Hi guys,
I have a very strange problem.
I made a class to encapsulate the Adafruit_GPS (https://github.com/adafruit/Adafruit-GPS-Library/blob/master/Adafruit_GPS.cpp) library to abstract from other parts of the code to a possible change of GPS.
So I make the call to class, which creates the object using the class of Adafruit_GPS Serial1.
Until then OK, it works. The problem happens when I turn off the board completely and turn on again.
The Code is considering the Serial1 is a SW, not HW. (Line 252-269 of their library.)

Serial.println("Comecando!!!!");
gps = new GPSClass(5,20);
gps->on();
gps->begin(&Serial1);
gps->start();
}
void loop() {
gps->getData();
gps->show();

}
I removed some parts of the code. Maybe I have deleted a funcção or other unintentionally. If you feel a lack of something, let me know.
But as I said the problem is happening when I unplug the board and again I reconnect. I never saw it and I have not found much help on the internet …
I thank anyone who can help.
Thank you
Sorry for my poor english …
