Thx all, will try that.

For anyone else that gets stuck in the future, I just modified the TinyGPS++ example to work with it.

after uploading sketch these are the serial connections;
1.Disconnect console cable.
2. connect GPS (TX) -> ESP8266's (RX) - serial
3. Connect console cable (RX) to ESP8266 GPIO#2 (TX) - serial1 for debugging.
