[Becker, Jochen]

Hi Loic,

ibmbim-utils/testing,now 1.26.4-1 amd64 [installed]
  Utilities to use the MBIM protocol from the command line

are installed and I got

wwan0at0    wwan0mbim0  wwan0qcdm0  

# mbim-network status /dev/wwan0mbim0 
Profile at '/etc/mbim-network.conf' not found...
error: unexpected command '/dev/wwan0mbim0'
usage: /usr/bin/mbim-network [OPTIONS] [DEVICE] [COMMAND]

# mbim-network /dev/wwan0mbim0 status
Profile at '/etc/mbim-network.conf' not found...
Getting status with 'mbimcli -d /dev/wwan0mbim0 --query-connection-
state '...
error: operation failed: NotInitialized
error: couldn't get connection status

Greatings
Jochen
