5.45. RNDIS Host - IPERF
5.45.1. Overview
This sample demonstrates USB RNDIS Host network connectivity with Luat 4G modules (air780e), EC20 modules, or ML307R modules, and performs iperf network speed testing
5.45.2. Board Setting
Development board connected to air780e/EC20/ML307R via USB0 port using USB cable
Debug port or console port of RNDIS Host connected to PC
5.45.3. Example of output log
When programming the development board and connecting air780e, the board will display the following logs on the serial console (if not, check if the module is powered on):
