SDK Architecture

Architecture description

Layer	Description
Application	Applications built on top of the Bluetooth SDK.
MessageorCallBack	The SDK sends data or events to the mobile app using messages or the registered callbacks.
Main Process Function	Serving as the main engine of the SDK. This function is called by `Application`. If your chip runs an operating system (OS), the SDK will automatically create a task by using the OS API from the `port` layer to run `Mainprocessfunction`. If your chip does not run an OS, this function is called in a loop.
Tuya Bluetooth LE SDK API	The SDK provides APIs for managing Bluetooth communication. If your chip runs an OS, API calls are made based on asynchronous message-based communication, and the result of an operation is returned to the device application through a message or a callback. If your chip does not run an OS, the return value of an API call is the result of an operation.
SDK Config	The configurable SDK allows you to tailor functionality by editing the macro in the `config` file. For example, you can configure a general pairing mode for various network protocols, and the considerations can be Bluetooth LE devices, Elliptic Curve Diffie-Hellman (ECDH) encryption scheme, OS, and more.
Tuya Bluetooth LE SDK	Tuya’s Bluetooth communication protocol is included in the SDK to provide the required interfaces for Bluetooth-based applications.
Port	The abstract hardware interfaces that you need to port to your chip platform.
Platform	The chip platform. The chip and protocol stack is maintained by the chip producer.
