这里有用过GSM AT 指令的吗？我有一些问题想请教

[lingfeng42]

发送短信，我采用的是AT+CMGF=1（为文本方式）。在接收的时候用想用CMGL可是列不出数据来，如果用CMGR就可以。如果AT+CMGF=0 CMGL可以列出数据来。现在有一个问题，如果采用CMGR，，在程序关闭的时候来的短信不可以显示，因为不知道它存储在什么位置，请问各位有什么好的办法吗？有没有什么相关的AT指令那，，，对了，在用CMGR之前，，读串口，看是否有+CMTI:返回。。。

谢谢

如果你的MODULE是符合GSM 0705 的话，应该有CPMS用于指定短信保存的位置，你查一下。格式应该是这样

CString code("AT+CPMS=\"");

code += rmem; //读存储
code += "\",\"";
code += wmem; //写存储
code += "\"\r";

还有就是在你程序停掉以后其实MODULE还带电运行，所以有短信过来它还是会接收的，只要你这是保存的STORE就可以了。
另外在初始化设备的时候设置CNMI，格式应该是这样
CString tmp1("AT+CNMI="), code("");
char tmp2[50];

memset(tmp2, 0, 50);
sprintf(tmp2, "%s%d,%d,%d,%d,%d\r", tmp1, mode, mt, bm, ds, bfr);
code = tmp2;

参数值用CNMI(2,1,0,0,0);

这样就可以保证如果接收的信息没有及时读取的话可以保存到我们制定的STORAGE中去

我记得你前几天好像问过短信的事，你是不是在作短信的项目呢。我感觉你用的是WAVECOM的MODULE，其实网上有很多现成的收发短信的例程，你应该去看看

这是wavecomQ2406a得关于短信得AT指令，希望帮你有用。

我这里也有标准得GSM7.07得相关指令，西门子的也有，wavecom公司的CDMA的也有。
