Re: nmcli and cdc-wdm0 device for UMTS connection

2018-09-18 Thread Giovanni Parodi via networkmanager-list 
First, thank you for your help.
I entered the ifname cdc-wdm0 because of the tutorial that I found at the
following link:
https://docs.ubuntu.com/core/en/stacks/network/network-manager/docs/configure-cellular-connections

They say:
 is the string listed as “primary port” in the output from 'sudo
mmcli -m ' (as previously described)

The modem primary port in mmcli -L is
cdc-wdm0

However I tried entering the following command:
nmcli c add type gsm ifname "*" con-name remoteConnection apn ibox.tim.it

and once again the reply to command
nmcli con up remoteConnection

is:
Error: Connection activation failed: No suitable device found for this
connection

Did I understand your suggestion to use a * as ifname?
Thank you
Giovanni

Hi,

in the output of `nmcli device` there is no device named "cdc-wdm0". It
seems, to NetworkManager, the device is called differently. Since there
is only one wwan typed device, the name seems to be "wwan0"?


Also, you don't need to restrict the profile to a device by name, if
that doesn't suit you. Just specify an empty name.

best,
Thomas

nmcli and cdc-wdm0 device for UMTS connection

2018-09-18 Thread Giovanni Parodi via networkmanager-list 
Hello everybody,
I have a problem connecting to a UMTS network on an embedded system.
Here are the details:
- Modem Quectel UC20
- packages installed: usbutils, usb_modeswitch, NetworkManager (1.0.4),
ModemManager (1.4.2).

To activate network connection, I work as follows:

// Start ModemManager with log debug
ModemManager --debug &

// Enable modem
mmcli -m 0 -e

// Start NetworkManager
NetworkManager &

// cdc-wdm0 is the primary port oc the modem, look at the following
text.
*nmcli c add type gsm ifname cdc-wdm0 con-name remoteConnection apn
ibox.tim.it *

// By this command I'm able to verify that the modem is registered to
the network
mmcli -m 0 -w

Output is
/org/freedesktop/ModemManager1/Modem/0: Initial state, 'registered

The output of the command
mmcli -m 0
is:

/org/freedesktop/ModemManager1/Modem/0 (device id
'fdecd6b32808f6d001a07e35d54ac8635ac19228')

So, once again, it seems the modem is registered.
However the output of the command
nmcli con
is as follows:

NAME  UUID  TYPE  DEVICE
remoteConnection  3c1a500d-fc67-4523-9ba9-6973249a859a  gsm   --

So it seems that the remoteConnection is not associated with any device (I
think that the device should be cdc-wdm0).

The output of
 nmcli dev
is:

DEVICE   TYPE  STATE CONNECTION
can0 can   disconnected  --
can1 can   disconnected  --
tunl0ipip  disconnected  --
wlan0wifi  disconnected  --
wwan0wwan  disconnected  --
bond0bond  unmanaged --
eth0 ethernet  unmanaged --
gre0 gre   unmanaged --
gretap0  gretapunmanaged --
lo   loopback  unmanaged --

And running the command
nmcli con up remoteConnection
I get the error:
Error: Connection activation failed: No suitable device found for
this connection

I'm working on an embedded device without gui, and the SW version are the
following ones:
   nmcli  version 1.0.4
mmcli version 1.4.2
I'm not able to upgrade those applications.

Is there any other test, further investigation that I can perform on this
topic?
Any help will be appreciated
Best regards
Giovanni
