Re: [Bluez-users] bluetooth-applet and gnome-vfs-obexftp

First let me say, Marcel, that I didn't mean any personal offense to
you.  Please don't feel under-appreciated for all the good work you're
putting into bluez-gnome.  I'm glad to get a response from you.

If you don't agree with anything else I say please at least consider
this:  The applet should not offer to browse an obex-ftp device unless
gnome-vfs-obexftp is installed.  It probably needs to be a run-time
dependency so that distros that offer vfs-obexftp but not by default
can expect the applet to work properly.

I'm trying to help Ubuntu's next release not have a prominent new
feature that doesn't work out of the box.  They aren't including
gnome-vfs-obexftp by default in gutsy (maybe they'll change their
mind?) so it looks a bit ugly when you get an error message saying you
can't browse the thing bluetooth-applet says you can browse.

Don't get me wrong - gnome-vfs-obexftp is awesome, but
bluetooth-applet is the wrong entry point for it.  The applet should
allow you to see what devices are around you and allow you to initiate
a bonding with them but the assumption that you want to browse OBEX is
bad.

it is exactly the right entry point. You might wanna compare how MacOS X
handles it. The actual bonding will be done automatically. You are the
client and so we can rely on the actual FTP server to ask for a bonding
and not wasting time to try to pair a public FTP repository that has no
key anyway.

Good point that the bonding should be / is done automatically.  I
still think the applet is the wrong place for OBEX though - mostly
because I think nautilus /is/ the right place for it.

MacOS X does it the wrong way IMHO.  They treat their bluetooth ftp
like a GUI ftp client rather than just another location in the Finder.
 Gnome is doing it better by having a vfs module to support it, and
Maemo (Nokia N800 / 770, for which gnome-vfs-obexftp was written)
takes it one step further in the right direction by showing you your
device in the file manager if it's connected.  It does this in much
the way I proposed here.  (Yes, I know that this isn't the right place
to propose that change.  Sorry about that.)

Another problem with this approach is that it creates a dependency on
gnome-vfs-obexftp and assumes that it's present.  If it's desirable to
have the applet launch other programs it should support more than
obex:// and there should be some generic mechanism for programs to
plug themselves in as handling a given service.  It should be possible
some day to get a bluetooth mouse working from the GUI, or a bluetooth
headset, for example.

It only supports Bluetooth FTP and is not meant to support everything.
So I have no idea what you are talking about. Use the preferences dialog
or the upcoming wizard to connect other type of Bluetooth devices.

I have discussed this with James Henstridge a little and while he's
not opposed to adding support for other transports to
gnome-vfs-obexftp he would agree that the other transports are a lower
priority.  My main concern is that we'll hard-code obex = bluetooth
everywhere so that if someone extends gnome-vfs-obexftp to support USB
and other transports there won't be any place for it in gnome anyway.

I'd also love to see Edd Dumbill's gnome-obex-server and
gnome-obex-send support other transports, particularly IrDA.  In a
perfect world it would also advertise itself via Avahi and support
file push over TCP.

Of course there needs to be better integration of gnome-vfs-obexftp,
but that integration should be in nautilus where everything else
vfs-related is found.  A bluetooth link under computer:/// when an
adapter is present would be sufficient (though I wish we'd treat OBEX
more generically as well - it's got 3 or 4 transports besides
bluetooth).

We know that OBEX supports more than the Bluetooth transport, but which
of these transports actually have devices that support FTP like
transactions. Most of them only allow to push or pull a file. However
feel free to fix gnome-vfs-obexftp to make this work.

Quite a lot of devices support OBEX FTP over USB - and USB is a lot
faster and some more reliable than BT.  Probably far fewer devices
that use OBEX over IrDA support anything but PUSH.  And there may in
fact be no services or devices that do OBEX FTP over TCP, but the
underlying library (openobex) and the commandline client (obexftp)
support all of these.

If you wanna have the Bluetooth adapters (yes, plural. We can have more
than one) under computer:/// then go ahead a send patches upstream. I
personally don't care and I am not responsible for that part of
software.

Sorry, I shouldn't have mentioned what I thought could be done in
other projects, that really has nothing to do with you.

As usual with these kind of things, I am not the UI expert and if you
wanna have fixed or changed something, you better send in a patch. We
always welcome new development blood.

I'm not a UI expert either.  I was just disappointed that the first
gnome (non-cli) interface for connecting to a bluetooth device was
really an interface to connect with an OBEX FTP device on a bluetooth
transport.  I plainly admit that I had false assumptions about what
that feature was supposed to be and my disappointment is due primarily
to those false assumptions.  It sounds like the preferences dialog and
the druid will cover my needs nicely.

Also thank you for being welcoming to new developers.  I need to dive
into one of the projects I am interested in.  I appreciate the idea
that I'd be welcomed if I chose bluez-gnome.

May I ask, by the way, if bluez-users was the wrong place to bring this up?
