FlexComm – Modular Multi-Protocol Communication Framework for Unity video 1 (plays on the Asset Store)
About this asset
FlexComm is a protocol-agnostic, cross-platform communication framework for Unity, designed to simplify and unify external device and service integration across platforms. It supports MQTT, REST, UDP, TCP, Serial, and WebSocket communication—all configurable via a clean Unity Editor interface. One Component serves as the interface for all protocols!
Whether you're building XR-based robot control systems, industrial simulations, or research applications, FlexComm enables seamless data routing, message handling, and cross-protocol flexibility. The system is modular, extensible, and fully customizable to suit project-specific needs, with built-in editor tools and runtime diagnostics to accelerate development and ensure reliability.
FlexComm is the spiritual successor to DTStacks, a Unity-based MQTT framework originally developed for human-robot interaction and simulation. DTStacks was featured in a peer-reviewed academic publication (see doi:10.1016/j.procir.2024.10.165) and used in multiple robotics research projects. FlexComm expands on that foundation with a fully reworked, protocol-agnostic architecture, broader platform support, and advanced integration features. However, it was designed to also be used by non Unity experts like students and features easy to use editor components and scripts while offering advanced interactions using a unified API.
FlexComm has already been adopted in numerous academic publications and ongoing research projects, serving as the backbone for multimodal communication in XR, robotics, and digital twin systems. Some use cases are presented in the videos above!
Free Companion Toolkit
Includes FlexComm-Lab, an open-source GitHub project with test tools, protocol simulators, and example integrations to accelerate your development (e.g. minimalist REST, Websocket, etc. - servers which can be run using Python 3.13). This also serves as a Wiki for FlexComm as well as an issue tracker with the main package! This will be updated and expanded as developments progress. Including experimental features, new extensions, etc.. This includes an integration for ROS and ROS2! (ROS side bridge is coming sonn!)

Technical details
Multi-Protocol Support
Integrates MQTT (v3.1.1 & v5.0), REST, UDP, TCP, Serial, and WebSocket communication directly within Unity.
Unified Interface
Use a single FlexClient component to switch between protocols without modifying your application logic—even during runtime.
Modular & Extensible Architecture
Easily add custom message handlers, stream processors, or entirely new protocols through clearly defined extension points.
Cross-Platform Compatibility
Supports Desktop, Mobile, WebGL, and UWP (including HoloLens 1 & 2), with automatic WebSocket fallback where needed.
Advanced Messaging Features
Includes MQTT QoS levels, retained messages, and Last Will & Testament for fault-tolerant and persistent messaging.
Editor Integration
Real-time Unity Editor tools for diagnostics, test messaging, connection monitoring, and auto-connect configuration.
XR & Robotics Ready
Built for XR, robotics, and simulation environments—successfully used on Quest, HoloLens, and real robot platforms.
Production & Research Proven
Field-tested in both industrial deployments and academic research, including peer-reviewed HRI and digital twin projects.
Quick Start & Customization
Comes with prefabs, runtime configuration options, and a clean, developer-friendly API for fast integration.
Unity Compatibility
Supports Unity 2021.3 LTS and newer. Can be used with .NET Standard 2.1 but .NET Framework is recommended since .NET Standard does not offer Serial support.
