篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了STM32F103 GU906B模块GPRS短信收发拨号等功能的实现相关的知识,希望对你有一定的参考价值。
这个程序搞了我很久,尤其是对如何提高响应速度上,程序流程很简单,大概就是:
发送AT指令->等待模块响应->一旦响应了,立即返回,并处理掉。
这个程序不一定只能用在GU906上,程序框架在任何GPRS模块上都能用,只要修改相应的AT指令,按照对应模块的AT指令流程,做下流程上的修改,就没啥问题,框架很简单,不像某宝上店家的那些代码一样,那些代码反正我是看的头晕,程序接口我都留着,只要按照相应的流程调用接口就好。
下面是模块的代码gu906.c文件
