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.

$GPGGA,234055.526,0000.0000,N,00000.0000,E,0,00,0.0,M,0.0,M,0000*47
$GPGSA,A,1,1E
$GPRMC,234055.526,V,0000.0000,N,00000.0000,E,060415,N
74

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
