Hi Denis,
Following are the logs:

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 am facing problem while reading from the file descriptor I got from
modem.request(). One 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.
Should I change gps port also to /dev/ttyACM3?

Hi Kiran,
Kiran: I am facing problem while reading from the file descriptor I
got from modem.request(). One 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.
Should I change gps port also to /dev/ttyACM3?
I'm not familiar with how GPS is setup on the he910. From what I
remember it is a dedicated port that is activated using $GPS* related
commands.
The port must be dedicated (so not /dev/ttyACM3) since the file
descriptor is being passed to an untrusted client.
