GPSD does not start on boot

[Stelios Pa]

Hi,

thanks again for the great support team you have, it really matters on a great product, a great support team.

I’m currently using 1.6.0-RC1 AEP firmware on MTCDT-LEU1-266A and I’m trying to fetch GPS information. I had no luck with 1.4.17 version too.

From the GUI, I have not changed anything, I haven’t enabled neither server or client mode.

When i SSH in the device and try ps aux | grep gps I can se only
admin 2747 0.0 0.3 24728 884 ? Ssl 17:06 0:00 /sbin/mtsgps --en2-load --daemonize --device /dev/ttyXRUSB2

After manually running /etc/init.d/gpsd start I can see

Starting GPS (Global Positioning System) daemon gpsd
gpsctl:ERROR: /dev/ttyXRUSB2 already opened by another process
gpsctl:ERROR: initial GPS device /dev/ttyXRUSB2 open failed
Expect a timeout error here. Need this error.
gpsctl:ERROR: /dev/ttyXRUSB2 already opened by another process
gpsctl:ERROR: initial GPS device /dev/ttyXRUSB2 open failed

and with ps

admin     2747  0.0  0.3  24728   884 ?        Ssl  17:06   0:00 /sbin/mtsgps --en2-load --daemonize --device /dev/ttyXRUSB2

my /etc/default/gpsd configuration file is the original one

ENABLED="yes"
GPSD_SOCKET="/var/run/gpsd.sock"
GPSD_OPTIONS="-n -D 1"

# Conduit 0.1 GPS devices
GPS_LINE=/dev/ttyXRUSB2

# Highest speed permitted by uBlox.
GPS_BAUD=115200
GPS_DEVICES="$GPS_LINE /dev/pps0"

GPS_FIXFILE=/var/run/gpsfix

# GPSD/UBlox Lock requiremnt
# Create GPS_FIXFILE when reached.
# UBlox NAV SOL (0x01 0x06) at gpsFix value
# and above
# 00 No Fix
# 01 Dead reckoning only
# 02 2D fix
# 03 3D fix
# 04 GPS + dead reckoning combined
# 05 Time only fix
GPSFIX="03 05"

should gpsd autostart by default or /sbin/mtsgps correctly replace it ?

After killing /sbin/mtsgps and restarting gpsd, it seems to have better luck and now I can use gpsmon and cgps but with “No FIX”

/var/log/messages

2018-08-14T17:51:54.552131+03:00 mtcdt admin: Problem with the GPS fix.  The fix is an even value, "4", and should be an odd value.  fixOK=0
2018-08-14T17:51:54.581878+03:00 mtcdt admin: GPS does not have a fix yet.  Try again later.

Stelios,

Try doing “/etc/init.d/mts-gps stop” before starting gpsd. If that fixes the problem, then the mts-gps daemon needs to be disabled before gpsd will start.
