IWR6843ISK: 运行traffic_monitoring可视化程序时端口可打开却无回复

Part Number: IWR6843ISK
Other Parts Discussed in Thread: MMWAVEICBOOST

我尝试运行mmwave_industrial_toolbox_4_8_0\labs\traffic_monitoring\18xx_68xx_traffic_monitoring的这个例程,按照使用说明的步骤进行操作。当运行GUI程序tm_visualizer.m的时候,提示端口能打开但是无法回复信息,请问如何解决呢?(板子的SOP都是照着教程做的,应该没问题)下面的代码是允许tm_visualizer.m时的输出
