DW5560 (Ericsson F5321) - GPS capability not available

[Marek Sebera]

Hey Aleksander,

thank you very much, this is correct solution, I've just tested.

After steps you recommended and enabling the modem:

# mmcli -m 0 --location-status

/org/freedesktop/ModemManager1/Modem/0
  ----------------------------
  Location |   capabilities: '3gpp-lac-ci, gps-raw, gps-nmea, gps-unmanaged'
           |        enabled: '3gpp-lac-ci'
           |        signals: 'no'
  ----------------------------
  GPS      |  refresh rate: '30'

# mmcli -m 0 --location-enable-gps-nmea
successfully setup location gathering

# mmcli -m 0 --location-enable-gps-raw
successfully setup location gathering

# mmcli -m 0 --location-status

/org/freedesktop/ModemManager1/Modem/0
  ----------------------------
  Location |   capabilities: '3gpp-lac-ci, gps-raw, gps-nmea, gps-unmanaged'
           |        enabled: '3gpp-lac-ci, gps-raw, gps-nmea'
           |        signals: 'no'
  ----------------------------
  GPS      |  refresh rate: '30'

# mmcli -m 0 --location-get

/org/freedesktop/ModemManager1/Modem/0
  -------------------------
  3GPP location   | Mobile country code: 'xxx'
                  | Mobile network code: 'xxx'
                  |  Location area code: 'xxxxx'
                  |             Cell ID: 'xxxxxxxx'
  -------------------------
  GPS NMEA traces | $GPGGA,,,,,,0,0,,,M,,,,*1B
                  | $GPGLL,,,,,000120.000,V,N*79
                  | $GPGST,000120.000,,,,0,,,*7A
                  | $GPGSV,1,1,00,,,,,,,,,,,,,,,,*79
                  | $GPGSA,A,1,,,,,,,,,,,,,,,*1E
                  | $GPRMC,000120.000,V,,,,,,,,,,N*4E
  -------------------------
  Raw GPS         | Not available
  -------------------------
  CDMA BS         | Not available

After changes in my distribution udev rules it looks like this:

-------
# Dell 5560
ATTRS{idVendor}=="413c", ATTRS{idProduct}=="818e",
ENV{ID_MM_ERICSSON_MBM}="1"

ATTRS{idVendor}=="413c", ATTRS{idProduct}=="818e",
ENV{.MM_USBIFNUM}=="09", ENV{ID_MM_ERICSSON_MBM_GPS_PORT}="1"
-----

Cheers!
