Other Parts Discussed in Thread: MMWAVEICBOOST, , DCA1000EVM, IWR6843ISK
您好！我目前正在使用DCA1000EVM+MMWAVEICBOOST+IWR6843ISK-ODS的组合。目前使用py脚本进行数据采集，但出现了一些问题。在我向ICBOOST串口发送'sensorStart'命令时，板子没有反应。再发送'sensorStop'命令时，串口报错b'Debug: Init Calibration Status = 0x1ffe\n\rError -1\n\rmmwDemo:/>sensorStop\nIgnored: Sensor is already stopped\n\rDone\n\rmmwDemo:/>'。我的config.py和record.py文件如下：# config.py
