Specifically, in one embodiment of the present invention, the software of the communication module is evolved from the original 2-layer structure (platform layer and AT layer) to a 4-layer structure. When the code of AT instructions is developed on different chip platforms, it only needs to adapt to the abstract interface layer. Both the AT service layer and the business layer can be directly reused.

The communication module of the embodiment of the present invention decouples the business-side code from the chip platform through core ideas such as software layering and dependency inversion, thereby improving the cohesion of the business-side code. It can realize good cross-platform features of AT command processing. When developing new communication modules, developers only need to implement board-level adaptation of abstract interfaces, and the upper-layer code can be directly reused.

In the Asyn Socket interface, Asyn DNS interface and Asyn SSL interface, asynchronous sockets and abstract interfaces are unified to implement sockets and encryption and decryption asynchronous event-driven models, as well as asynchronous domain name resolution; at the same time, these abstract interfaces provide application layer data services Standardized asynchronous processing entrances and exits to avoid issues such as thread resource consumption and increased power consumption caused by blocking methods in multi-service situations;

By abstracting out hardware interfaces and general interfaces, the platform dependencies of applications are completely eliminated, such as serial port input and output, file system access, etc.

The business layer code that meets the strategy can be replaced at any time, reducing the coupling between the AT service layer and the business layer, and realizing AT layer APP and business layer functions are used at the same time.

In one embodiment of the present invention, the business-side code (AT command code of the business layer) relies on the basic abstract interface and can be placed on the GitLab server for unified iterative maintenance using the package management mode. When developing communication module software, only the board-level adaptation of the abstract interface layer needs to be completed. After determining the target parameter verification interface, obtain the AT business side code from the GitLab warehouse as needed based on the target parameter verification interface.
