Hello. I've built OpenWrt from trunk (Kernel 4.4.14) including ModemManager and its dependencies.
With my mc7455 in QMI mode, PPP interface is established and the internet is accessible. With modem in MBIM mode, expected interface (not PPP) is brought online - although strangely with an IP from an entirely different network (than when in QMI), and the internet is not reachable. Please bear with me - I'm new to all of this. Some outputs attached: *Found 1 modems:* * /org/freedesktop/ModemManager1/Modem/0 [Sierra] MBIM [1199:9071]* */org/freedesktop/ModemManager1/Modem/0 (device id '1404de2498fc8078e94bc55ab5ac5e4872bbf081')* * -------------------------* * Hardware | manufacturer: 'Sierra'* * | model: 'MBIM [1199:9071]'* * | revision: 'SWI9X30C_02.20.03.00'* * | supported: 'gsm-umts, lte'* * | current: 'gsm-umts, lte'* * | equipment id: 'XXXXXXXXXXXXXX'* * -------------------------* * System | device: '/sys/devices/platform/ehci-platform.1/usb2/2-1'* * | drivers: 'che l'* * | plugin: 'Sierra'* * | primary port: 'cdc-wdm0'* * | ports: 'ttyUSB0 (qcdm), ttyUSB1 (at), cdc-wdm0 (mbim), wwan0 (net)'* * -------------------------* * Numbers | own : 'unknown'* * -------------------------* * Status | lock: 'none'* * | unlock retries: 'sim-pin2 (3)'* * | state: 'registered'* * | power state: 'on'* * | access tech: 'lte'* * | signal quality: '19' (cached)* * -------------------------* * Modes | supported: 'allowed: 3g, 4g; preferred: none'* * | current: 'allowed: 3g, 4g; preferred: none'* * -------------------------* * Bands | supported: 'unknown'* * | current: 'unknown'* * -------------------------* * IP | supported: 'ipv4, ipv6, ipv4v6'* * -------------------------* * 3GPP | imei: 'XXXXXXXXXXXXX'* * | enabled locks: 'fixed-dialing'* * | operator id: '310120'* * | operator name: 'Sprint'* * | subscription: 'unknown'* * | registration: 'home'* * -------------------------* * SIM | path: '/org/freedesktop/ModemManager1/SIM/0'* * -------------------------* * Bearers | paths: '/org/freedesktop/ModemManager1/Bearer/4'* *config interface 'wwan'* * option device '/sys/devices/platform/ehci-platform.1/usb2/2-1'* * option proto 'modemmanager'* * option apn 'X.XX.XXXXX'* * option lowpower '1'* *wwan0 Link encap:Ethernet HWaddr 5A:60:06:DC:00:57 * * inet addr:XX.XX.XXX.XX Bcast:XX.XX.XXX.XX Mask:255.255.255.252* * inet6 addr: fe80::5860:6ff:fedc:57/64 Scope:Link* * UP BROADCAST RUNNING NOARP MULTICAST MTU:1500 Metric:1* * RX packets:0 errors:0 dropped:0 overruns:0 frame:0* * TX packets:817 errors:0 dropped:0 overruns:0 carrier:0* * collisions:0 txqueuelen:1000 * * RX bytes:0 (0.0 B) TX bytes:51020 (49.8 KiB)* *default via XX.XX.XXX.XX dev wwan0 src XX.XX.XXX.XX* *XX.XX.XXX.XX/29 dev wwan0 src XX.XX.XXX.XX * For comparison sake - the modem works as expected in both QMI and MBIM mode on Ubuntu 16.10 which has raw-ip support in the updated qmi_wwan driver. I'd still expect OpenWrt with kernel 4.4 to work properly in MBIM. Thank you for any help you can provide.
