ModemManager warning messages

[ratnavel]

HI,

I am using a  ModemManager - 1.6.4 ( Ubuntu 16.06.4)  running on a Sierra
Wireless EM74xx modem

I happen to run the following command multiple times ( modem resets as part
of test functionality).

mmcli -m 1 --reset

The LTE interface came up fine and got connected after the reset but seeing
the warning messages from ModemManager every 30 secs.


*ModemManager[1462]: <debug> loading extended signal
information...ModemManager[1462]: <warn>  Couldn't load extended signal
information: Couldn't peek QMI port*

how can this be resolved? Is restarting the ModemManager the only option ?

Thanks,
Prakash
