OTA_ESP32

Creating a secure ESP32 OTA update manager and bootloader based on a Python server, MySQL and using TCP connections to communicate with the device

Goal :

• The GUI is easy to use and intuitive
• The system is easy to set up and secure
• The code is easy, coder-friendly, made to be upgraded

Prerequisites :

• Arduino IDE with the Crypto library
• Python3 (with mysql-connector-python, pysimplegui and pycryptodome)
• MYSQL server

How to use :

• Clone the project
• Import the MYSQL database
• Modify the Python Server.py and GUI.py parameters depending on your Mysql database authentification and execute them.
• Modify the ESP32 parameters depending the device and networking informations you want and upload the code on your device
• On the GUI, authorize the devices you want, add the updates and activate them.

Known bugs :

• Memory corruption can occur.
• Errors when uploading firmware (several tries expected)
• Display not working for both server and esp32

Known vulnerabilities :

• The binary update is not encrypted
• The encrypted identification can be heard and repeated on another device
