使用AT命令接收短信 [英] Received SMS using AT Command

问题描述

string recievedData = ExecCommand(port, "AT", 300, "No phone connected at ");
recievedData = ExecCommand(port, "AT+CMGF=1", 300, "Failed to set message format.");
String command = "AT+CPMS?";
recievedData = ExecCommand(port, command, 1000, "Failed to count SMS message");
int uReceivedDataLength = recievedData.Length;

#endregion
//We received uReceivedDataLength 34 that false the condition
#region If command is executed successfully
if ((recievedData.Length >= 45) && (recievedData.StartsWith("AT+CPMS?")))
{

    #region Parsing SMS
    string[] strSplit = recievedData.Split(',');
    string strMessageStorageArea1 = strSplit[0];     //SM
    string strMessageExist1 = strSplit[1];           //Msgs exist in SM
    #endregion

    #region Count Total Number of SMS In SIM
    CountTotalMessages = Convert.ToInt32(strMessageExist1);
    #endregion

}

最后错误显示SIM中没有消息

At last error show "There is no message in SIM"

推荐答案

+ CPMS？是AT命令，用于获取有关设备支持哪些消息存储的信息，而不是实际获取消息。

+ CMGL =REC UNREAD是用于从消息存储读取未读消息的AT命令，使用ALL获取所有消息。

您将只检索消息从您使用+ CPMS =...命令选择的消息存储库中，+ CPMS =MT从SIM卡和手机存储中选择消息。

+CPMS? is the AT command to get information about which message stores are supported by the device, not to actually get the messages.
+CMGL="REC UNREAD" is the AT command to read unread messages from the message store, use "ALL" to get all messages.
You will only retrieve messages from the message store you have selected using a +CPMS="..." command, where +CPMS="MT" selects messages from both sim and phone storage.
