Run ModemManager in debug mode

[Frederic Martinsons]

Hi, for adding this to configure option , you need to add

EXTRA_OECONF +=  " --with-at-command-via-dbus"

to the modemmanager recipe or create a bbappend in your custom layer.

    build platform :- yocto

Hey

The --debug option gives you 2 things: debug log and AT command
support via the Command() API.

The mmcli -G DEBUG option only changes the debug log level.

If you need the AT command support via Command() you need either the
--debug option as you were using, or otherwise make sure you build
ModemManager using the --with-at-command-via-dbus configure option
