ArduinoPcap
An Arduino library for creating and sending .pcap files from ESP8266/ESP32 to Wireshark for WiFi packet capture and analysis.
What is ArduinoPcap?
ArduinoPcap is an Arduino library that allows ESP8266 and ESP32 microcontrollers to capture WiFi packets and output them in the .pcap format, compatible with Wireshark. It enables embedded devices to act as low-cost network sniffers for monitoring WiFi traffic, detecting deauthentication attacks, or analyzing network behavior.
Embedded developers, security researchers, and hobbyists working with ESP8266/ESP32 who need to capture and analyze WiFi packets for projects like intrusion detection, network monitoring, or educational demonstrations.
It provides a simple, Arduino-compatible way to perform packet capture on affordable hardware, eliminating the need for expensive commercial sniffing tools. The library includes live Wireshark streaming and SD card logging, making it versatile for both real-time and offline analysis.
