That method was never meant to be exported in libmm-glib, so it makes sense it's no longer available. If it was available before, it was a bug. The reason for this is that the bearer IP config is created by the ModemManager daemon and exposed in DBus, and so users of libmm-glib can use MMBearerIpConfig to *read* the settings provided by ModemManager. The user selection of the IP type to use can be done either in Simple.Connect() or in Modem.CreateBearer(): https://www.freedesktop.org/software/ModemManager/doc/latest/ModemManager/gdbus-org.freedesktop.ModemManager1.Modem.html#gdbus-method-org-freedesktop-ModemManager1-Modem.CreateBearer https://www.freedesktop.org/software/ModemManager/doc/latest/ModemManager/gdbus-org.freedesktop.ModemManager1.Modem.Simple.html#gdbus-method-org-freedesktop-ModemManager1-Modem-Simple.Connect In libmm-glib there are helper types for those as well, see MMBearerProperties and MMSimpleConnectProperties: https://www.freedesktop.org/software/ModemManager/doc/latest/libmm-glib/MMBearerProperties.html https://www.freedesktop.org/software/ModemManager/doc/latest/libmm-glib/MMSimpleConnectProperties.html The user will select IP type to use in either MMBearerProperties or MMSimpleConnectProperties and then MM will expose which one was agreed with the network in the read-only MMBearerIpConfig. They may be different only if user selected IPv4v6, because we won't fail a connection attempt if we cannot get dual-stack (e.g. we may get IPv4 only even if we requested IPv4v6). -- Aleksander https://aleksander.es
