I see that support sucks here. Most of questions have no answers and I wonder providers acting same to person who bought this product.

Dear araxno,

SmppClient Demo has example method where concatenated messages are processed

Code: Select all

private void client_evDeliverSm(object sender, DeliverSm data)
		{
            if (data.SegmentNumber > 0)
            {

                AddMessageSegmentToCollector(data);

                string messageText = SmppClient.GetMessageText(data.UserDataPdu.ShortMessage, data.DataCoding);

                AddToLog("DeliverSm part received : "
                    + " Sequence : " + data.Sequence.ToString()
                    + " SourceAddr : " + data.SourceAddr
                    + " Segments ( Number: " + data.SegmentNumber.ToString()
                    + ", Total : " + data.TotalSegments.ToString()
                    + ", Reference : " + data.MessageReferenceNumber.ToString()
                    + " ) Coding : " + data.DataCoding.ToString()
                    + " MessageText : " + messageText);


                if (IsLastSegment(data))
                {

                    string fullMessage = RetrieveFullMessage(data);

                    AddToLog("Full message: " + fullMessage);
                }

            }
            else
            {
                string messageText = SmppClient.GetMessageText(data.UserDataPdu.ShortMessage, data.DataCoding);

                AddToLog("DeliverSm received : "
                    + " Sequence : " + data.Sequence.ToString()
                    + " SourceAddr : " + data.SourceAddr
                    + " Coding : " + data.DataCoding.ToString()
                    + " MessageText : " + messageText);

            }
		}

But some SMSC sends incorrect DeliverSm packets. In this case please post here received data bytes array for analize.
