Hi @patmolloy,
Sorry for the delay in my response. The only issue I noticed in your code is the usage of the seconds parameter with your hub.set request. You can remove that entirely.
On the GPS side of things, there a couple of things to note. If you are using the onboard antennas of the Notecarrier-AF, it can take a minute or so to acquire a good signal from the GPS satellites. So even though it’s in continuous mode, that doesn’t mean you’ll see a signal immediately. Also, you almost need to be outside with a clear view of the sky (indoor GPS generally requires an external antenna). I also find it easier to test in the browser at https://dev.blues.io (issuing the card.location.mode and card.location requests) vs jumping right into the Arduino IDE.
One last thing: make sure you’re on the latest firmware in case you haven’t upgraded recently!
