@RikuShadow97 also, you could try printing lines from Arduino and using the read line function in Unreal. Then, your strings could be like: “variable1”, “50”. Then you can check if the string is the name of your variable and convert the next string to an Int. You can still very likely get just a piece of the data still, like “vari” and then “able1”, by reading before Arduino finishes writing. That’s why the protocol idea is still the best way.
