Serial communication between wireless stick and gps

Hi,
These days I’m working with Wireless Stick connected to a GPS module (Goouuu tech gt-u7) to receive GPS coordinate but I don’t receive anything.
I’ve used both HarwareSerial and SoftwareSerial, but he doesn’t work.

Here the connection:
RX -> TX
TX -> RX
GND -> GND

That’s my code: https://pastebin.com/JzvjAYSV

The result is ever “No GPS detected: check wiring”.

Can somebody help me?

maybe this will help arduinos-rx-tx-ports
