I got error when I try to connect firefly to arduino.
My arduino connection can work normally without firefly.
When I use READ UNO function, it got an Error, I guess this error in English is NullReferenceException.
When I use WRITE UNO function, it seems that when I change DATA in firefly, the “RX” light in arduino board is flashing. But nothing change with arduino’s connections (connecting is correct).
And I’ve change in both computer, still got the same Error.
