Invalid data from GPS PMB688 parallax module

i’m currently dealing with the PMB688 module. I was able to get the correct date and time but no satellite was detected. It always show invalid data therefore I can’t get any longitude and latitude information. I’m a newbie to GPS module.

This is the example data that I got.


As attached is the sample code that I use. I found it from some website.

The "V" means that not enough satellites are in view to calculate your position. If you are not outdoors, with a clear view of the sky, then that is where you need to be. You may have to wait up to 15 minutes for a "cold start" fix*.*

Thanks a lot for your help. i try out by putting it under the sky view for 10 mins and it works
