Hi,
I'm using ModemManager 1.10.0, and libmbim 1.18.0 in conjunction with Telit
LE910-EU V2.
It all works fine, but I'm not able to set the preferred GSM mode or access
technology.
I'm confused by this error message "Cannot change modes: only one combination
supported', because only one mode is given.
Thank you for your help.
Carsten
