Hi Aleksander,
something changed, now I can see the 3GPP position, but the GPS stream
is always corrupted:
mmcli -m 0 --location-get
--------------------------
3GPP | operator code: 222
| operator name: 50
| location area code: 86E9
| tracking area code: 0000
| cell id: 01D0DA11
--------------------------
GPS | nmea: ¤ÅAΦUiΔΠ,,1aBéØΠ,X0aBEΓΩ5f4P
| ¤ÅA:t(ΔΠ,X0aBéøΠ,X0aBéØΠ*lXi
| ¤ÅA2Ej_Π,(1aRÇØΠNX0YDEΓΩ2ù5P
Λ | ¤ÅA:4*ΔΠAXDaBéØΠ,X0aBéØΠ,X0a"%L"
As I remember, I put NetworkManager and ModemManager in debug mode and I
got this (only two blocks as example):

Hey,
I'm trying to get the GPS data from my modem, but I receive "strange"

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
Please update to libqmi to 1.24.12, I believe this issue happens due
to the CRLF on the NMEA traces being filtered out, and so libqmi
attempts to parse the string with a different encoding.
