I configured APN and enabled ECM mode:
AT+CGDCONT=1,"IPV4V6","resiot.m2m"
AT+QCFG="usbnet",1
After reboot I see usb0 nic under linux, but without an IP address:
pi@NanoPi-NEO-Core:~$ ifconfig usb0
usb0 Link encap:Ethernet HWaddr ce:c9:96:67:18:6e
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

TX packets:14 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:3184 (3.1 KB) TX bytes:2170 (2.1 KB)
Of course, I can’t communicate.
However the modem seems connected:
AT+CGCONTRDP
+CGCONTRDP: 1,5,resiot.m2m,10.244.164.63,,194.151.228.34,194.151.228.18
OK
What’s the problem?
