You need to investigate why that happens, because it doesn't make much sense. It is true that the MBIM session is kept open by the proxy, but other than that, there is no other interaction triggered by the proxy itself, the only interactions done by the proxy are triggered by connected clients. If your client connects to the proxy, you should be able to send messages without any problem. > Could we stop the mbim-proxy during update and restart > it after update ? > That is currently not possible, stopping the mbim-proxy will break other firmware upgrade processes, like the one for the DW5821e. If there is any issue triggered by the proxy itself, we should fix the proxy, not stop it -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
