I applied patches you mentioned for UDEV tags ... Seems to be working now..
mmcli -m 0 --location-status
------------------------
Location | capabilities: 3gpp-lac-ci, gps-raw, gps-nmea, gps-unmanaged
| enabled: 3gpp-lac-ci
| signals: no
------------------------
GPS | refresh rate: 30 seconds
### *Enabling GPS working fine #*##
root@tcs-imx6:~# mmcli -m 0 --location-enable-gps-nmea
successfully setup location gathering
root@tcs-imx6:~# mmcli -m 0 --location-enable-gps-raw
successfully setup location gathering
root@tcs-imx6:~#
### *Do we need get any location Data here ??? ####*
root@tcs-imx6:~# mmcli -m 0 --location-get-gps-raw
error: no actions specified
root@tcs-imx6:~# mmcli -m 0 --location-get-gps-nmea
error: no actions specified
But the GPS data is comign on the ttyUSB1 port .. I have not connected any
passive or active antenna for GPS as of now.. But seeing below data ...
cat /dev/ttyUSB1
