Hi Stipe,
Thanks a lot for the quick reply. Your answers were
enlightening for me. You may have understood that I'm a
WAP novice, just trying to make that thing work. I cannot risk
upgrading to 1.4.0 since I'm supposed to make a demonstration tomorrow.
Here are some answers:
1) What you say is correct for mime types, and it explains why I can't
download strange types of content, such as video in 3gp format. As I
was examining the logs, I've seen something which may be of help to
you, Sony Ericsson P800 sends Accept: image/* which causes Kannel to
give image/jpeg not supported warning. I also wonder, sometimes the
warning is "content type xxx not supported, deleting body" while
sometimes it's just "content type xxx not supported."
2) Ok, that solves my confusion about the maximum size of the content,
thanks very much. I've seen that the handset sends
X-WAP-Client-SDU-Size: 1400 which limits the data that can be sent.
3) Actually I don't see any timeouts in the logs, but sometimes the
handset seems to download the content successfully but it gives an
error "Unable to open". I do not know the exact cause of this problem,
I just thought that this may be related to long delays between the
communication. I will investigate this problem further.
Now, if you have time to answer, I have a couple of more questions. How
can I be sure that the content is received successfully and completely
by the handset by just examining the logs? If I don't see any error
messages, does it mean that everything is ok? And does
dispath_to_wdp(): psn = 10
mean that the gateway is sending something to the handset? If that's
so, how many of these messages should I see in the logs if I'm sending
a content of, say, 25K?
Sorry if I've asked too much :) And thanks again..
Regards,
Serkan

Hi
Serkan,
first of all, you should move towards 1.4.0 stable (1.4.1 stable is
coming up), since it's more reliable and contains a lot of bug fixes,
since 1.3.2 devel.

Hi all,
We are using Kannel 1.3.2 at a site for handset access to content
that's kept on a web server (Tomcat 4.1.29). The operating system is
RedHat Linux Enterprise 3 (kernel 2.4.21-15.ELsmp). The handset is sent
a wap service indication SMS containing the URL of the content to be
downloaded. We use GPRS as the bearer. During the download of contents,
we sometimes get the following errors:
WARNING: WSP: content-type <application/octet-stream> not
supported
--> Is there any way (a configuration file or something) that I can
make Kannel recognize the mime type application/octet-stream?
now, semantically this means: your HTTP server gives a HTTP response
with content-type <application/octet-stream), _but_ the phone has
not indicated (via Accept headers) that it accepts these media format.
Hence check if your HTTP server is configured the "right way" to
deliver the appropriate mime type. (Ie. your object is a midi, it
should obviously be not application/octet-stream, but audio/midi.)
WARNING: WSP: Entity at
http://192.168.210.201/icon_management/DownloadServlet/238/tYhthttxWY/Satisfaction.mid
too large (size 84705 B, limit 65535 B)
--> How does Kannel decide the limit? It gives different values for
different contents, such as 1400, 65535 or 10000 bytes. How can I
change these settings?
now, the device has indicated a specific client SDU size limit. So
obviously the device is not "capable" to handle a larger object. Can
you please check wapbox.log in debug log-level to review what the WSP
headers have been for this warning, and check if there is some kind of
indication that the client has "limited" it's own capabilities.
Also I believe that the operator's GPRS
network is slow, and there may be timeouts during the download process.
What's the default timeout while waiting for an acknowledgement from
the handset? Is it configurable?
can you point out for which timeouts this may be necessary? A snippet
from the wapbox.log would be perfect to document the need.
I would really be grateful if someone
could answer these questions as soon as possible.
as least with some delay, but hopefully "in time" ;)
