Unable to use DataConnectionManager

Unable to use DataConnectionManager

Hello,

I'm trying to make Ofono work with Telit modules using the atmodem driver. I succeeded in using all the features but the DataConnectionManager.

When I list the interfaces of the modem org.ofono.DataConnectionManager is missing. Using debug print I put, it seems that the probe function for the gprs interface is never called.

Is there something I should enable for using gprs capabilities?

Thanks,
Daniele

Since telit devices have not been properly integrated yet I assume you're 
using the atgen driver, correct?

The atgen driver would need generic PPP context support to enable GPRS 
properly.  This is something that is not quite ready in oFono today.  This is 
why the atgen driver does not enable support for GPRS.

If you want you can try to enable this in the atgen driver and try it out, but 
the code is still highly experimental.

Correct, I am using the atgen driver. I'm planning to add support for Telit devices, but first I would like to see how the atgen driver behaves.

Ok, if you tell me how I can give it a try and make some tests. Is it possible to use 0.20 version or should I use the GIT tree?

Thanks,

That would be great! I have a Telit UC864 but never had enough time to enable 
it properly.

You would need to use the git tree.  Simply add the following lines to atgen's 
post_sim function:
        gprs = ofono_gprs_create(modem, 0, "atmodem", data->chat);
        gc = ofono_gprs_context_create(modem, 0, "atmodem", data->chat);

        if (gprs && gc)
                ofono_gprs_add_context(gprs, gc);

See plugins/phonesim.c for an example.
