[ublox] A problem with the network connection over LTE on TOBY-L2
Hello everyone, I've tried to establish a connection using ModemManager through LTE network and haven't succeed in it. However, I am able to successfully set up an internet connection manually, given the same conditions but without ModemManager, applying the steps suggested in Sec. 5.10.2 of [1]: AT+CFUN=4 AT+UCGDFLT=1,"IP","internet.t-mobile.cz" -- sets the default PDP context which is applied right after a registration. AT+CFUN=1 When I use ModemManager (mmcli -m0 --simple-connect="apn=internet.t-mobile.cz"), it apparently configures a PDP context in the same way as for 3G/2G networks. The modem gets an IP and DNS addresses, but pings are not passing through it.. Please, see the logs and the modem info below. root@zynq7:~# mmcli -m 0 /org/freedesktop/ModemManager1/Modem/0 (device id '9be611a4f382a582972f20fa86efbaa8f6b02918') - Hardware | manufacturer: 'u-blox' | model: 'TOBY-L210' | revision: '15.63' | H/W revision: 'unknown' | supported: 'gsm-umts, lte' |current: 'gsm-umts, lte' | equipment id: '###' - System | device: '/sys/devices/soc0/amba/e0002000.usb/ci_hdrc.0/usb1/1-1/1-1.2' |drivers: 'cdc_ether, cdc_acm' | plugin: 'u-blox' | primary port: 'ttyACM0' | ports: 'ttyACM0 (at), ttyACM1 (at), ttyACM2 (at), wwan0 (net)' - Numbers | own : 'unknown' - Status | lock: 'none' | unlock retries: 'sim-pin (3), sim-pin2 (3), sim-puk (10), sim-puk2 (10)' | state: 'searching' |power state: 'on' |access tech: 'unknown' | signal quality: '40' (recent) - Modes| supported: 'allowed: 2g; preferred: none | allowed: 2g, 3g; preferred: none | allowed: 2g, 3g; preferred: 2g | allowed: 2g, 3g; preferred: 3g | allowed: 3g; preferred: none | allowed: 4g; preferred: none | allowed: 2g, 3g, 4g; preferred: none | allowed: 2g, 3g, 4g; preferred: 2g | allowed: 2g, 3g, 4g; preferred: 3g | allowed: 2g, 3g, 4g; preferred: 4g | allowed: 2g, 4g; preferred: none | allowed: 2g, 4g; preferred: 2g | allowed: 2g, 4g; preferred: 4g | allowed: 3g, 4g; preferred: none | allowed: 3g, 4g; preferred: 3g | allowed: 3g, 4g; preferred: 4g' |current: 'allowed: 4g; preferred: none' - Bands| supported: 'egsm, dcs, pcs, g850, utran-1, utran-3, utran-4, utran-6, utran-5, utran-8, utran-2, utran-7, eutran-1, eutran-2, eutran-3, eutran-4, eutran-5, eutran-7, eutran-8, eutran-11, eutran-13, eutran-17, eutran-20, utran-11' |current: 'egsm, pcs, g850, utran-1, utran-5, utran-8, utran-2, eutran-1, eutran-2, eutran-5, eutran-8' - IP | supported: 'ipv4, ipv6, ipv4v6' - 3GPP | imei: '###' | enabled locks: 'none' |operator id: 'unknown' | operator name: 'unknown' | subscription: 'unknown' | registration: 'idle' |EPS UE mode: 'csps-2' - SIM | path: '/org/freedesktop/ModemManager1/SIM/0' - Bearers | paths: 'none' root@zynq7:~# mmcli -b 0 Bearer '/org/freedesktop/ModemManager1/Bearer/0' - Status | connected: 'yes' | suspended: 'no' | interface: 'wwan0' | IP timeout: '20' - Properties | apn: 'internet.t-mobile.cz' | roaming: 'allowed' | IP type: 'none' |user: 'none' |password: 'none' | number: 'none' | Rm protocol: 'unknown' - IPv4 configuration | method: 'dhcp' | address: '100.90.53.103' | prefix: '32' | gateway: '100.90.53.103' | DNS: '93.153.117.49', '93.153.117.17' - IPv6 configuration | method: 'unknown' - Stats | Duration: '3330' |Bytes

But there is no > IPAddr/Gateway assigned Ok, it looks like ModemManager is attempting to use PPP on the device because MM doesn't handle the Telit cdc-ncm ethernet-like interface that the modem provides. Ideally we'd like to use that interface, rather than PPP but that's unimplemented for now, it seems. But with your current setup, MM is waiting for you to start pppd on the data port to configure the IP details.
