Hi Vinicius
I am trying to use the obex-client for ftp recent days.
I found that after I call the CreateSession method. The data return by introspect method is not updated in the root path.
Say, I can only use dbus-send --print-reply --dest=org.openobex.client /org/openobex/session0 org.freedesktop.DBus.Introspectable.Introspect to find out the ftp method.
But dbus-send --print-reply --dest=org.openobex.client / org.freedesktop.DBus.Introspectable.Introspect will not show that there are a /org/openobex node under this path. So it might not be easy for a user to know what kind of interfaces is provided for the whole org.openobex.client service. Since they will not know what's the right node path name.
I guess we can add a node, or child field, and a parent field in the generic_data structure, and update these information during the interface register operation, so that the introspect method can show the child node under a certain path?
Best Regards,
Raymond Liu

Hi Vinicius, johan, holtmann
=09
In the current obexd, gw_obex_get function do not handle the application p=
arameter for PBAP function head. I heard that someone have a patch for this=
, but I can not find it on the list's archive. Can you kindly share me the =
information?
And if there are no such patch I plan to write another pce_gw_obex_get fun=
ction for this purpose, for I think add too much input parameters in the gw=
_obex_get function might not be a good choice. How do you think about it?

Really strange, Thanks for johan's help, I notice that bluez's introspect method work for the child node too, it can show the adapter's interface correctly. And the gdbus dir of bluez and obexd is almost the same! I have double check for several times, then why one is working while another don't?

Hi holtmann, johan
I am writing PBAP client code for obex-client. While I found that the regi=
ster_record function which adds record to SDP is in the manager.c file. Whi=
le for FTP and OPP, they don't need a SDP record in Client side. So it's ok=
. But for PBAP Client, the spec requires the PBAP client to register its re=
cord PCE in SDP.
So, Should we move this function out to some library? Or I just copy the c=
ode into client side?

Hi, I just try out /org/freedesktop/Hal, it also employ a set of child nodes under "/" path, however, d-feet can read them out correctly, So I guess, for obexd, the reason it do not work is because we do not provide the child node info in the "/"'s introspect method. Not the bad of d-feet tool

OK, I see. However, what if the other one who not want to create the session by themselves. They just want to know is there already a session exist and can be used through Dbus interface? They might probably not read the client-api doc 8 )

Yes, I try it out. It a good tool, Thanks!
However, as you said, it will not recognize the node under "/", I am wondering, is that because we do not provide the introspect info for child node , or just the bad of this tool? So user who use d-feet still could not find our secret interface :)

OK, I just think that to support child node info in introspect from the root path might be more friend to the end user. If you think it's ok, it is :)

Got it! Thanks.

Or taking a look at the documentation at doc/client-api.txt ;-)

I find d-feet very useful when I am exploring some app DBus interface.
Just be aware
that d-feet doesn't like very much the "/" root path, you might find
it useful to change
the root path (client/main.c:41) to something other than "/"
("/client" for example).
Using this trick I was able to verify that the
"/org/openobex/session0" node is being added to
the bus, it is just not being added as a child of the "/" node, but in
parallel to it.

I don't really see this as a bug.
