使用短信猫收发短信,原理是通过串口通信发送AT指令.当你发送中文短信时,你会又喜悦又困惑,短信确实收到了,但是是乱码的.本文介绍如何正确发送中文短信.

AT

AT\r\r\nOK\r\n

设置modem为SMS text mode

AT+CMGF=1<ENTER>

AT+CMGF=1\r\r\r\nOK\r\n

查询当前参数

AT+CSMP?<ENTER>

AT+CSMP?\r\r\r\n+CSMP:1,167,0,0\r\n\r\nOK\r\n

displays the codepages supported by the modem

AT+CSCS=?

AT+CSCS=?\r\r\n+CSCS:(\"GSM\",\"PCCP437\",\"CUSTOM\",\"HEX\")\r\n\r\nOK\r\n

设置modem为hex mode

AT+CSCS="HEX"<ENTER>

AT+CSCS=\"HEX\"\r\r\r\nOK\r\n

specify the correct DCS (Data Coding Scheme) forUnicode messages, which is 0x08

AT+CSMP=1,167,0,8<ENTER>

AT+CSMP=1,167,0,8\r\r\r\nOK\r\n

设置sms发送的手机号码

AT+CMGS="+31638740161"<ENTER>

"AT+CMGS=\"+31638740161\"\r\r\r\n>"

以unicode编码发送SMS

"\r\n>"

测试

C# unicode编码方法

       public staticstring ConvertToUTF(string input_text)

        {

            string _out = String.Empty;

            char[] _chars =input_text.ToCharArray();

            foreach (char c in _chars)

            {

                _out +=((Int16)c).ToString("X4");

            }

            return _out;

        }
