使用pdu格式通过gsm调制解调器发送波斯短信 [英] use pdu format for send persian sms by gsm modem

问题描述

请帮助我

if (!comPort.IsOpen)
               comPort.Open();
           comPort.DiscardInBuffer();
           comPort.DiscardOutBuffer();

atCommandStr = "AT";
           comPort.WriteLine(atCommandStr + (char)13);
           messageTXT.Text = comPort.ReadExisting();
            //baraye moshakas kardan halate PDU
           atCommandStr = "AT+CMGF=0";
           comPort.WriteLine(atCommandStr + (char)13);
           messageTXT.Text = comPort.ReadExisting();
           atCommandStr = "AT+CMGS=20";
           comPort.WriteLine(atCommandStr + (char)13);
           messageTXT.Text = comPort.ReadExisting();

string path;
           //path = "0681398647575611000B819083660786F00008FF06062A0633062A" + Char.ConvertFromUtf32(26);
           path = "0681398647575611000B819083660786F00008FF06062A0633062A" + Char.ConvertFromUtf32(26);
           comPort.WriteLine(path + (char)13);
           //read immediately response
           messageTXT.Text = comPort.ReadExisting();
           comPort.Close();

运行此代码，但不发送短信
问题出在哪里?

run this code but do not send sms
where is problem ?

推荐答案

也许您在PDU消息中缺少时间戳.

0681398647575611000B819083660786F00008FF06062A0633062A转换为:


SMSC#9368747565
发件人:09386670680
TP_PID:00
TP_DCS:08
TP_DCS-popis:未压缩的文本
类别:"0"
字母:UCS2(16)bit
تست
长度:3

Perhaps you are missing a timestamp in the PDU message.

0681398647575611000B819083660786F00008FF06062A0633062A is converted to:


SMSC#9368747565
Sender:09386670680
TP_PID:00
TP_DCS:08
TP_DCS-popis:Uncompressed Text
class: "0"
Alphabet:UCS2(16)bit
تست
Length:3

而不是:

Instead of:

path = "0681398647575611000B819083660786F00008FF06062A0633062A" + Char.ConvertFromUtf32(26);
comPort.WriteLine(path + (char)13);

做:

do:

path = "0681398647575611000B819083660786F00008FF06062A0633062A";
char eof = Convert.ToChar( 26 );
comPort.Write( path + eof );

最好的问候


编辑.
我刚刚检查了您的pdu长度.

best regards


edit.
i just checked your pdu length.

atCommandStr = "AT+CMGS=20";

应该是

should be

atCommandStr = "AT+CMGS=26";

一般而言:
AT + CMGS =(pduString.Length/2)-1

in general:
AT+CMGS = (pduString.Length / 2) - 1

感谢所有
我发现我的问题
当Pdu中的解码必须发送Sumber Be Whitout 0
例如

发送至:935421542
讯息:دلتاسافت

Pdu代码:00110009A139451245F20008AA12062F0644062A06270020063306270641062A

解码后:

Thanks From All
I Find My Problem
When Decode In Pdu Must Send Sumber Be Whitout 0
For Example

Send To:935421542
Message:دلتا سافت

Pdu Code:00110009A139451245F20008AA12062F0644062A06270020063306270641062A

After Decode:

Service center number:
Service center time stamp: 01/01/0001 12:00:00 ق.ظ
Message reference #: 0
Direction: Submited
Phone number: 935421542
Status report indication: False
Message:
دلتا سافت

此Pdu格式为真

This Pdu Format Is True
