Hi,
I am the maintainer of ofono-qt library, which provides Qt bindings to
ofono services and licensed under LGPL 2.1:
http://meego.gitorious.org/meego-cellular/ofono-qt
I would like to get in touch with everyone who is using it, or perhaps
would like to use it, and find out if there is anything incomplete,
missing or possible to improve there. Let me know please.
Also, if you know an easy way to find out what is dependent on this
library in Meego, that would be great too.

Hi Alexander,
I started to use ofono-qt recently. And first of all, I would like to
say, that it does offer a very nice DBUS abstraction.
I'm not a user of the voice call interfaces, just the modem, sim,
network and connman (mobile broadband use case).
I'm actually integrating ofono(-qt) (and other stuff) into PTXdist
(Reproducable Embedded Linux Systems) [1]
1. Releases.
I've found 2 places for the tarballs:
- git:
path:
http://meego.gitorious.org/meego-cellular/ofono-qt/archive-tarball/<ve...
filename: meego-cellular-ofono-qt-<version>.tar.gz
(which uncompress into a folder named "meego-cellular-ofono-qt"
- meego: http://api.meego.com/public/source/Trunk/libofono-qt/
name of the archives: ofono-qt-<version>
which uncompress nicely into a folder named ofono-qt-<version>,
unfortunately, this is not a repository, as it contains only the version
used by meego something.
So, to make it clear and simple, is there any official repository for
ofono-qt?
2. "slotification" of various member functions:
member functions like OfonoModem.setPowered(bool powered) could be
declared slots, so that it can be connected to signals of same signature
like QCheckBox.toggled(bool)
3. More convenient function members (I'm getting picky, I know)
example for OfonoModem:
- existing: setPowered(bool powered), setOnline(bool online)
- proposed addition: powerOn(), powerOff(), goOnline(), goOffline()
This with the proposed slotification, would make libofono-qt even easier
to use.
4. Use enumeration instead of strings:
for example in OfonoConnmanContext:
enum ContextType {
ContextTypeInternet,
ContextTypeMms,
ContextTypeWap,
ContextTypeIms,
};
void setType(ContextType type);
instead of:
void setType(const QString& type)
I know, that it is less flexible (especially if the oFono DBUS API
change), but it can help to reduce size of binaries and be slightly more
efficient. [On an ARM9@200MHz, every little helps! ;)]
3. bug with path()?
Each time my code call OfonoXyz.path(), I get a message in the console:
QDBusArgument: read from a write-only object
I don't know where does it come from, perhaps it's not even related to
ofono-qt...
4. partial interface implementation
There some classes that are missing properties/ function members.
On top of my head:
GSM band, UMTS band and fast dormancy in RadioSettings
5. More documentation (doxygen)
I know that by reading the ofono DBUS API, it's easy to figure out
how to use ofono-qt. But as ofono-qt offers an abstraction of the ofono
DBUS API, it might be nice to have a full ofono-qt API documentation.
I guess it would be mainly copy/paste from ofono/doc/*-api.txt.
6. Enhance ofono-qt with a concept of PIN agent?
It's easy to use SimManager.pinRequiredChanged() signals, but perhaps a
simple PIN agent class might be a nice thing to have.
At the SimManager level, or even better at the Modem level
OfonoModem.registerSimPinAgent(myAgent);
Just throwing some cheap ideas....

Chris

Looking at the link you gave, its hard to understand what your
technology does (without digging into the sources.) Can you please
give us a summary about it? Maybe a typical use case and a ten line
'easiest implementation' scenario?

It's a library that you would perhaps be interested to use if you are
writing your code in Qt C++ and want to access oFono d-bus services.
It abstracts away details of d-bus communication, selects the modem
for you and takes care of asynchronous operations. And there's also a
test suite for catching API breaks.

Right, so CE specifically has added those 3 first packages (cellular PIN query, and
settings). Those are available for upstream also, but probably not accepted for a reason
or other.
The last one is the new (Tablet) Settings application that is in MeeGo 1.2. Alex, you
could at least get in touch with owner of that component.

