安信可A6模块短信模式的配置

前段时间搞了下这个，配置的时候碰到很多问题。
最后上电初始化时是这样配置的

AT                          //第一条为无效指令，A6模块根据这次数据传输调整波特率AT+GMGD=1,4                 //删除存储的所有短信AT+CSMS=0,1,1,1             //选择短消息服务AT+CNMI=2,2,0,1,1           //配置短信接收模式AT+CMGF=1                   //设置短信格式为textAT+CSCS="GSM"               //设置短信编码用GSMAT+CPMS="SM","SM","SM"      //选择短消息内存为SM卡

附上模块程序（STM32F103C8T6）

虽然现在能成功接收短信了，但如果之后新的模块的SDK发生变化那发送的指令可能也会发生变化。
