Server-Side Application of the Project

Welcome to the server-side of my project, developed using C++ and PlatformIO. This application runs on the Olimex ESP32-EVB development board and incorporates robust security protocols for secure communication.

Key Components

The server-side application is organized into the following C++ modules:

  1. Session Module - Manages client sessions, particularly ensuring efficient handling of a single session at a time, as per project requirements. It also handles advanced security measures, including HMAC-SHA256, AES-256, and RSA-2048 encryption protocols, to secure data transmission.
  2. Communication Module - Handles the communication protocol with the client, using secure methods as specified in the project requirements.
  3. Main Source - The main source file that orchestrates the server-side application, including session management and communication handling.

Features

The server-side offers functionalities including:

  • LED Control: Manages the LED states based on client requests.
  • Temperature Reporting: Retrieves and sends temperature data from the ESP32's sensors to the client.
  • Session Management: Handles session creation, maintenance, and expiration, with a focus on single-session handling and automatic session expiration after a predefined period of inactivity.

Hardware

  • Olimex ESP32-EVB: This development board is the core of my server-side application, featuring Wi-Fi and Bluetooth capabilities, along with various input/output interfaces.

Dependencies

  • PlatformIO: An ecosystem for IoT development.
  • C++ Standard Libraries: For core functionalities.
  • Arduino Core: For ESP32 development.
  • ESP32-EVB Board Support: Specific libraries and drivers for the Olimex ESP32-EVB board.
  • mbedTLS: For implementing cryptographic functions like HMAC, AES, and RSA.

Installation and Setup

To set up the server-side application:

  1. Install PlatformIO Core: Follow the installation guide at PlatformIO Installation Guide.
  2. Clone the Repository: Obtain the project repository on your machine.
  3. Navigate to the Server Directory: Switch to the server directory in the terminal.
  4. Install Dependencies: PlatformIO automatically handles the dependencies when you build the project.

Building and Running the Server

To build and run the server-side application on the ESP32-EVB:

  1. Build the Project: Execute platformio run in the server directory to compile the project.
  2. Upload to the ESP32-EVB: Use platformio run --target upload to upload the compiled code to the Olimex ESP32-EVB board.
  3. Makefile: You can also use the provided Makefile to build and upload the project. Run make to build and make client to upload the code to the board.

With this setup, you are ready to deploy and operate the server-side of my project on the Olimex ESP32-EVB development board!
