information

12. Post Windows Vista Feature Considerations • Core stack enhancements • Simplified pairing • Standardized pre boot HID solution • Sniff Sub-rating • Quality of service • User experience • Revamp of overall user experience based on Simplified pairing • Improved dial-up networking and Internet connection setup experience

13. Post Windows Vista Feature Considerations • Inbox inclusion of high growth profiles • Headset and Handsfree profile • Stereo audio profiles (A2DP, AVRCP) • Other profiles which customers request • Additional developer support • New samples for SDK • Function discovery integration (consistent APIs to discover Bluetooth devices)

14. Post Windows Vista Logo Requirements & Considerations • Bluetooth 2.0 + EDR requirementsfor HID, Printers and Headsets • Microsoft OS descriptors requirementfor Bluetooth radios • Logo program for Bluetooth headset devices
