摘　　要：根据停-等流控原理构造了一种基于蓝牙HCIUART传输层的流控模型,并对该模型进行了流控效率的分析,给出了流控效率的数学表达式,提出了最佳流控效率的条件表达式,这对降低HCIUART低速率的瓶劲效能和提高蓝牙数据传输速率具有指导意义。在上述分析基础上,开发了一个基于HCIUART流量控制性能分析的仿真软件,仿真实验结果符合流控效率的理论分析。Abstract： According to stop-wait flow control mechanism, a flow control model based on HCI UART is constructed, exactly performance analysis about the model is given, a mathematical formula calculating flow control performance is presented, and a condition expression of optimal performance is proposed, which has more importance for decreasing bottleneck effect of HCI UART low baud rate and increa- sing blue tooth transport speed. Furthermore a emulate software about flow control performance analysis is developed, which indicates the correctness of theoretical analysis.
