[Free][Windows only] UE4Duino 2 - Arduino (COM port) communication

Srry for using the word Bug, but i’m with this for like 6 hours and i don’t know what to do, here’s my ue4 code



Event Tick -> isValid? -> Print (snd) -> Delay(0.1) -> Read Line -> Print String
(Arduino)----------|--------------|---------------------------|


Event BeginPlay -> Open Serial Port -> Branch(True) -> Set Arduino -> Set WriteLineEnd

Event End Play -> isValid? -> ClosePort
(Arduino)--------------------------|
