I’m working on an embedded system project using the Wio terminal, which is to design a wifi packet sniffer. I have been searching the internet for any projects related to this, using the Wio terminal or the RTL8720DN wifi module, but I haven’t found any that fit what I need. I have seen some projects that use the ESP32 to design a packet sniffer, but I wanted to know if it was possible to create a packet sniffer using the RTL8720DN. I’ve been looking through the documentation, but I haven’t found any information that I can use to design a packet sniffer. The RTL8720DN can do promiscuous mode, but I haven’t found any way to manage the captured packets. If there is a way to manage the captured packets, I would like to send them over serial.
My main question is: Is it possible to make a wifi packet sniffer with the Wio Terminal? If so, how would I go about doing it, and what resources can help me design it?
