This topic describes how to use a device SDK for C-based application to connect a microcontroller (MCU) device on which a real-time operating system (RTOS) runs to IoT Platform.

Most electrical devices use one or more MCUs on which an RTOS runs. These electrical devices include industrial automation devices, data collection devices, real-time control devices, and home appliances. To connect these electrical devices to IoT Platform, use device SDK for C that is provided by IoT Platform.


Connect an MCU to a communication module and use AT commands for communication between the MCU and the communication module. Use device SDK for C to connect the communication module to IoT Platform and enable communication between each other.
