Now, I bought Ultimate GPS Logger Shield from Adafruit. Initially I loaded a 'blank' sketch into the Arduino
I am able to see the NEMA sentence perfectly.
This implies that the GPS is connected to the hardware serial pins.
SoftwareSerial mySerial(8, 7);
Adafruit_GPS GPS(&mySerial);
This implies that it is not.
Only one implication is correct. Which one?
