E9500 - Bad Request (0x40)

[Christian Hilgers-2]

Hi,

from that command I expected to get more information from
the mobile:
syncml-obex-client  -b 00:0E:ED:AF:D6:E4 10 --identifier "PC Suite"
--dumpinfo --sync text/x-vcard Contacts
connection with device succeeded
Received an transport error: Bad Request (0x40)
Didnt receive the devinf though it was requested

The channel is OK:
sdptool search --bdaddr 00:0E:ED:AF:D6:E4 SYNCML
Searching for SYNCML on 00:0E:ED:AF:D6:E4 ...

Any ideas? What else can I test or provide?

I am using SVN code
build/bin/msynctool --version
This is msynctool version "0.36"
using OpenSync version "0.36"

Same mobile, different host:

Didn't we have a SVN tag in the opensync Version some time?

I get similar output when trying my Nokia 6230i.

Is syncml over bluetooth working for ANYONE with the latest SVN?

I discovered some bugs related to libsyncml after the changes which were
necessary for libsoup 2.4. Additionally the event handling in the syncml
plugin changed.

I don't think that this influences the OBEX client code. Additionally I
commited some changes to support Samsung mobiles. Perhaps these changes
in libsyncml/transports/obex_client.c damaged something.

Best regards

As Michael suggested, I tried to collect traces from a working
and a non-working revision. I am not able to find a working
version in SVN. I tried the following ones:

r403-410   do not compile

These revisions do compile, but show 0x43 forbidden
r409-r417
r419-r427

r418 fails with
/opt/opensync/libsyncml/libsyncml/sml_session.c:1598:E:smlSessionFlush: Assertion "error != NULL" failed
connection with device succeeded
Received an Alert for the DS Server at Calendar: Type: 201, Last , Next 20080409T124545Z
Just received a new session with ID 68
Received the DevInf
Session 68 reported final. flushing


current is: r427

r401 uses libsoup2.2
r403 uses libsoup2.4

I was not able to compile a version with libsoup2.2 till now.

My question:

How is able to run
/opt/opensync/build/bin/syncml-obex-client --identifier "PC Suite" -b $MAC $CHANNEL \
              --sync text/x-vcalendar Calendar --wbxml --dumpinfo
without the 0x43? Which svn revision?

Kind regards

Christian

Hmm.  I build libsyncml and opensync for Maemo from SVN (almost) every night,
using libsoup2.2-8.  Using my latest build (from 2008-04-06 00:00Z) I get the
same 0x43 error.

Does libsyncml require libsoup2.4?

No, definitely not.This library is only need for SyncML over HTTP. If
you can compile the syncml plugin and get trouble with OpenOBEX then the
core of the problem has nothing to do with the version of libsoup.

The introduction of libsoup 2.4 support only caused a major source code
update. Therefore I recommended to test a version before the libsoup 2.4
update if you are looking for a working revision.

Best regards

Ok, perhaps some systematic analysis is required ...

Did you sniffed the Bluetooth communication?
Do you know when the communication breaks exactly (last send and
received message)?
Does the plugin or the mobile create the error code?

Best regards

Hi,

if someone could trace the stuff with hcidump then please use options
like -a(--ascii) or -x(--hex) to make the stuff more humand readable.
this helps a lot with debugging.

Best regards

There is only one Event und only one contact in the mobile. I use this
device for opensync testing only.

During that time I run:
hcidump -w /tmp/osync_trace/hcidump.out
binary dump and decoded trace is attached.
run hcidump -r to process the binary

I am sorry, no idea; at least no error visible in the Mobile display.

Data was send in a seperate mail to Michael.

I got the same problem today and the solution is simple. You must remove
the build directory and run cmake again to create a clean build
environment. I got trouble with a libsoup 2.4 inclusion but I have no
libsoup 2.4 installed.

The names of the XML files are a little bit misleading but I found the
error. The mobile sends an alert 206 and we answer with status 200 and
alert 201 but if the server requests a slow-sync after the client
requests a normal two-way-sync then the server must answer with status 508.

The client answers with fresh alerts if it receives such confusing
signals and OpenSync is confused by the clients reaction. The only
question is how the error code was constructed and where ...

I think this is a bug in syncml_ds_server.c but I just started the
source code review ...

Many thanks for the dumps and the prepared XML files. This makes
analysing much easier.

Hi Christian,

I discovered that libsyncml calls a function _recv_alert from the syncml
plugin. This function was already replaced by _ds_server_recv_alert and
_ds_client_recv_alert to get better control over the alerts and flushing.

Do you know the SVN revision of your plugin?

Best regards

Michael

Hi Christian,

I introduced separate recv_alert callback functions in r3132. So your
used plugin must be from Thu Feb  7 12:11:06 2008 or older. Can you
approve this?

Best regards
