…does not provide valid data

Show us the output that is not what you expected. Copy the text from the Serial Monitor window, and paste it into your post, in code tags

 so it looks like
this.

Select what you pasted into your post (highlight blue) and press the “</>” button in the upper left corner of the post editor. It will add
** **[code]** **
and
** **[/code]** **
around the highlighted text. When you press Preview, it will appear in the white code block.

ever-changing data every few times. (ex. Latitude first = -7.68765 then Latitude second = -7.68778)

That is how GPS devices work. There is always some “jitter” in the GPS data, because there is always a little error in the calculations. There will be more error if the GPS device does not have good reception. The error is reduced when the GPS device has good reception to more satellites. There may be no location if the GPS device is not able to see any satellites.

If you are indoors, move closer to a window. If that doesn’t help, you may have to go outside.
