ESP8266 – WiFi sniffer

This is my another example of simple and inexpensive WiFi packet analyzer (also known as a WiFi sniffer). The heart of this project is ESP8266 WiFi module which is able to work in a promiscusous mode. This module allows IEEE802.11 network packets capturing for further analyzing. Because of the fact that ESP modules don’t listening on all channels at a time, additional code … Read more

ESP32 – WiFi sniffer

This experimental project shows how to build a simple and inexpensive WiFi packet analyzer (also known as a WiFi sniffer). The heart of this project is WiFi module of ESP32 which is able to work in a promiscusous mode. It means that this clever chip allows IEEE802.11 network packets capturing for further analyzing. Because WiFi … Read more
