Oops... although this is unrelated to this patch itself if I'm not mistaken; the issue was there before as well? Does this mean that we were not getting SIM removal notifications as soon as the modem was enabled? A quick solution would be to subclass the enabling_modem_init() step and after running the parent method, run a Telit specific setup to check #CSS? and if disabled due to the ATZ, re-set it, would that work? -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
