So I've tried your code, and other codes, and nothing really seems to be working. At some points it seems like the above code is working because LED 13 is blinking, but whenever I pull up the serial monitor, LED 13 goes solid and nothing appears on the serial monitor. In general, the GPS LED is a solid red but whenever I try to get information out of it, it always fails. I'm at a lost at what to do. It might be a problem with the GPS TX cable or with something in the software. Does anyone have any suggestions?
