Custom URL - Parameter %SPD sends a wrong knot speed value about gpslogger

[mendhak]

Sorry for the late reply. I'm not sure where you are seeing knots? If you mean the imperial units, that should be displaying feet per second (the code just converts meter to feet) but important to note that's only for display purposes. All values are in SI so the value being sent is meter/second.

Thank you for your reply and I also apologize for taking so long to give you some feedback.
Your answer makes sense and I confirm your statement as I've controlled the content of the data sent to my Traccar server and converting them does perfectly fit to a speed expressed in meter/second.

To give you more insight about why I'm talking about knots speed, this is because the Traccar server application I'm using is usually managing raw data coming from NMEA sentences spit by GPS devices.
In order to have the application compliant with a majority of solution, it uses the minimal information that could be retreived from GNSS devices and usually the common speed information available in all GNNS variant is the ground speed expressed in Knots instead of regular speed units (m/s, km/h, etc...).

The issue I'm facing now is clearly explained by another Traccar user in this forum post.

I've dropped a support request in the same topic as it seems the issue can be managed by playing with some configuration file.
If you're OK, I'll close this topic if I receive no answer in the next 30 days or if I eventually find a solution in this expected delay.
Do you agree with that?

Thank you again for your kind attention.

Replying to myself.

My issue is in fact handled by my Traccar web server system.
It has a specific setting to manage data expressed in m/s to be displayed in km/h, but it isn't document, explaining why I wasn't able to find it by myself.
After applying the modification in my server configuration file, everything is now working perfectly.

Thank you for the attention you shared on this topic.
It can be closed without issue.
