N900 dbus interfaces - maemo.org

jonwil | # 1 | 2012-07-28, 04:16 | Report

I have created a Wiki post to document the known Nokia-specific dbus interfaces used on the N900.
http://wiki.maemo.org/N900_dbus

Let me know if you have any feedback on the page or if you have anything to add to it.

Excellent compilation. Can you tell us how you found out all this?
Also, do you also have the time and inclination to do the same for the n9's dbus interfaces?

Thanks.

Some of the information came from source packages for various things (e.g. bluez, QT etc), some of it came from dev packages in the SDK, some of it came from wiki entries, mailing list messages and forum posts and some of it was just plain reverse engineered. Some of it came from dbus introspection.

As for the N9, no I dont intend to do that one because I dont own an N9 (which means I cant do what I did with the N900 and try out different calls to see if they work)

There is also a good tool in terminal .

qdbus this tool you can list all running dbus services and lists method/signals and even execute methods

Unbelievable, jonwil!
I am speechless.

THANKS

I couldn't find this nice tool so I created one from QT4.8 source compiled with harmattan toolchain.
That is why you need for the N900 a different lib.
This ugly hack was for me the fastest. Otherwise I need to recode qdbus. However for quick check some dbus it is nice. Don't know if my method can harm the system, could be that it hang up? Try at your own risk.
Here for sharing.. have a nice dbus hacking.

The mount binding is not needed for Harmattan.

Code:

chmod +x qdbus
mount --bind libstdc\+\+.so.6.0.12 /usr/lib/libstdc\+\+.so.6.0.9
./qdbus

after usage:

Code:

umount /[your_path]/libstdc\+\+.so.6.0.12

If there is already a qdbus package for N900 or a better way to point to the library do not hesitate to post

EDIT! removed attachment because uploaded qqdbus to extra

sadly that I can't run qdbusviewer on N900.
I will add a screenshot for N950.

I replaced the broken qqdbus package and uploaded it to extras.
There is a app in development called qdbusviewer and you have a console command qdbus.

The qdbusviewer needs some gui improvements. Will see what the future brings. Also I want to add the address option from QT4.8.
Still has the xml option which was added to qqdbus maemo package.

Edit: all autobuilder problems are fixed now

thanks! i will try it! before the only possibility to see dbus methods was the command

dbus-send --session --dest=com.nelisquare --type=method_call --print-reply /com/nelisquare org.freedesktop.DBus.Introspectable.Introspect

in this case shows the methods for nelisquare are, top_application only
