    Study Notes

    Bluetooth Technology: RF Band, Access Method, Piconet, Scatternet, Packet Format, Baseband, Operational States, Energy Management, MAC Address, Protocol Stack

    • Bluetooth operates on the 2.4 GHz ISM band with 79 (23) RF channels and 1 MHz carrier spacing.
    • Access method for Bluetooth is FHSS and TDD with frequency hopping of 1600 hops/s and time division duplex for send/receive separation.
    • Bluetooth-enabled electronic devices communicate wirelessly through short-range, ad-hoc networks known as piconets, which are formed by a master and up to 7 active slaves and up to 255 parked slaves.
    • Scatternet is the linking of multiple co-located piconets through the sharing of common master or slave devices, and devices can participate in multiple piconets.
    • Bluetooth packet format can be up to five slots long, with access codes for channel, device, and inquiry and a 18-bit header encoded using 1/3 rate FEC.
    • Bluetooth baseband includes low-level packet definition with access code and packet header, and operational states consisting of standby, inquiry, page, connected, hold, sniff, and park.
    • Transmit energy management for Bluetooth includes three inactive states: hold, sniff, and park.
    • Each Bluetooth device has a 48-bit IEEE MAC address with three parts: lower address part (LAP), upper address part (UAP), and non-significant address part (NAP).
    • The Bluetooth protocol stack includes Logical Link Control and Adaptation Protocol (L2CAP), Host Controller Interface, RFCOMM Layer, Service Discovery Protocol (SDP), Bluetooth Network Encapsulation Protocol (BNEP), and IrDA Interoperability protocols.
    • L2CAP provides protocol multiplexing, segmentation and reassembly, and controls peak bandwidth, latency, and delay variation.
    • Host Controller Interface allows the same software to run on all chips.
    • RFCOMM Layer presents a virtual serial port, sets up a connection to another RFCOMM, and allows devices to discover the services offered and their parameters through SDP.

    • It uses FHSS and TDD access methods with frequency hopping at 1600 hops/s and a hopping sequence determined by a master.
    • Bluetooth enables voice links through SCO with 64 kbit/s duplex, point-to-point, circuit switched connections with FEC but no retransmission.
    • Data links are enabled through ACL with asynchronous, fast acknowledge, point-to-multipoint, up to 433.9 kbit/s symmetric or 723.2/57.6 kbit/s asymmetric, packet switched connections.
    • Bluetooth devices connect and communicate wirelessly through short-range, ad hoc networks known as piconets, formed by a master and up to 7 active slaves with up to 255 parked slaves.
    • Scatternets are formed by linking multiple co-located piconets through the sharing of common master or slave devices, enabling communication between piconets.
    • Frequency hopping sequences use 625 µs slots with a 312.5 µs clock for time-division duplex downstream and upstream alternate transmission.
    • Bluetooth packet format includes access codes, 18b header encoded using 1/3 rate FEC, synchronous traffic with periodic reserved slots, and asynchronous traffic.
    • Bluetooth baseband includes low-level packet definition with channel and device access codes derived from the master and alternating bit ARQ/SEQ and checksum in the packet header.
    • Bluetooth operational states include standby, inquiry, page, connected, and three inactive states: hold, sniff, and park.
    • Each Bluetooth device has a 48-bit IEEE MAC address with a lower address part (LAP), upper address part (UAP), and non-significant address part (NAP) used in identifying the piconet and other operations.
    • The Bluetooth protocol stack includes L2CAP for protocol multiplexing and segmentation/reassembly, Host Controller Interface for chip-independent interface, RFCOMM layer for virtual serial port and service setup, SDP for service discovery, BNEP for Ethernet/IP packet transport, and IrDA interoperability protocols.
