I doubt that this is specific to the Thing from Sparkfun I mention it just in case.
I’ve found that when I add a switch in the android app that controls the LED pin (5), the switch shows a reversed status. When the LED is on, the switch shows that it’s off and vice versa.
Actually, I did some additional testing and found that the Thing LED seems to be reversed. When I manually write HIGH to that pin, the LED goes out
@pamela_sparkfun might be the best person to answer
I also posted the question on their product page
the LED is wired that way (actually on a few boards like the ESP12E as well) so it allows you to share the pin as a button input as well as an LED output.
you can easily use a virtual pin to reverse the logic by yourself!
