Hello,

Is there a mistake in my program? my read buffer did not show up. i attached my VI file for reference. I dont know what to do anymore. i use arduino uno with HC-SR04. Thank you!!!

How much data is your Arduino sending? At least 100 Chars within 10 seconds default time out I hope.

And did you specify an end character the default is LF (ASCII 10 decimal).

So if you used println it should work anyhow.

Or you have swapped the send and receive line of the rs232 connection?
