Traccar GPS http post advice

Wed Sep 05, 2018 6:55 am

Hi Team,

I've got hAP ac2 which will live in my car together with 3G modem and a GPS receiver.
It's all configured, I have internet and VPN tunnel back to home, GPS data is also getting through.

Now I need to send the GPS data to the Traccar server.
There is a script on wiki:
Code: Select all
{
:global lat
:global lon
/system gps monitor once do={
:set $lat $("latitude")
:set $lon $("longitude")
}
tool fetch mode=http url="http://10.55.8.160/index.php" port=8080 http-method=post \
http-data=("{\"lat\":\"" . $lat . "\",\"lon\":\"" . $lon . "\"}") http-content-type="application/json"
:put ("{\"lat\":\"" . $lat . "\",\"lon\":\"" . $lon . "\"}")
}
The problem is that I need to send data in OsmAnd format, the syntax is very simple:
Code: Select all
http://demo.traccar.org:5055/?id=123456&lat={0}&lon={1}&timestamp={2}&hdop={3}&altitude={4}&speed={5}
id is fixed for the current device.

Can you please help to modify the original script?

Thank you so much!

:do {/tool fetch keep-result=no url=("http://demo.traccar.org:5055/\?id=123456&lat=" . $latitude . "&lon=" . $longitude . "&timestamp={2}&hdop={3}&altitude={4}&speed={5}")
} on-error={:log error message="Fetch failed..."}

The problem is that the values returned by the tik GPS are not in a decimal value.
You need the data in a decimal value to post to traccar. Same with altitude and speed. For those you need to remove m and km/h from the data.
Just tested with Postman and after converting the latitude and longtitude to decimal value it would post

When Mikrotik updates the GPS package and enables it to output the location data to a friendly format it should work fine without requiring a middleman server to translate the data.
Currently I use Particle Electrons to send location data to Traccar and it works great. However I would love to use the LtAP as well.

I've got a working script since last night.
Started working on it and took some code snips from other scripts, including a github page I've found to be very helpfull, and the script translates the coordinates - outputted by /gps monitor - to decimal coordinates.
I've uploaded the script to github, but will be making some changes.
The tracket ID is the same as the LTE IMEI address
I'll be experimenting with the date-time so that can also be uploaded to traccar.

The current variables that need be updated are:
Code: Select all
:local serverurl "demo5.traccar.org";
:local serverport "5055";
The script is located at

v6.44beta37 will have:

*) gps - added "coordinate-format" parameter (CLI only);

ddmm will be an option.

Sweet!
Is there some way of extracting or generating a datetime timestamp ?

Timestamp issue solved with a script from forum user adeeadee
viewtopic.php?t=75555

script updated with the addition of the datestamp and posting the datestamp to the Traccar server

Where is "cordinate format" in CLI ?
Under system/gps I can't find it. I use 6.44.beta50
