1、将SIM7020X NB-IoT HAT接入Jetson Nano中,按下PWRKER键两秒后开机 2、使用SERIAL登录Jetson Nano终端,安装minicom,在终端下输入: sudo apt-get install minicom 3、运行minicom进行串口调试,在终端下输入 sudo minicom -D /dev/ttyTHS1 -b 115200 4、 发送AT指令测试,退出时按下PWRKEY按键三秒后开始关机,...
这里看到 的USB-SERIAL CH341A (COM3 ),说明新生成的串 为COM3 ,那么在以后的使用中,凡 是要用到串 的,就要用COM3. 9 .可以双击USB-SERIAL CH341A (COM3 )展开进行 的设置,如下图所示,但通常这 是不必要的,除非你对串口设置非常熟悉,否则不要轻易改变设置。 10.单击端口设置,可以查看其设置情况,但...
