Related to QMI IPv4 - MM_BEARER_IP_METHOD_STATIC

Believe it or not after the first successful connectionbut via "qmicli ... --wds-start-network..." connection started to work, although not in the way as it would be expected.
As I wrote before, one step forward, two steps back. :)


# qmicli -d /dev/cdc-wdm0 --wds-start-network="<APN>,pap,<USER>,<PASSWD>" --client-no-release-cid
[/dev/cdc-wdm0] Network started
	Packet data handle: '<PDH>'
[/dev/cdc-wdm0] Client ID not released:
		Service: 'wds'
	    CID: '<CID>'
# dhclient wwan0

# qmicli -d /dev/cdc-wdm0 --wds-get-packet-service-status
[/dev/cdc-wdm0] Connection status: 'connected'

# dhclient -r wwan0
# qmicli -d /dev/cdc-wdm0 --wds-stop-network=<PDH> --client-cid=<CID>
Network cancelled... releasing resources
[/dev/cdc-wdm0] Network stopped

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

$ mmcli -m 0 --simple-connect="apn=<APN>,allowed-auth=pap,user=<USER>,password=<PASSWD>,allow-roaming=no"
# dhclient wwan0

$ mmcli -m 0 --simple-status | grep state | awk '{print $3$4}'
state:'connected'

# dhclient -r wwan0
$ mmcli -m 0 --simple-disconnect

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

$ nmcli device connect cdc-wdm0
or
$ nmcli connection up <ID>
# dhclient wwan0

$ nmcli -f GENERAL.STATE device show cdc-wdm0 
GENERAL.STATE:                          100 (connected)
or
$ nmcli -f GENERAL.STATE connection show <ID> 
GENERAL.STATE:                          activated

# dhclient -r wwan0
$ nmcli device disconnect cdc-wdm0
or
$ nmcli connection down <ID>

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

$ nm-applet
No matter what the data interface i.e. "wwan0" already picked the right address, due to the additional steps required to actually provide a  connection, that is a DHCP client address request & release, 
network-manager-applet as a GUI ain't very useful per se.
