Thanx for the quick answer,
what I don't really understand is the difference between drivers and plugins in ofono.
Let's take an example: I need radio-settings interface to get and set the technology preference. This interface is not implemented in atmodem driver.
Is it better to extend atmodem driver or to create a new driver? If I can do it in plugin it would be fine, but how?
Plus I will need to extend the dbus interfaces to have some more method. Looking at the dbus code I see that it calls the driver implementations, so I think I have to either extend the atmodem driver or to create a new one.
Am I missing someting?
