简要介绍了GPRS模块的应用情况和特性,并针对这些应用特性,利用有限状态机和消息机制的原理分别设计了应用的方案,较好地解决了由于应答延迟而导致的模块与MCU之间存在的交互问题,类似的方法也可以应用于其他类似的通信和控制的应用场合。
The application and characteristics of GPRS module are briefly introduced. According to the characteristics of these applications, the schemes of the finite state machine and the message mechanism are respectively designed and applied to solve the problem that the delay between modules and MCU A similar approach can also be applied to other similar communications and control applications.
