This solution worked for the "Simple Test" sketch. I am now able to see location data in the serial monitor after following Pascaljedis advice.
My code for the setup section now loos like this:
"void setup()
{
// Added this
static const int RXPin = A1, TXPin = A0;
SerialMonitorInterface.begin(115200);
ss.begin(GPSBaud);
while (!SerialMonitorInterface && millis() < 5000); //On TinyScreen+/SAMD21 platform, this will wait until the Serial Monitor is opened or until 5 seconds has passed
SerialMonitorInterface.print("Simple TinyGPS library v. "); SerialMonitorInterface.println(TinyGPS::library_version());
SerialMonitorInterface.println("by Mikal Hart");
SerialMonitorInterface.println();
gpsInitPins();
delay(100);
SerialMonitorInterface.print("Attempting to wake GPS module.. ");
gpsOn();
SerialMonitorInterface.println("done.");
delay(100);
while (ss.available())ss.read();
}"
(NOTE: I added this: " static const int RXPin = A1, TXPin = A0;" to beginning of setup routine. The text between the quotation marks.
I hope this helps.
