Bespoke Controller connection to Unreal Engine via Arduino & UDP

Description

I have developed a custom controller using conductive thread and embroidery to interact with an Unreal Engine environment. The controller uses touch inputs to trigger actions such as WASD movement and rotation.
The system consists of:- Arduino Code: ESP32 touch capacitive code written in Arduino IDE, currently functional and stable.- UDP Communication: A custom UDP blueprint in Unreal Engine that extracts a JSON file to read touch data. This integration is working successfully.
This project will be traveling to multiple countries, requiring adjustments to account for varying setups such as Wi-Fi configurations, triggers, and noise thresholds. The technicians installing the work are not proficient in coding or Unreal Engine, so the system needs to be refined for ease of use and supported by thorough documentation.
Additionally, the UDP blueprint should be made reusable as a drag-and-drop asset for future Unreal Engine projects, with clear instructions for customization (e.g., modifying triggers).
Key Goals- Ensure key variables (e.g., noise threshold and Wi-Fi setup) are centralized and easy to modify. Provide clear comments and instructions for technicians to edit these settings.- Optimize for reusability as a drag-and-drop asset for future projects.- Document how to modify triggers and input settings for custom interactivity.- Include step-by-step setup instructions for both the Arduino and Unreal Engine components.- Highlight specific lines or sections in the code and blueprint that require editing when location has changed.- Provide troubleshooting tips for common issues, such as connectivity problems or sensitivity adjustments.
The heavy lifting in terms of coding and testing is already complete. The focus now is on refining the existing system, improving usability, and creating clear, accessible documentation to ensure the work can be seamlessly deployed and customized by technicians worldwide.
