Package: gpsd Version: 3.11-3 Severity: normal Dear Maintainer,
Some GSM/UMTS Modems built into Notebooks like the Lenovo T420 have GPS abilities. Previously it was possible to access the GPS via special MGM-GPSD Modules. But those have been discontiunued a while ago and are not being supplied with the Linux Kernel anymore, as the 'prefered' way to access the GPS not is via Serial interface. Those modems provide three, as far as I understand, identical serial interfaces. So you can use one as GSM Modem and another one as GPS. But you need to enable GPS function by issuing some AT commands: http://www.thinkwiki.org/wiki/Ericsson_F3507g_Mobile_Broadband_Module#Using_the_card_as_a_GPS_receiver AT*E2GPSCTL=1,1,1 AT*E2GPSNPD does the trick on mine. Unfortunately the modem resets itself when the serial device is closed. So you cannot use minicom or a script to put the modem in GPS Mode and then start gpsd. Also when gpsd would close the connection because no client is connected, this would reset the modem. Idealy, native detection for the F5521gw GPS would be built in into gpsd (ATI returns F5521gw) so that gpsd could initialize the GPS mode upon opening the serial device. I have been trying to send the serial commands with gpsctl -x , but this does not seem to work either. So my feature Request here is: Please to add support for F5521gw GPS detection and initialization, or add a way to send an arbitary init string to the serial gps device when opening the device. -Benoit- -- System Information: Debian Release: 8.8 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.16.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=de_CH.UTF-8, LC_CTYPE=de_CH.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages gpsd depends on: ii adduser 3.113+nmu3 ii init-system-helpers 1.22 ii libbluetooth3 5.23-2+b1 ii libc6 2.19-18+deb8u9 ii libdbus-1-3 1.8.22-0+deb8u1 ii libgps21 3.11-3 ii libusb-1.0-0 2:1.0.19-1 ii lsb-base 4.1+Debian13+nmu1 ii netbase 5.3 ii systemd-sysv 215-17+deb8u7 Versions of packages gpsd recommends: ii python 2.7.9-1 ii udev 215-17+deb8u7 Versions of packages gpsd suggests: ii dbus 1.8.22-0+deb8u1 ii gpsd-clients 3.11-3 -- Configuration Files: /etc/default/gpsd changed: START_DAEMON="true" GPSD_OPTIONS="" DEVICES="/dev/gps0" USBAUTO="false" GPSD_SOCKET="/var/run/gpsd.sock" -- debconf information: * gpsd/daemon_options: * gpsd/start_daemon: true * gpsd/device: /dev/gps0 * gpsd/autodetection: false * gpsd/socket: /var/run/gpsd.sock
