Overview

TuyaOS is designed with a modular approach, with capabilities covering basic services, security, networking middleware, and various IoT services. Built on top of TuyaOS capabilities, TuyaOS NB-IoT Cellular Development Framework is a set of SDKs used to build NB-IoT products for different specifications and scenarios. Unified APIs and a variety of components allow you to focus on building applications with a consistent development experience, without taking care of specific implementations.

Capability list

Device management

Capability	Description
Initialization	After a device is powered on and started, it calls a range of APIs to initialize the hardware environment, TuyaOS software, and applications. On application initialization, you need to provide callback functions as needed to handle internal events including status changes, device controls, and firmware updates.
Reset	A device is restored to the settings that the device had before it was paired and activated. Device reset can be triggered by hardware operation or mobile app operation. In terms of device status after a reset, there are two types of reset: normal reset (device unbound) and factory reset (device unbound with data erased).
Authorization	Authorization is the process of writing the device ID assigned by Tuya to the non-volatile memory on the device for the purpose of authentication. You can perform authorization through code or a tool. The former is for debugging purposes, and the latter is for mass production.

Basic services

Capability	Description
Secure storage	Encrypted key-value store as well as file-based data storage in plain text.
Logging service	Local logs that record device operations. Exceptions can be recorded, sorted, and reported to the cloud.
Event service	Event subscription and publishing. This allows you to monitor and handle events as needed.
Time service (time zone and daylight saving time (DST))	Time management and maintenance. UTC time and local time are supported. Local time is determined by UTC time, time zone, and DST.
Timer	Software timers.
Job queue	Job queues used to process asynchronous low-priority tasks on which blocking might occur.
Connection management	Device connection management, such as Wi-Fi, Ethernet, and Bluetooth. It is used to maintain the direct connection between devices and the network.
Thread management	Managing threads.
Discrete mechanism	The discrete mechanism is used to reduce network congestion when you onboard a large number of devices at the same time.

Device driver

Peripheral driver

Capability	Description
GPIO	GPIO driver
ADC	ADC driver
PWM	PWM driver
I2C	I2C driver
UART	UART driver
SPI	SPI driver
RI	Ring indication (RI) signal driver

Power management

Capability	Description
PSM	Power saving mode
eDRX mode	Extended discontinuous reception
DRX	Discontinuous reception

Scheduled task

Capability	Description
Local schedule	The scheduled task is downloaded to the device with a timer created accordingly. The device runs the task after the timer expires.

Update service

Capability	Description
Silent update	The device checks for and installs firmware updates automatically.
Update notification/forced update	The mobile app notifies the device of available firmware updates.
Subordinate firmware update	Update firmware and files on the device.

File download

Capability	Description
File download	The file download service for certain products and features, such as ephemeris data and fingerprint files.

Device security

Capability	Description
Security system (security level and capability)	Device authentication, secure storage, secure communication, and privacy and data compliance.

Network

Capability	Description
LwM2M	LwM2M library for China Telecom
OneNET	OneNET library for China Mobile
