What is TuyaOS?

Last Updated on : 2022-06-13 03:46:42download

Built on top of the RTOS, Linux, and Non-OS, TuyaOS is a distributed and platform-agnostic IoT operating system.

Overview

With a standard kernel at the core, TuyaOS is designed to tackle the heterogeneity of platforms, systems, and protocols in order to enable quick and reliable integration, interconnection, and interoperability.

The tiered and plug-and-play architecture design allows you to quickly tailor a solution based on your hardware resources hence reducing the cost of development with high cost performance. The efficient remote procedure call (RPC) mechanism and proprietary data point (DP) protocols make communication across protocols possible and easy.

Step 4: Flash firmware and authorize chip

Flash the device with the firmware and Tuya’s license to connect the device to the cloud.

Tuya provides two options for flashing to meet different requirements of development methods.

  • Flashing by Tuya

    For the no-code and MCU SDK development methods, you will get modules that are flashed with firmware and license by Tuya. This way, you can use the module directly.

  • Flashing on your side

    For other development methods, you need to flash the firmware and license and verify the code by yourself. The flashing methods vary depending on the chip platform. For more information, see the documentation in the Flash And Authorize catalog.

Step 5: Test functions

You can check the device logs on the Tuya IoT Development Platform for troubleshooting. For more information, see Log query.

(Optional) Step 6: OTA updates

The Tuya IoT Development Platform provides multiple update methods. You can upload the required firmware updates and complete the deployment settings. Then, an OTA update will be deployed to your users. For more information, see Update Firmware.
