Hi all guys!
I came across one of the strangest devices ever, at least to me: a Huawei E3131
device:
Model: E3131
Revision: 21.157.41.01.1037
But the usb id says a different story:
Bus 003 Device 023: ID 12d1:1506 Huawei Technologies Co., Ltd. E398
LTE/UMTS/GSM Modem/Networkcard
But this hardware in particular doesn't support LTE.
the device is handled by option + cdc_ncm - and that sounds right.
Now - the problem: with the
at^ndisdup
or
at^ndisconn
commands, it is not possible to establish a connection. How can this device be
used without PPP?
I saw some patches in modemmanager, but can't understand exactly how things
work.
I know this is not the right list to post this question - but my hope is that
someone could help me understand.
thank you all!!
