With the rapid development of cloud computing and big data technology in recent years, the smart home industry has also become popular and has received widespread attention. The popularity of the market and the popularity of consumer concepts continue to drive the industry's progress. Smart door locks are becoming more and more accepted as an important part of the security category in smart homes. The current door lock market is at an early stage of rapid development, not only for the transformation of traditional door lock manufacturers, but also for the influx of Internet giants and the joining of startups. The technology solution options that company can adopt is plenty, but quality is uneven, the good and bad ones are intermingled. In view of the lack of technical development of traditional door lock manufacturers for electronic products, AIT group developed smart lock Turnkey Solution based on the Qualcomm QCA4024.QCA4024 is Qualcomm designed specifically for IoT to support BLE, ZigBee dual mode SoC. Please refer to Qualcomm official website for the detailed performance of QCA4024.
We provides complete product solutions, including software and hardware design materials, APP. This is a complete design prototype for demonstration, and all the design documents, codes are completely open to contracted customers.
The latest SDK is currently based on Qualcomm's qca4020.or_.3.0 version of QSDK. The SDK has full functionality and runs through the underlying and application layers in the form of middleware. Support for modules such as motors, fingerprints, voice, touch, display, etc., and reserve support for other modules. The network communication integrating Bluetooth and WiFi and ZigBee realizes the interconnection and intercommunication between the cloud and the mobile terminal, and the provided APP can realize the locking and unlocking through the cloud and the mobile terminal, the history record query and the OTA function. The SDK combines the scheme in multiple forms of connection, BLE; ZigBee; BLE+ZigBee.

The overall software architecture is as shown
Code hierarchy
The code directory is as follows
Development environment can be built under Windows，Support Windows 7、Windows 10。Required development tools:
- GNU embedded toolchain
- Python
- Serial debugging tool ( Such as：putty、13.1、Tera Term)
The compilation process is shown in the figure
The burning upgrade process is shown in the figure.
The program provides APP for custom development. Both Android and iOS versions are supported. The mainstream functions in the market are integrated, and with source code level support, reducing the difficulty of secondary development of customers.
The main function interface of the APP is as follows:
Main interface
Smart lock connection interface
Temporary password setting interface
Setting new Manager interface
