Hi Thomas,
thanks for your reply!
"Connect automatically" is set to "Any connection" but I have also tried
with "WLAN" and mobile internet.
What I have noted is that I can successfully initiate a connect-request
via dbus:
dbus-send --system --type=method_call --print-reply \
--dest=com.nokia.icd2 \
/com/nokia/icd2 \
com.nokia.icd2.connect_req \
uint32:1
When setting the value of the last parameter to uint32:0
(ICD_CONNECTION_FLAG_APPLICATION_EVENT) _no_ connection is established.
http://maemo.org/api_refs/5.0/5.0-final/icd2/group__dbus__api.html
According to my understanding, ICD_CONNECTION_FLAG_APPLICATION_EVENT
would silently initiate a connection in the background.
When the sessionProperty "ConnectInBackground" is set to True,
session.open() requests a connection with the
ICD_CONNECTION_FLAG_APPLICATION_EVENT flag:
http://qt.gitorious.org/qt/qt/blobs/4.7/src/plugins/bearer/icd/qnetworksession_impl.cpp
And that does not seem to work ...
Am I missing something?
To clarify my intention. I have an background application running that
periodically checks for updates via the Internet. if a connection cannot
be established, I do not want a modal user dialog to pop up. Connection
errors should be ignored silently.
Thanks,
Dominikb
p.s. I have already filed a bug report:

I try to open a QNetworkSession via session.open(). That works like a charm

default.

Is the "ConnectInBackground" sessionProperty implemented/available for
Maemo5 PR1.3/N900?
Depending on what you want to achieve, you might be able to use the
"native" (platform-specific) APIs on Maemo 5 to request internet
connectivity. They work and are fully implemented:
http://wiki.maemo.org/Documentation/Maemo_5_Developer_Guide/Using_Connectivity_Components/Maemo_Connectivity#Requesting_for_Connection
It might also depend on the settings of your device. Go to Settings ->
Internet connections and check the "Connect automatically" setting. If
you want to be able to connect in the background, it has to be set to
something else than "Always ask". If it still does not work with
QNetworkSession after checking this, it might be worth reporting this
as a bug on http://bugs.maemo.org/, even if you end up using libconic
for requesting the connection, so it can be fixed for future uses :)
HTH.
Thomas
