https://wiki.teltonika.lt/view/RUT955_GPS

or from CLI you can enable it by : gsmctl -A 'AT+QGPS=1'

for live view type grep /dev/gps or following the type of the gps sentence you can filter like this for example grep GPRMC /dev/gps

Why now when I check from putty with this syntact : gsmctl -A 'AT + QGPS = 1',
error appears on putty: + CME ERROR: 504, like that ...
Can you help me, sir?

by anonymous
I don't see /dev/gps on my teltonika even though I have GPS turned on and working

This means that the GPS is running in background,type grep /dev/gps and you will see data received.

by anonymous

yes all the methods you told me that I tried, but still failed: +CME ERROR:504

How and on what medium are you trying to read the gps data? Have you pointed it to a server to have the data sent?

Are you having trouble breaking the string down?
by anonymous
I tried reading gps data via CLI / putty sir ..

Yes sir, I'm having trouble breaking the string down sir, please your helping sir :|
by anonymous

Your example above shows the byte breakdown. You'll need to break down the string into appropriate bytes using software.

If you've never done it before, its not for the faint hearted.

by anonymous
How do you solve it with software, can you tell me sir?

Yes I have never done it before, so I get confused, but I really want to know and want to use rut955 ..

Can you give me the best solution sir?
by
It’s not something that will take 5 minutes mate. My advise would be to use something simple like nodered. Create an http tcp end point, then pull apart the string using JSON in a function node according to the Teltonika gps protocol.

I suggest you get googling.

Pay for RMS and view the RUT location via that.
