Hello everyone,

I am trying to run the iPerf example as I would need it to test a netwok including some ESP32 units. However, at the moment I am a bit lost on how to proceed after flashing the example (https://github.com/espressif/esp-idf/tr ... wifi/iperf)

So, following the steps indicated in the example:

1. I configured example
2. I build the example and I am ready to run the test
3. Then, I don't understand how to go on and "Run the demo as station mode and join the target AP sta ssid password" and I currently stuck.

Thank you in advance to anyone available for some clarification!
