Hello,
I searched for a post with the same problem as mine, but without success.
Here is my issue:
I have an RG255C-GL modem connected to a Raspberry Pi with an M2 HAT.
The problem is that I can connect my modem to my 5G bubble using AT commands:
*at+QMAP=“WWAN” *
*+QMAP: “WWAN”,1,1,“IPV4”,“192.168.2.2” *
*+QMAP: “WWAN”,0,1,“IPV6”,“0:0:0:0:0:0:0:0” *
OK
I even have an IP address that appears here, I can ping (with AT command)…
But when I want to mount my wwan0 interface to get an IP address on my Raspberry, I get the following error:
