No, that's not it, you probably don't require QMI over MBIM here if your device is already using QMI. Try to add a "-p" to that qmicli command you're using. Looks like you may be trying to run QMI commands while other process (ModemManager?) is also using the port. Using "-p" will direct your QMI messages through the "qmi-proxy" that MM should have launched. -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
