Bluetooth RF Comm Diagram
RF Comm is is the transmission of information and control commands from one communication device to another communication device (such as from a computer to an accessory device) that is performed serially (one bit at a time). The Bluetooth system uses radio frequency communication (RFComm) protocol to setup and coordinate the transfer of serial data.

Radio Frequency Communication - RFComm is a set of commands and process that are used to emulate the operation of a serial communication port. It is capable of simulating the software and hardware (wire voltage level sensing) operations of RS-232 (EIA/TIA-232-E) serial ports and is based on ETSI TS 07.10.

This figure shows how the RFComm protocol can be used to emulate a wired connection between a serial mouse and a standard computer RS-232 port. This example shows that the computer requests an RS-232 connection request to the Bluetooth radio through the RF communication port. The RFComm protocol determines the need for a communication session so it requests that the L2CA layer initiate a logical connection to the mouse Bluetooth radio. Once the logical channel is created between the laptop computer and the Bluetooth mouse, the RFComm protocol is used to establish the parameters (settings) of the serial connection (data rates and connection control type). The RFComm protocol then continually receives serial data from the mouse, identifies (addresses) and packetizes the data, and sends it to the laptop computer.

Introduction to Bluetooth Book

This book explains how Bluetooth devices can locate, authenticate, discover the capabilities, and setup connections with other Bluetooth devices. Radio packet structures, modulation types, and protocols are described and explained along with Bluetooth security pairing (authentication) and privacy (encryption) processes.
