TLV Parameters getting changed while submitting

Hi,
I am using the below code to add TLV parameters during the submission.
Code: Select all
IList<SubmitSmResp> resp = _client.Submit(SMS.ForSubmit()
.From(srcAdr, srcTon, srcNpi)
.To(dstAdr, dstTon, dstNpi)
.Coding(coding)
.Text(tbSend.Text)
.ExpireIn(TimeSpan.FromDays(2))
.DeliveryReceipt()
.AddParameter(0x1400, "002760A9")
.AddParameter(0x1401, "0000146D")
.AddParameter(0x1402, "000002C3")
);
Our SMSC requires us to pass 3 TLV parameters as above. We are receiving updates from them saying that we are not passing the correct TLV values. After which we took the TCP dump using Wireshark & was able to find out that the values are getting changed. Check below for the screenshot. Please point out if I am doing anything wrong here? FYI: we have purchased the DLL version 1.1.20.0
Regards,
Hisham

Do you want to submit parameter value 002760A9 as byte array or as string?

I want to submit the TLV parameter values as String.

string "002760A9" in ASCII encoding is 0x3030323736304139
library didn't change the value. it has converted the string in byte array.

Our SMSC has sent us the pcap file which they had generated from their end, to show that the additional parameter value has to be in the same format.
Basically the requirement from SMSC is that we have to sent the TLV parameters as 8 bit Hexadecimal values.
0x1400 - "2580649" Its equivalent 8 Bit Hexa decimal value is "002760A9"
0x1401 - "5229" Its equivalent 8 Bit Hexa decimal value is "0000146D"
0x1402 - "707" Its equivalent 8 Bit Hexa decimal value is "000002C3"

You should use byte array:
Code: Select all
.AddParameter(0x1400, new byte[] {0x00,0x27,0x60,0xA9})
