Abstract: Based on analysis of RFCOMM transport protocol, connection model and procedure of communication, this paper presents a RFCOMM-L2CAP asynchronous communication structure based on Finite State Machine(FSM) and a multiplexing model of L2CAP channel as RFCOMM unique transport layer, maintaining a reference relationship between RFCOMM connections and L2CAP logic channel through asynchronous handling of event, optimizing the efficiency of information exchange and real time between layers of Bluetooth protocol stack.
