Overview

This is the firmware for followifier boards.

How it works

1. Board starts sniffing and storing packets
2. Upon reaching a certain amount of stored packets:
   1. Board stops sniffing
   2. Board connects to the Wi-Fi network
   3. Board flushes all the data to the core server
   4. Board disconnects from the Wi-Fi network
3. Board starts sniffing again

Configuration

1. Run the core server and take note of its IP address and port
   • More instructions on how to do it here
2. Set the Wi-Fi SSID, the Wi-Fi password, and the core server's IP address and port in main/util/conf.h
   • You can see known Wi-Fi networks' details on Linux by using:

     $ sudo cat /etc/NetworkManager/system-connections/<SSID> | grep 'ssid=\|psk='

3. Clean, compile, flash and run the software on all boards, one at a time:

   $ idf.py fullclean && idf.py build && idf.py -p <port> flash monitor 

   Where <port> indicates the serial port to which the ESP32 board is connected to (e.g., "COM3" on Windows or "/dev/ttyUSB0" on Linux)
   • You can list all connected boards on Linux with:

     $ ls /dev/ttyUSB*

4. To exit IDF monitor use the shortcut Ctrl+]
