Port configuration for location services on Telit HE910

Hi,

I'm trying to enable the LocationReporting interface in ofono. If I
understood the documentation correctly, in order for this interface to show
up in Manager.GetModems, I need first to send an appropriate AT command to
the device, for it to change to port configuration #8, and then power cycle
the board for changes to take effect.

I have tried the following:

# systemctl stop ofono
# cat /dev/ttyACM3 &
# echo 'AT#PORTCFG=8\r' > /dev/ttyACM3

OK

# reboot

But I still do not see the location reporting interface when running
Manager.GetModems:

# dbus-send --print-reply --system --dest=org.ofono /
org.ofono.Manager.GetModems
method return sender=:1.1 -> dest=:1.5 reply_serial=2

            )
         ]
      }
   ]


What am I missing?

Thanks,
Izhar

Reboot the modem, not the system.

I would enable AT command debugging and follow the logic inside 
drivers/telitmodem/location-reporting.c.  Maybe one of the AT commands 
fails or the ports are setup differently on your particular version of 
the hardware.
