Bluetooth have different protocols as core protocols,Replacement protocol, Telephony control protocol and advance protocols. The details are given belows.
1.
Bluetooth
Core Protocols
Ø Baseband
– enables physical RF link
Ø Link
Manager Protocol (LMP) – manages devices in range, power modes, connections,
duty cycles, etc.
Ø Logical
Link Control and Adaptation Protocol (L2CAP)
segmentation and re-assembly of fragmented packets with their
multiplexing
Ø Service
Discovery Protocol (SDP) – Enables a device to join a piconet
2. Cable Replacement Protocol
Ø Radio
Frequency Communication (RFCOMM) - emulates RS-232 control and data signals
over Bluetooth baseband protocol.
3. Telephony Control Protocols
Ø Telephony
Control Specification Binary (TCS BIN) – defines the call control signaling
protocol and handles mobility management for groups of Bluetooth TCS devices
Ø Attention
(AT) Commands - defines a set of commands by which a mobile phone can be used
and controlled as a modem for fax and data transfers
4. Adopted Protocols
Ø Point-to-Point
Protocol (PPP) - means of taking IP packets to/from the PPP layer and placing
them onto the LAN
Ø Transmission
Control Protocol/Internet Protocol (TCP/IP) -used for communication across the
Internet
Ø Object
Exchange (OBEX) Protocol - session protocol to exchange objects and used to
browse the contents of folders onremote devices
Ø Content
Formats - used to exchange messages and notes and synchronize data amongst
various devices.
