.. _rndis_host_iperf: RNDIS Host - IPERF ==================================== 概述 ------ - 本示例工程展示USB RNDIS Host实现连接合宙4G模块-air780e模块或者EC20模块联网,并进行iperf测速。 硬件设置 ------------ - 开发板的USB0通过USB线连接合宙4G air780e模块或者EC20模块。 - 开发板(RNDIS Host)的DEBUG口或UART Console口接于PC。 运行现象 ------------ - 将程序分别下载至开发板中，并接好连线，开发板(RNDIS Host)串口控制台输出如下，表示air780e模块已经初始化成功，若没有则检查上模块是否上电 .. code-block:: console Start rndis host iperf task...
