When I received the Sparkfun Blynk Board, the QR code that came along with it was not working. Every time I scanned the QR code it says that it was not a valid QR code. I’m not sure if the QR code expired or, if it wasn’t working in the first place. Help…
This happened to me once. Are you connected to the internet? (and not your board wifi). I noticed I got this error when I was connected to my Blynkboard’s wifi network which doesn’t have an internet connection but when I went back to my home wifi network then it scanned just fine. That or your cellular.
