Study of flow control based on bluetooth HCI UART transport layer

According to state sequence analysis method,constructs a flow control model based on HCI UART,presents a mathematical formula calculating flow control performance,and proposes a condition expression of optimal performance,which has more importance for decreasing bottleneck effect of HCI UART low bautrate and increasing bluetooth transport speed.Furthermore,develops a emulate software about flow control performance analysis,which indicates the correctness of theoretical analysis.
