No ipv4 addedd to the wwan0 device #6

Open gabri94 opened 4 years ago

gabri94 commented 4 years ago

I managed to get the plugin and modemmanager running, however it doesn't add the ipv4 address to my wwan0 device. I managed to find it using mmcli -b 0 and if i add it manually to the device it works, however it is not added by default.

I tryied to debug the code in mm-bearer-xmm7360.c, and i found that self->priv->ip_config actually contains the address, nonetheless it is not addedd to the wwan device.

By serching around it might be a network manager issue, but i can't understand why or how. This is the network manager log:

I'm quite curious why your log shows the new Broadband device message after the IP config has already been fetched... In my log this message appears way before I even activate the connection (Some seconds after ModemManager has been started). But on the other hand, NetworkManager already knows about the modem, otherwise you wouldn't be able to start the connection anyway, I assume.

is there a way to enable debug info in networkmanager?
