I will try it with v22. Mine is currently 1.01.
There is still nothing on the serial monitor. I downloaded v22, uploaded the exact code from the tutorial, hooked up the TTL output of the GPS to pin D0, but nothing showed up after several minutes on the monitor. Using the voltmeter, I can see that the voltage is going up to 3.3v each second, so I do not see how this isn't showing up on the serial monitor.
