I don’t know if this is a bug or not. I’ve just put Cayenne on a Raspberry Pi with recent full Raspbian. If I go to the GPIO page in a PC browser I can turn ports on and off, but the tab for that in the Android App, changing the state of the same GPIO pins, I just get a red rotating BUSY. Not a good start…
thank you sir, for reporting this. team will work on it and have it solved soon.
