在工業自動化領域中，運行於不同作業系統（如 Windows 和 Linux）的裝置常見於同一應用場域中。為提升操作便利性，iOS 與 Android 裝置也經常被納入，進一步加劇了跨平台無線通訊的挑戰。此外，部分裝置因為物理限制、行動性需求或設計因素，不適合透過 USB 或外部周邊進行資料傳輸。傳統網路協定（例如 TCP/IP）通常需要手動設定，且缺乏自動化與跨平台的連接能力。
像是藝術展覽這類的大規模應用場景，需仰賴能穩定支援大量裝置的廣域網路，同時要求快速建置、最少佈線，以及能因應主題或展場配置變更的彈性。
本論文提出一種跨平台的群組通訊協定，整合 Wi-Fi 與 Bluetooth Scatternet 技術，以建立具可擴展性與容錯能力的異質裝置無線 Mesh 網路。我們亦開發多平台 SDK，簡化網路層整合流程，並實現應用層控制。系統原型已於 Windows、Android、iOS 與嵌入式 Linux 平台上完成實作，並透過連線建立時間、錯誤回復時間與資料吞吐量等效能指標進行驗證，證實本系統在動態環境中的穩定性與效能表現。

In industrial automation, the widespread presence of devices running diverse operating systems, including Windows, Linux, iOS, and Android, creates significant hurdles for seamless, high-speed wireless communication. Traditional data transfer via USB or peripherals is often impractical due to physical constraints or mobility needs, while conventional network protocols such as TCP/IP demand manual setup and lack inherent cross-platform connectivity. For large-scale deployments like art exhibitions, there's a critical need for reliable, wide-area networks that offer rapid setup, minimal cabling, and adaptability. This thesis addresses these challenges by introducing a novel cross-platform group communication protocol that integrates Wi-Fi and Bluetooth Scatternet to form scalable, fault-tolerant mesh networks among heterogeneous devices. We've developed multi-platform Software Development Kits (SDKs) to simplify network-layer integration and enable application control. Prototype implementations on Windows, Android, iOS, and embedded Linux, alongside performance evaluations of connection setup time, recovery time, and throughput, consistently confirm the system's efficiency and robustness in dynamic environments.
