Hey, The current openwrt integration suffered from a serious problem: network initiated disconnections were properly detected by MM but never reported to netifd. Due to this, the modem may end up in registered state while netifd thinks it is still connected.
I reported about this issue here: https://github.com/openwrt/openwrt/issues/8368 After discussing the problem with one of the openwrt maintainers, they suggested a way to report the disconnection of the interface to netifd. In order to run the operations they suggested, I've added support for connection status dispatch scripts in ModemManager. These are scripts that distributions or users could install, equivalent to what we do with the FCC unlock scripts, and which are run whenever a bearer gets connected or disconnected. The work is ready for review/testing here: https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/775 In that same bugreport I've pushed also the dispatcher script that I would attempt to integrate in the openwrt packaging once the dispatcher script support is shipped in a ModemManager release. Comments and tests welcome! Cheers -- Aleksander https://aleksander.es
