Reg Adding GPS NMEA & GPS RAW Capabilities to get GPS location using mmcli

[Ramu]

Hi,
Modem on my IMX6 Board :  Telit LE910C1-EU ( GSM and GPS )
Driver : option1 USB driver
Ports : ttyUSB0 to ttyUSB4
*NOTE 1 :* MM version           :   1.10.8 ( with
https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/commit/eb3f17ddccf9d54a1edd028eb0bd65380a93795a
patch )
Result : Just able to gps capabilities ( But not before applying patch)
mmcli -m 0 --location-status
  ------------------------
  Location | capabilities: 3gpp-lac-ci, gps-nmea, gps-unmanaged
           |      enabled: 3gpp-lac-ci
           |      signals: no
  ------------------------
  GPS      | refresh rate: 30 seconds

But the following error throwing ..


root at tcs-imx6:~# mmcli -m 0 --location-enable-gps-nmea
error: couldn't setup location gathering:
'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Connected: Couldn't
enable location 'gps-nmea' gathering'

mmcli -m 0 --location-enable-gps-unmanaged
error: couldn't setup location gathering:
'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Connected: Couldn't
enable location 'gps-unmanaged' gath'

*NOTE 2:*   #### Testing Now with MM 1.12.10 ######

Now not seeing the gps capabilities ...
There is no logs from modemmanager when i fired below commands  ..


mmcli -m 0 --location-status
mmcli -m 0 --location-enable-gps-nmea
mmcli -m 0 --location-enable-gps-unmanaged

*NOTE 3 :  *I have got GPS location data with following commands ( Manually
tried on ttyUSB2)
AT
AT$GPSNMUN=1,1,1,1,1,1,1      ##### After this cmd observe the outout data
on "cat /dev/ttyUSB1" on UART minicom.

AT$GPSACP          #### This is for Longitude


 #### Taken following logs from ModemManager daemon for NOTE 2 ######
LOG attached with the mail ..
