Hi J�rg,

tokenization of multipart document is defined in wsp-230, chapter
8.5.

Hi Ken,
thanks for your input. Yes, I suspected the content type myself,
so I will do some further experimenting in this area. I was not aware 
that
the content type is actually limited to 
application/vnd.wap.multipart.mixed.
The T-Mobile MMSC here in Germany happily accepts whatever I send 
(tested
with text/plain, image/jpeg, image/gif) and the T610 displays all of 
this.

To answer your question: This is a trace from my MMS client. I choose
the Ericsson User-Agent header because this is what I used to test
the SIM cards to make sure they are actually MMS enabled.
Kind regards

Hi,

Just quickly scanning your pdu, I noticed that your content-type is 
0x83
(text/plain). This should be 0xA3(application/vnd.wap.multipart.mixed)
followed by 0x01(representing the number of contents in your multipart 
mixed
mime message.)

See 7.4.1 of the mms conformance doc for more details. You can only 
have
application/vnd.wap.multipart.mixed or
application/vnd.wap.multipart.related(for smil)

Then for each mime part your start out with:
-----
<length of content-type> eg:0x01
<length of data>
0x83 -- content-type:text/plain
{data....}
-----
Something like that.
Just curious, is this what the T610 spits out, or is this your own mms
client?
Cheers,
Ken

Hi List,
I'm trying to get a MMS client to work. Unfortunately
with only minor success so far.
Attached is a tcpdump of the communication between the
MMS WAP gateway (from the German network operator E-Plus)
and my MMS client. You can view it with ethereal (both, under
Linux and Windows).
Any ideas what I'm doing wrong?
Thanks in advance
