Adding a UDH?

Post by AG70 » Wed May 22, 2013 4:25 pm

Hello,

From client code example at SubmitBatchMessages method my modified code look like this:

Code: Select all

for (int i = 0; i < count; i++)
            {
                //05 00 03 AB 02 02
                byte[] aaa = new byte[6];
                aaa[0] = 0x05;
                aaa[1] = 0x00;
                aaa[2] = 0x03;
                aaa[3] = 0xAB;
                aaa[4] = 0x02;
                aaa[5] = 0x02;
                
                UserDataHeader udh = new UserDataHeader();
                udh.Data = aaa;

                ISubmitSmBuilder builder = SMS.ForSubmit()
                    .Text(text)
                    .From(srcAdr, srcTon, srcNpi)
                    .To(dstAdr, dstTon, dstNpi)
                    .Coding(coding)
                    .Set(delegate(SubmitSm sm) { sm.Sequence = 12; })
                    .Set(delegate(SubmitSm sm) { sm.UserDataPdu.Headers.Add(udh); })
                    ;

                switch (mode)
                {
                    case SubmitMode.Payload:
                        builder.MessageInPayload();
                        break;
                    case SubmitMode.ShortMessageWithSAR:
                        builder.ConcatenationInSAR();
                        break;
                }
                _client.SubmitAsync(builder);

                Application.DoEvents();
            }
Problem is that when submitting to SMPP Server the UDH should arrive as 050003AB0202 but instead it arrives with leading bytes as marked in red 080006050003AB0202
How to delete leading three bytes?

* I know that Inetlab.SMPP can automatically concatenated messages but my situation is a different and I must submit each part of the concatenated with UDH and Text.

Thanks in advanced for any help,
Asaf
Kind Regards,
Asaf
