Hi,
I am trying to use ofono on a linux box with TELIT HE910. How can I enable stand-alone gps
using ofono, so that I can get GPS data without cellular connection?
Also when I tried running "test-gnss" for testing AGPS, I get the following
error(with ofonod daemon running in background):
NameError: name 'gnss' is not defined
Does this mean AGPS is not enabled? If so how can I enable it?
Regards,
Kiran

The location-reporting atom is enabled in pre-sim, so in theory you
should be able to use the modem as a GPS device without a SIM.
From what I remember, oFono HE910 GPS support requires fairly new
firmware and a special setting to work correctly. See
doc/telit-modem.txt for more information.
Also when I tried running “test-gnss” for testing AGPS, I get the
following error(with ofonod daemon running in background):
*NameError: name 'gnss' is not defined*
Yes, sounds like no modems with the
org.ofono.AssistedSatelliteNavigation interface were found.

Have you powered up your telit HE 910 via enable-modem?

Kiran: I followed the doc/telit-modem.txt(I set AT#PORTCFG=8 and rebooted the modem)and
the firmware version is 12.00.004.
After running the ofonod and test/enable-modem, I ran a script to get location info. It
gets disabled immediately.
One more observation is, I get "modem=/dev/ttyACM0 aux=/dev/ttyACM3
gps=/dev/ttyACM5" from ofonod logs, but /dev/ttyACM5 is
not accepting AT commands when I try from minicom.
Following are the logs:
./test/gn3

The test script I am using is:
import dbus
import sys
import glib
bus = dbus.SystemBus()
if len(sys.argv) == 2:
path = sys.argv[1]
else:
manager = dbus.Interface(bus.get_object('org.ofono', '/'),
'org.ofono.Manager')
modems = manager.GetModems()
path = modems[0][0]
print("Connecting modem %s..." % path)
modem = dbus.Interface(bus.get_object('org.ofono', path),
'org.ofono.LocationReporting')
fd = modem.Request()

Hi Kiran,
Following are the logs:
./test/gn3
Connecting modem /he910_0...

Everything looks as it should here.
The test script I am using is:
import dbus
import sys
import glib
bus = dbus.SystemBus()
if len(sys.argv) == 2:
path = sys.argv[1]
else:
manager = dbus.Interface(bus.get_object('org.ofono', '/'),
'org.ofono.Manager')
modems = manager.GetModems()
path = modems[0][0]
print("Connecting modem %s..." % path)
modem = dbus.Interface(bus.get_object('org.ofono', path),
'org.ofono.LocationReporting')
fd = modem.Request()
What do you expect the script to do actually?
Once you obtain the file descriptor, your client must be around to do
something with it (e.g. read NMEA strings).
As soon as the client(UNIX process) who performed the 'Request()'
operation exits, oFono closes the fd and shuts down the NMEA port on the
modem.
So everything is working as it should.

Kiran: I executed in the following order and ppp is up, but still I get the error:
*NameError: name 'gnss' is not defined*.
ofonod -> enable-modem -> activate-context
