ESP8266 – WiFi beacon spammer

In this article I will show you how to make a WiFi  beacon spammer on ESP8266. Beacon spamming involves broadcasting a valid IEEE 802.11 beacon frames using fake SSIDs and MAC addresses. This educational project is hackable and easy to get running. The code is on GitHub, here. What is WiFi Beacon? WiFI beacon frames are used by … Read more

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

ESP8266 – building the toolchain for Linux (Ubuntu)

This is a quick tutorial that shows how to build a complete development environment (including FreeRTOS support) for the ESP8266 processors on Linux. These instructions have been tested successfully on Ubuntu 17.04. UPDATE (05.03.2019) If you want to use FreeRTOS in your project I recommend to install a new version of ESP8266_RTOS_SDK (esp-idf style) Building Toolchain Step-by-Step All … 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
