ESP8266 PCAP Sniffer - RTOS SDK Version

ESP8266 Sniffer firmware which outputs PCAP data via UART. Use the sniffer to stream 802.11 packets from ESP8266 to Wireshark or dump into a PCAP file.

Overview

An ESP8266 RTOS-SDK based firmware which sniffs 802.11 packets using your ESP8266 and streams it to Wireshark via the UART driver.

Note: Only 802.11 packets are sniffed atm. Change to your liking.

Compile & Flash

You should have the RTOS SDK installed. Go to the examples/wifi path and clone this project. Enter the project directory, change the sniffer options on the menuconfig, compile and flash:

cd $IDF_PATH/examples/wifi
git clone https://github.com/z4ziggy/esp8266_pcap_uart.git
cd esp8266_pcap_uart
make menuconfig
make -j8 flash

Run SerialShark.py to forward the PCAP stream from the ESP8266 to Wireshark:

./SerialShark.py
