Logical Link Control and Adaptation Protocol (L2CAP) − L2CAP provides adaption between upper layer frame and baseband layer frame format. The other main functions of LMP are device authentication, message encryption, and negotiation of packet sizes.

Link Manager Protocol (LMP) − LMP establishes logical links between Bluetooth devices and maintains the links for enabling communications. It defines the addressing scheme, packet frame format, timing, and power control algorithms. It defines air interface, frequency bands, frequency hopping specifications and modulation techniques.īaseband − This protocol takes the services of radio protocol. Radio − This is a physical layer equivalent protocol that lays down the physical structure and specifications for transmission of radio waves. The following diagram shows the Bluetooth protocol stack − The commonly adopted protocols used in Bluetooth are Point-to-Point Protocol (PPP), Internet Protocol (IP), User Datagram Protocol (UDP), Transmission Control Protocol (TCP), and Wireless Application Protocol (WAP).

It provides a serial interface with WAP.Īdopted Protocols − These are the protocols that are adopted from standard models. It is short for Radio Frontend Component. Protocols in the Bluetooth Protocol StackĬore protocols − This includes Bluetooth radio, Baseband, Link Manager Protocol (LMP), Logical Link Control and Adaptation Protocol (L2CAP), and Service Discovery Protocol (SDP).Ĭable Replacement Protocol − This includes Radio Frequency Communications (RFComm) protocol. This is because Bluetooth is designed to be used by myriad applications and the application designates which part of the protocol stack is to be used. Another unique feature is that it is not mandatory for all the devices in the Bluetooth system to use all the protocols in the stack. The Bluetooth architecture has its own independent model with a stack of protocols, instead of following the standard OSI model or TCP/IP model. Bluetooth network technology connects mobile devices wirelessly over a short-range to form a personal area network (PAN).
