WiFi is almost everywhere. Wherever you go there are WiFi packets emitted by smartphones, tablets, computers, access-points, etc. All WiFi packets “flying” around are divided into four main groups (802.11 Frame Types) – management, data, control and extension. In this article we will take care of capturing some interesting subtype packets of management group (Beacon … Read more
The common method of making a packet sniffer in User-Space is to use low-level operations on RAW sockets. But, instead of that, you can just use a powerful Python library – Scapy (see documentation), which exposes a user-friendly high level API. So, it hides all unfortunately low-level abstraction which we don’t really like in Python. … Read more
This version of DFT algorithm has been tested with success on a various microcontrollers (AVR – including ATtiny13, STM32 and ESP8266). The code is relatively simple and short what makes it easy to port to other programming languages / microcontrollers. In this tutorial I will open the black-box and show you some practical information about how this algorithm works and how to use … Read more
