I assume this is your own custom system build? If so, I think there's some kernel driver missing because we're not seeing the cdc-wdm ports associated to the wwan net ports. Do you have both the qmi-wwan and the cdc-wdm kernel drivers enabled? > -------------------------------- > Numbers | own: +XXXXXX > -------------------------------- > Status | unlock retries: sim-pin (3), sim-puk (10) > | state: enabled > | power state: on > | signal quality: 0% (cached) > -------------------------------- > Modes | supported: allowed: 2g, 3g, 4g; preferred: none > | current: allowed: 2g, 3g, 4g; preferred: none > -------------------------------- > IP | supported: ipv4, ipv6, ipv4v6 > -------------------------------- > 3GPP | imei: XXXXXXXX > | registration: idle > -------------------------------- > 3GPP EPS | ue mode of operation: csps-2 > -------------------------------- > SIM | dbus path: /org/freedesktop/ModemManager1/SIM/0 > > > > # mmcli -m 0 --location-status > ------------------------ > Location | capabilities: 3gpp-lac-ci > | enabled: 3gpp-lac-ci > | signals: no > > > Any pointers on how to change the gps port to be used correctly ? > The GPS support for these modules is not implemented in ModemManager using the TTY port (even if the port is flagged as GPS); it would be possible to do so, it's just not implemented. But we do allow QMI-based GPS management in the MC7455 in QMI mode, using the QMI LOC service. We just need to detect the modem in QMI mode, and for that we need the QMI control ports (cdc-wdm) to be exposed by the system. -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
