I'm looking into implementing the ModemManager portion of this in the u-blox plugin. In looking through the code, I noticed that the cinterion plugin implements the Modem3gpp interface (where the SetInitialEpsBearerSettings() method is defined) in mm-broadband-modem-cinterion.c, while the u-blox plugin's counterpart does not implement it, opting to use the generic 3gpp code instead. Is there a good way to add the SetInitialEpsBearerSettings() method to the u-blox plugin while still using all the rest of the generic 3gpp code? I would appreciate any guidance. Thanks, Andrew
