Hi,
I'm trying to get the GPS data from my modem, but I receive "strange" 
character as output:

Under the item "Info" the modem-manager-gui in the network I can see the 
operator (Iliad), the operator code (22250) and so on, but under the 
Location item both the 3GPP (0/0/0/0/0) and the GPS location 
(0,000/0,000/0,000) are empty.

SO Linux Ubuntu 20.04, mmcli 1.12.8

Any help would be appreciated,
Angelo
