The RA4M2 handles high-speed sampling of sensor data and transmits the aggregated data stream to the Wi-Fi module—equipped with a built-in Tuya protocol stack—via a UART interface. The module communicates bidirectionally with the Tuya Cloud Platform through a TLS-encrypted channel, allowing real-time synchronization of uploaded Data Points (DPs) to the cloud, as well as reception of control commands from the app or a custom backend. With the Tuya IoT platform, developers only need to define the data model (DP) once in the console, download the MCU SDK, and implement a small portion of the underlying HAL. This enables completion of an end-to-end demo—from hardware to mobile app—within just a few days. In the Tuya Smart App or a custom backend based on MQTT/HTTP, developers can monitor historical trends in real time and issue commands as needed. With this solution, you can achieve integrated deployment of hardware, firmware, and cloud services within 1–2 days, enabling visual management and intelligent linkage of any sensor data. - **RA4M2_TUYA_CBU_Project6**:RA4M2开发涂鸦模块CBU(6)----RA4M2驱动涂鸦CBU模组 - **CSDN Blog**:[https://coremaker.blog.csdn.net/article/details/148813218](https://coremaker.blog.csdn.net/article/details/148813218) - **Video**:[https://www.bilibili.com/video/BV1ETMBzrEVt](https://www.bilibili.com/video/BV1ETMBzrEVt) 本方案基于瑞萨 RA4M2 MCU 与涂鸦 CBU Wi-Fi & BLE 模组的无缝对接，旨在快速构建智能传感与控制终端。系统架构由 RA4M2 负责业务逻辑和外设驱动，CBU 模组提供网络接入与云端交互能力，两者通过标准串口通协议 (Tuya 通用协议) 完整实现产品功能上报与命令下发。 This solution is based on the seamless integration of the Renesas RA4M2 MCU with the Tuya CBU Wi-Fi & BLE module, aiming to quickly build intelligent sensing and control terminals.
