Hi,

If you are referring to decoding the UDH then you can do so using Wireshark.

thanks for your reply. I think I did not explain the question properly. Let me Explain with the help of example. UDH Header would be something like this (PDU Mode)
First Message:
05 00 03 21 02 01

where
05 = total header length
00= Element Identifier for Long Message Header
03= size of the header for Multipart message header
21= Unique Identifier
02= total number of parts
01= Part number of message

For second Message
05 00 03 21 02 02

Now If I want to edit this information and bring the packets information into continous unlimited flow
how can I do that.

thanks.
 



Now if I want to increas