2011/7/4 Christian Gagneraud <chris(a)techworks.ie>:
So, to make it clear and simple, is there any official repository
for
ofono-qt?
If you mean a directory with official tarballs, there is no such
thing. I had assumed that anyone can roll their own tarball easily by
cloning the git repository and then using 'git archive'. Build systems
ought to be able to talk directly to git nowadays anyway :)
2. "slotification" of various member functions:
member functions like OfonoModem.setPowered(bool powered) could be declared
slots, so that it can be connected to signals of same signature like
QCheckBox.toggled(bool)
Yes - this will be fixed. Although you should be careful in connecting
property setting directly to dual state ui widgets like chechboxes -
there can be significant lag. Better to have a third state that
indicates that a property is being set or disable the checkbox until
the setting completes or fails.
3. More convenient function members (I'm getting picky, I know)
example for OfonoModem:
- existing: setPowered(bool powered), setOnline(bool online)
- proposed addition: powerOn(), powerOff(), goOnline(), goOffline()
This with the proposed slotification, would make libofono-qt even easier to
use.
It's an explicit design goal that ofono-qt provides a direct,
one-to-one mapping of ofono's d-bus interface. This means no
convinience functions on top or other bells and whistles (the only
exception is modem selection).
4. Use enumeration instead of strings:
for example in OfonoConnmanContext:
enum ContextType {
ContextTypeInternet,
ContextTypeMms,
ContextTypeWap,
ContextTypeIms,
};
void setType(ContextType type);
instead of:
void setType(const QString& type)
I know, that it is less flexible (especially if the oFono DBUS API change),
but it can help to reduce size of binaries and be slightly more efficient.
[On an ARM9@200MHz, every little helps! ;)]
This adds significant maintenance overhead with a gazillion of enums
that need to be kept up to date. Ofono API changes often, and I don't
think it's worth it.
3. bug with path()?
Each time my code call OfonoXyz.path(), I get a message in the console:
QDBusArgument: read from a write-only object
I don't know where does it come from, perhaps it's not even related to
ofono-qt...
I have no idea where it comes from either, because path() returns a
class member, and never even touches d-bus. Can you provide a
testcase?
4. partial interface implementation
There some classes that are missing properties/ function members.
On top of my head:
GSM band, UMTS band and fast dormancy in RadioSettings
Yep - I think these were added to ofono after the class had been
implemented. There is no easy way to keep those in sync (test cases
are not going to help here), but at some point I will go through the
ofono/doc/* and make a list of things to update. Or just send me
patches.
5. More documentation (doxygen)
I know that by reading the ofono DBUS API, it's easy to figure out how to
use ofono-qt. But as ofono-qt offers an abstraction of the ofono DBUS API,
it might be nice to have a full ofono-qt API documentation.
I guess it would be mainly copy/paste from ofono/doc/*-api.txt.
Again, significant maintenance overhead with too little benefit. It
would be truly a mind-numbing task to first doxygenize the textfiles
and then keep them in sync.
6. Enhance ofono-qt with a concept of PIN agent?
It's easy to use SimManager.pinRequiredChanged() signals, but perhaps a
simple PIN agent class might be a nice thing to have.
At the SimManager level, or even better at the Modem level
OfonoModem.registerSimPinAgent(myAgent);
It's that way, because ofono works that way. :) For those interfaces
where ofono is using d-bus agents (e.g. SIM toolkit), there will be
agents in ofono-qt as well.

Correct, and true for git master but not yet in a released "package".
I just SR'd the 0.1.4 version of libofono-qt prior to this weekend
and it's in Trunk:Testing at this point. I can't release a new
package for dialer until this moves into Trunk and/or one of the
MeeGo 1.2 branches since it depends on the multiparty call APIs I
added a few weeks back.
FYI... An added complication was just revealed to me, all MTF packages
have been deleted/removed from Trunk. So until dialer is completely
purged of all MTF deps (modulo anything provided by libmlite of course)
I can't push a new release of dialer into Trunk :(
Roland is doing a bunch of that work, and expects to be done around
July 18th. As I've not seen any of it yet, and we're still trying
to completely merge the HRP fork *and* migrate to libofono-qt, I
expect some added time (~1 week is a guess) to work through any merge
conflicts that arise.
Unfortunately I think Shane is on vacation.
Back now...

Two things come to mind:
1) A document that identifies which version of oFono the libofono-qt is
targeted for and some metric, like what percent of that version oFono's
API is complete/covered by this library.
2) A bit harder to do, espcially for the currently used CallHistory plugin,
but we need an API for getting call history signals and methods from the
agent providing that data.
On a matter related to 1) above, what is your plan for keeping pace with
oFono upstream releases and (maybe more important to this list) keeping
pace with oFono package updates in MeeGo OBS? No plan is a fine answer,
which should (hopefully) spark offers for help, but if you *do* have a
plan, I (and I assume others) would like to know what it is.
As usual I am happy to continue helping, but my responsiveness will still
only be as my time permits.

As Timo noted, rpm -q --whatrequires <package> does the trick on an
installed host.
I thought there was a zypper command to do something similar, but it's
not coming to me and a quick glance at the man pages is not revealing
an obvious answer... if anyone knows, please inform us ;)

I haven't given much thought to the process of 'certifying' ofono-qt
for a specific version of ofono until now. Like I said, I plan to go
through the implemented APIs looking for things that are missing or
have changed and documenting them, and we can take it from there. We
can also change the versioning scheme to match ofono's.
2) A bit harder to do, espcially for the currently used CallHistory
plugin,
but we need an API for getting call history signals and methods from the

Yep, I haven't done d-bus adaptors in Qt yet, so will take some time
to get it right.

I suppose there should be a more formal way of tracking changes in
ofono/doc/*. Perhaps by making a diff between two version tags that
then would serve as a TODO :)
I will write up a wishlist and post it here.

I will write up a wishlist and post it here.
Right, so this is the list of things in no particular order. If you
want any of them to happen faster, you are very much welcome to help.
Check the API and get it up to date:
- message manager should not use dbusobjectpath class
- connman contextAdd should return object path
- radio settings has missing stuff
- there might be plenty of other things
More formal "certification" of ofono-qt to specific ofono versions
- change the versioning to match ofono's
- when new version of ofono is out, diff of ofono/doc/* could serve
as a list of things to fix
Convert "void setPowered(bool powered)" type functions to public slots.
SIM toolkit bindings. This requires implementing a d-bus agent and some
kind of reasonable test.
- same for CallHistory.
When automatic modem selection is used, and ofono-qt class moves to using a
new modem, in addition to property change signal also other d-bus signal
subscriptions should be moved to the new modem path.
When interface availability changes, in addition to properties also lists of
object paths (such as voice calls, messages, GPRS contexts etc) should be
refreshed.
