Next time please explain the problem in text in the email itself instead of attaching a PDF, because that way search engines can map the emails in the public archive and that may also be helpful for others in the future ;) Looking at the steps you're following, it looks like you're manually connecting the modem (with mmcli?) and not using NetworkManager for that? If you connect the modem manually with mmcli, the IP settings are not automatically set in the network interface, which is what you're seeing. What you need to do is have NetworkManager trigger the bearer connection, without doing that yourself with mmcli. I can see how NM says the device is unmanaged; and given that this is a Yocto build, please make sure NetworkManager is built with the correct ModemManager support (i.e. configure with --with-modem-manager-1). Then, you can try to create a "gsm" connection in NM without any explicit "ifname"; that way, if you only have one single modem in your system, NetworkManager will try to find a suitable device for the connection: $ nmcli c add type gsm con-name quectel apn internet $ nmcli c up quectel If you do require the ifname, "cdc-wdm0" would have been the correct one to use, as that is the control port of the modem. -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
