RT-Thread was born in 2006, it is an open source, neutral, and community-based real-time operating system (RTOS).
RT-Thread is mainly written in C language, easy to understand and easy to port(can be quickly port to a wide range of mainstream MCUs and module chips). It applies object-oriented programming methods to real-time system design, making the code elegant, structured, modular, and very tailorable.
RT-Thread has Standard version and Nano version. For resource-constrained microcontroller (MCU) systems, the Nano version that requires only 3KB Flash and 1.2KB RAM memory resources can be tailored with easy-to-use tools. For resource-rich IoT devices, RT-Thread can use the on-line software package management tool, together with system configuration tools, to achieve intuitive and rapid modular cutting, seamlessly import rich software packages; thus, achieving complex functions like Android's graphical interface and touch sliding effects, smart voice interaction effects, and so on.
The REST Interface gives you access to your RT Database. The complete communication is encapsulated in the HTTP protocol. The interface should be accessible in your installation.
Though you may see references to older 3.x releases of RT below, Best Practice indicates that the REST stuff has not changed in any significant way in 4.x as of, at least, 1/2012.
