[Base hat] Newbie, am I missing something?

Hi guys!
I just bought a Base hat with Quectel EC25 module.

Hat mounted on Raspberry, USB cable connected.

I’m following tutorial “Internet Connection with Base HAT using ECM Mode”

  • lsusb correctly shows Quectel EC25 LTE module.

  • ifconfig:
    usb0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
    ether 52:13:24:ca:3c:67 txqueuelen 1000 (Ethernet)
    RX packets 0 bytes 0 (0.0 B)
    RX errors 0 dropped 0 overruns 0 frame 0
    TX packets 0 bytes 0 (0.0 B)
    TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

  • I correctly open minicom on ttyUSB2

  • AT+QCFG=“usbnet”,1 gives me OK

  • AT+CGDCONT=1,“IP”,“ibox.tim.it” gives me OK

  • AT+QCFG=“usbnet” gives me 1

  • AT+CPIN? gives me READY

  • AT+CREG gives me 0,1

  • AT+CGCONTRDP gives me +CGCONTRDP: 1,5,ibox.tim.it,10.40.19.159,217.200.201.67,217.200.201.66

After AT+CFUN=1,1 I get lost connection on minicom, but after connection rises agai I still get no IP address on USB0:
ifconfig usb0
usb0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether 22:7d:77:1b:14:46 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

So what’s wrong?
Thanks.

Hello,

Which variant of EC25 are you using?
What is the firmware version of the module?

Goodmorning,
variant is EC, I don’t know firmware version due I have not HAT here.
Are there differences among fw versions?
Thanks.

Yes,
Some FW may not work or show some issues.

Please contact the module vendor or Quectel Support for module-based issues.
