Interoperability

Profiles

Profile: base for BT interoperability (BT too much flexible!).

“vertical cut” in Bluetooth stack.

A given usage model (typical solution).

Each BT device supports one or more profiles.

V.1

Generic Access.

  • Profile SDA.

    • (service discovery application).

  • Profiles for serial port, including:

    • Profile Dial-up.

    • Profile Fax.

    • Profile headset.

    • LAN Access (uses PPP).

    • Profile for generic object exchange (OBEX).

      • File transfer.

      • Data synchronization.

      • Push-pull.

Profile of coordless phone(TCS_BIN).

  • Profile interphone.

  • Profile Cordless Telephony.

V.2

Radio 2 (next generation radio).

  • Compatible with existing systems.

Car Profile.

PAN Profile.

GPS Profile.

Printing Profile.

Still image Profile.

  • (globally better facilities in audio/voice/video).

  • (better service discovery).

  • (improved human interfaces).

  • (improved interoperation with other devices at the 2.4GHz ISM).
