I checked several answers for same question but none of them help.

I also changed the nano board and GPS module but without luck. I ran it outdoor.

This post question had same issue except my date does not display the correct date and time.

My connection:

vcc->5V
rxd->d4  
txd->d3  
gnd->gnd  

FullExample program from TinyGPS++, I get following types of entries

UPDATE:

I change the antenna. At some time I got this. From the GPGSV sentence I know that there are about 15 16 satellites in view but the FullExample only show 0.

My idea now is to supply external power for the DFRduino Nano

Any idea how I can continue. Should I changed to other type of gps module?

The ceramic antenna is the issue. I changed to the external 1.5GHz one. It got fix under 5 seconds
