I am trying to make a GPS tracker using the GPS module NEO 6M. How can I create a code for the argon board to make this GPS tracker using the neo 6m GPS module? Please help and thanks.
It looks like that GNSS unit has a serial interface (defaults to 9600 baud) and should support the standard NEMA protocol.
I’d start with the AssetTrackerRK library which includes the TinyGPS++ NEMA parser, and also includes some support for u-blox extensions that you may or may not eventually need.

Thank you soo much for this, i have a question, is the following set up connected properly to use example number 1 from your library?
the goal is to make a gps tracker using the neo 6m module, should i add anything more to this set up using example number 1 from your library as the code for this circuit?
That looks correct.
I am not able to find particle.h when adding that library to my code using the particle web IDE
@tineframe11, Particle.h is “built-in” to the IDE and you don’t need to have the actual file to include it.
@tineframe11, are you compiling an example from the AssetTrackRK library and if so, which one?
Example 1. I will love to have this working for my argon board to make my GPS tracker using the NEO 6M module
@tineframe11, I am able to compile that example without any errors. Are you sure you have your Argon selected as the target (yellow star next to its name in the IDE).
i have my argon device connected, is there any way you can share a screenshot of it to see if i made any mistake?
Here is the code after i uploaded <TinyGPS++.h> and <AssetTrackerRK.h>
// This #include statement was automatically added by the Particle IDE.
#include <TinyGPS++.h>
// This #include statement was automatically added by the Particle IDE.
#include <AssetTrackerRK.h>
// only used for AssetTracker::antennaExternal
// Port of TinyGPS for the Particle AssetTracker

You need to remove TinyGPS++. There’s already a version in AssetTrackerRK and having two will cause that problem.
It didn’t remove properly. You may need to create a new project and only add AssetTrackerRK.
alright, thank you it finally compiled successfully now after flashing it where can i see results of the gps module sending location?
