Business story
As a high-tech company, SigmaWit is committed to manufacturing various smart wearables and smart home products and providing solutions for major manufacturers. A perfected and efficient IoT development platform helps shorten product development cycles, reduce R&D costs, and meet custom development requirements.
Why choose Tuya Smart
- Backed by Tuya's open IoT development platform and tens of thousands of smart hardware solutions, SigmaWit can quickly develop smart products. For example, according to the standard functions, the Bluetooth anti-lost finder can provide functions of one-tap search, search for mobile phones, one-tap navigation, disconnection alarm, and breakpoint memory.
- Tuya provides BK3431 chip based BLE SDK and demo, which can be directly compiled to generate stable and reliable firmware.
Solution
SigmaWit smart anti-lost finder adopts Tuya's free all-in-one app and is implemented through Tuya's BLE SDK and demo solution.
The complete BLE SDK and demo software architecture is as follows:
- App: the application layer, including DP parsing and service logic.
app_port: the isolation layer, used to isolate service logic and driver layer.tuya_ble_sdk: Tuya general pairing protocol.- Original chip SDK: the original underlying layer and driver layer.
component: commonly used third-party components.
Based on the demo, SigmaWit users can easily fine-tune and carry out a personalized design. Alternatively, through port adaptation, the demo can be quickly migrated to other chip platforms.
