Overview
Wi-Fi & Bluetooth Matter Lite Device Development Kit is built on top of the TuyaOS and designed for developing smart Wi-Fi and Bluetooth LE combo products. It supports the Matter standard and provides related functions. You do not need to take care of feature implementation for different Wi-Fi and Bluetooth combo chip platforms. Just working on the standard APIs, you can make them IoT-enabled.
Features
Wi-Fi & Bluetooth Matter Lite Device Development Kit is provided to help you implement Matter-enabled devices quickly and efficiently. This kit does not support TuyaOS capabilities.
Resource requirements
Wi-Fi & Bluetooth Matter Lite Device Development Kit requires 900 KB ROM and 150 KB RAM.
Capability map
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. |
Third-party ecosystem
| Capability |
Description |
| Matter |
The full features of Matter protocol enable your device to be Matter-compatible and integrated into the Matter ecosystem. |
Basic services
| Capability |
Description |
| Secure storage |
Encrypted key-value store as well as file-based data storage in plain text. |
| Health checks |
Regularly check the device memory, wireless signal, and task status. You can customize the metrics. |
| 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 queue |
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. |
