I’ve got the Asset Tracker v2 with an external active antenna. I’m asking it to report coordenates every 30 seconds since it is on a moving object I wish to track down.
It got a fix, inaccurate by 100m, and after that I’ve moved the object but it still reports the same coordenates.
Am I missing something?
Thanks!

I changed part of the Asset Tracker code to force GPS updates if the old position was past a certain time limit.

> @rickkas7 I got everything working on the i2c bus using your Asset Tracker library slight_smile It’s nice to have a quality Accelerometer to add to my box of tools. I did notice one line that I think needs to be changed regarding the GPS positioning. In the GPS Wait State case you have if (gps.location.isValid()) { I noticed that the program would constantly use the previous GPS Fix location data even though it had zero satellites in view. If I would have moved the GPS unit it …

Great! Is “\<2000” in seconds or miliseconds? Thanks!

Milliseconds.

Let me know if that code snipped solves your problem. It did for me.
