NEO-6M GPS module can not catch the fix...

I have a problem with the NEO-6M GPS module.

The module can not catch the fix. I even replaced a standard antenna on the BS-580

and then... nothing ... for an hour everything is outside the window, and after that time I have readings from the u-center as on the screen.

Any idea?

I will add that the SIM800 module caught the fix after 5 minutes even inside the room ....

So what happens when you take the GPS outside ?

Those are not very strong signals, so you do need to see if it gets a fix when the signals are better.

Did you buy the GPS from a reputable supplier or was it cheap on eBay ?
