DW5560 (Ericsson F5321) - GPS capability not available

[Marek Sebera]

Hi,

on Dell E6430 with DW5560 (Ericsson F5321) card installed, I can use
mmcli to correctly connect to the internet, it works pretty nice :)

However I am not able to control modem GPS capabilities through MM.
Previously I enabled GPS NMEA stream through wvdial conf like this:

[Dialer gps]
Modem = /dev/ttyACM0
Init1 = AT*E2GPSCTL=1,2,1
Init2 = AT*E2GPSNPD

After I could read the stream on /dev/ttyACM0 and hook ie. gpsd to it.

However mmcli does not show the GPS capabilities before or after running
this command (or running the wvdial gps and restarting/reruning-search
in mmcli), also I've tried to switch modes by "options cdc_ncm
prefer_mbim=N" (or =Y), without success.

# mmcli -m 0 --location-status

/org/freedesktop/ModemManager1/Modem/0
  ----------------------------
  Location |   capabilities: '3gpp-lac-ci'
           |        enabled: '3gpp-lac-ci'
           |        signals: 'no'

Device is identified as "Bus 004 Device 003: ID 413c:818e Dell Computer
Corp." Revision (by mmcli -m 0) is "R3C11" (R3C11/R4D02 i suppose)
Partial device identification as follows:

# mmcli -m 0

/org/freedesktop/ModemManager1/Modem/0 (device id '--censored--')
  -------------------------
  Hardware |   manufacturer: 'Dell'
           |          model: 'DW5560'

           |      supported: 'gsm-umts'
           |        current: 'gsm-umts'
           |   equipment id: '--censored--'

           |        drivers: 'cdc_acm, cdc_ncm, cdc_wdm'
           |         plugin: 'Ericsson MBM'
           |   primary port: 'ttyACM1'
           |          ports: 'ttyACM1 (at), cdc-wdm0 (at), cdc-wdm1
(at), wwp0s29u1u6i6 (net), ttyACM2 (at), ttyACM0 (at)'

Can you advise on how to get the gps capability shown and enabled?

I'm using these versions of packages (Debian Stretch with sid aptitude
list):

1.18.0-2	libqmi-glib5:amd64
1.18.0-2	libqmi-proxy
1.18.0-2	libqmi-utils
1.10.2-2	libqmi-glib1:amd64
1.6.8-1		gir1.2-modemmanager-1.0:amd64
1.6.8-1		modemmanager
1.6.8-1		modemmanager-dev:amd64

Thank you!
Ms
