We have a loop like that for MBIM modems. We query "Subscriber Ready Status" and if it tells us "Not Initialized" or "SIM not inserted", we sleep 1s and retry, up to 10 times. So not even that 10s loop would catch the issue you're seeing, if it needs up to 15s. I guess we could implement the same for QMI modems, or maybe even make it optional and only do it for the MC7750? Out of curiosity, have you tried different SIM cards? Also, is the firmware you're using the latest one available for the MC7750? > As a stopgap, is there a way to externally trigger MM to re-initialize a > device when we detect it's stuck (via DBus maybe?) without power cycling the > modem? > Hum... no, there is nothing like that right now. -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
