Question

I bought a brand-new RUTX11 and updated it to the newest Firmware.

Everything so far is working fine except for GPS

I use a Poynting puck 5in1 antenna. Also tried the included gps antenna.

it says no gps signal in the gui. i can measure about 3 volts at the terminal for the antenna.

What can i do to get it to work? Already tried to downgrade Firmware to 7.01.2 but no gps as well....

Hardware revision is 0808....

Answer 1

Hello, 

Regarding this issue of yours kindly check the following: 

1. Kindly try putting the GPS antenna outside where it can see the open sky. 
2. After doing that try to execute this command via CLI: gpsctl -ixap take a screenshot and share the results.
3. If no response on that command execute this: /etc/init.d/gpsd restart and then retry executing gpsctl -ixap
4. If still not working, don't reboot the device and share a copy of the Troubleshoot file. You can download it in System > Administration > Download Troubleshoot File.

Thank you. 

Regards,
Jerome

I had a similar issue previously, can you check that:

- /dev/ttyUSB1 exists: ls -al /dev/ttyUSB1
- if it is present can you execute cat /dev/ttyUSB1 you should be able to see incoming GPS frames
- and if that works try to change the first section of /etc/config/gps set it to :

config section 'gpsd'
        option galileo_sup '0'
        option glonass_sup '0'
        option beidou_sup '0'
        option enabled '1'

and restart gpsd ?

Regards,

I need some help! I think i can see incoming GPS frames, but i do not know how to change the config. I need instructions how to do it in the cli....

---

From the UI, go to Services->GPS->General disable Galileo NMEA Support, Glonass NMEA Support and Beidou NMEA Support

Save&Apply.

---

I am still getting the same results in cli as the screenshots say, when i type /etc/init.d/gpsd restart.

Is there anything else to get this now running after disabling these 3 options with only gps enabled?

---

Could you try a reboot ? The physical GPS subsystem looks okay the issue appears to be within ubus / gpsd.

Which firmware version do you use ?

---

The latest Version 7.01.4 as you can see in the first screenshot....

i already tried a reboot but shouldn't i get other response from /etc/init.d/gpsd restart ?

---

Is there some older firmware available that did not have that problem or is the hardware different in revision 0808 ??

---

The hardware subsystem must be fine for cat /dev/ttyUSB1 to output GPS frames. The issue is somewhere within the configuration file. Try disabling everything except GPS itself (AVL, AVL IO HTTPS Geofencing NMEA forwarding / collecting ...)

The answer from gpsd is strange the device gpsd looks for is in fact a reference to /dev/ttyUSB1. What is the output of

ls -alR /sys/bus/usb/devices/3-1/3-1:1.1

The hardware is fine, the device hierarchy also. What is the output of /etc/init.d/gpsd restart now ? Of gpsctl -seix ?

From your TS file : https_tavl_rule is enabled, geofencing also. Disable both and retry.

I am here logged in my Wireless lan at home, maybe the location data is derived from there...

I can do further testing tomorrow, actually my van is parked inside my garage....

---

Something is misconfigured I have nothing in /sys/bus/usb/devices/3-1/3-1 either and my gpsd is fine. Or the error message is misleading ...

---

As gpsctl -seix gives the correct output gpsd must be fine, the error message must be misleading. I have the same ...

Can you see you position in Services->GPS->Map ? What is still failing ?

---

I can see the Position in the map, but that worked from the point i was connected with my wireless at home.....

---

Ok ls -d /sys/bus/usb/devices/$id/${id}*/tty?* /sys/bus/usb/devices/$id/${id}/tty/tty?* should have a 2>/dev/null added.

root@Teltonika-RUTX11:~#  ls -d /sys/bus/usb/devices/$id/${id}*/tty?*

If you press "Update Location" in Services->GPS->Maps, do yo see a timestamp change ?

---

yes, the timestamp changes

---

So the subsystem is working fine the location that appears is given by the GPS module. The timestamp also.

---

So it seems to work now!

It shows the correct position in the map....

can be excluded that it does not get the data from the cell towers for the position?

Why is the no Data in metrics / gps ?

Is this in your Systems too that there is no data??

And what did the commands in the cli do to make it work at last?

---

> can be excluded that it does not get the data from the cell towers for the position?

The data comes from the GPS module.

> And what did the commands in the cli do to make it work at last?

Nothing, the cause was option galileo_sub '1'. And maybe something within TAVL or geofencing if the configuration isn't complete.

> Why is the no Data in metrics / gps ?

No idea. Is the device stationary ?

> Is this in your Systems too that there is no data??

I have a different use-case, the RUTX is fixed I use the GPS subsystem only to have a reference timestamp if the router reboots and the mobile interface doesn't come up or doesn't come up fast enough for some unknown reason.

The device is not stationary it is built in my van.....
