Ofono use

Hi all,
I am currently trying to use ofono and I can not get how to register the
modem in a reliable way.
When I detect a modem, I set org.ofono.Modem.Powered to True.
When SimManager interface is ready, I enter the pin.
Then, I set the modem org.ofono.Modem.Online to True.
By the way, I wait for NetworkRegistration interface to be available.
When it is available, I wait for NetworkRegistration.Name to be non
empty to call NetworkRegistration.Register.

The point is setting Online property usually end with a timeout. It is
the right workflow ? Must I look for other property ? 

In a few words, what is the right workflow to get a UMTS modem
registered to its default network from the moment you plug it in ? 

Any piece of a clue will be appreciated :)


Regards,
Jean

So far so good...

oFono will automatically register unless the Mode property is set to
'manual'.  So calling NetworkRegistration.Register is wholly pointless
if you obtain a NetworkRegistration.Name.  That means you're already
registered ;)

What modem are you using?  In general Online should never result in a
timeout...

I am using a Huawei 1752 USB dongle.
After some time, modem is online, but I sometimes got a timeout. Really
precise, isn't it ? ;)

The really point now is I wanted to make voice calls but it appears that
this modem come with voice call feature disabled by default. Arggg.

At the end, setting Online to True always end in error if I follow the
workflow described above. Error is:
- First time:
Error setting online: org.freedesktop.DBus.Error.NoReply: Did not
receive a reply. Possible causes include: the remote application did not
send a reply, the message bus security policy blocked the reply, the
reply timeout expired, or the network connection was broken.
- Then, if I retry before 30sec:
Error setting online: org.ofono.Error.InProgress: Operation already in
progress

If I stop my program and come back after a while, modem is registered.
Modem is Huawei 1752USB

The registration might take some time (usually, however, much less than 25
seconds). Perhaps you have to adjust the SetProperty method timeout?

Sounds right to me. I would not wait for operator name, however.
