Esp32 and wifi laboratory test.

Hi, the new device based on esp32 is completed.
Now we have to make the wifi trasmissions test in an anechoic room.
I need a way to generate a sequence of wifi packets with a specified interfame time.
Can someone give me an example on how to do that?
Many thanks.

Regards.

works in main.c but not in test01.h of the component
