Re: AT port not attacted with RM520N-GL
Hi Aleksander, I found these two stable releases, which one you recommend given that we are currently using MM 1.16: https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/tags/1.22.0 https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/tags/1.20.6 Are there any libqmi and libmbim requirements for 1.20.6 ? (modemmanager - 1.16.6-3 libqmi - 1.28.6-3 libmbim - 1.24.8-2) Thanks, Pradeep G On Tue, Feb 13, 2024 at 2:19 PM Aleksander Morgado < aleksande...@chromium.org> wrote: > > > > Thanks for your reply, I will try out the suggested methods. > > And another thing is we are planning to update ModemManager > > ,currently we are at 1.16.6-2) and we can go to 1.20 stable versions. > > Is there any stable version that you can push into ModemManager sources? > > https://www.freedesktop.org/software/ModemManager/ > > > > Please use the signed git tags to retrieve the stable versions, we > stopped publishing tarballs some time ago. > > -- > Aleksander > -- This electronic communication and the information and any files transmitted with it, or attached to it, are confidential and are intended solely for the use of the individual or entity to whom it is addressed and may contain information that is confidential, legally privileged, protected by privacy laws, or otherwise restricted from disclosure to anyone else.

Re: No IP address for a successful connection on LTE modem
I think what confused me is that without the ModemManager i.e. using just cgact=1,1 to manually connect, i suddenly got an ip address assigned to the network interface provided by the modem. I thought it was NetworkManager running its dhcp client on that interface after getting a dhcp discover ? from the modem ? (i'm not too sure about how dhcp goes about its business) Anyway i have now tried to use Network Manager to setup and connect but now am getting the following message: modem-broadband[ttyUSB0]: failed to connect 'meig': Connection requested both IPv4 and IPv6 but dual-stack addressing is unsupported by the modem. and disabling ipv6 I get: failed to connect 'meig': Connection requested IPv4 but IPv4 is unsupported by the modem. Any idea where to start debugging that ? On 2/14/24 11:24, Aleksander Morgado wrote: Hey!

I see where you are going with this. It seems I expected more of the interaction between the ModemManager and Network Manager . To answer your question, no I have only used mmcli. Let me try the process with nmcli. :) NM only processes the connections that have been started via NM. There's a fundamental reason for that, which is that all the network-specific routing is done at NM level, MM knows nothing about it. In order for NM to know how to route traffic to through the LTE connection, it needs to use its own connection settings.
