Hello, I need a little help. I want to send from LabVIEW to Arduino via serial port the string for example "ABC" and so on. The problem is that when I send the string from LabVIEW .......the Arduino do nothing. Sometimes shows some kind of sign. When I send the string via Visual Studio it works perfectly. Is there someone who can help me. I attached picture of vi and Arduino code Thank you very much. Arduino code.txt

The normal quick drop wire function worked for me (more or less). I selected the index, and I selected the bundle by name, then quick drop then CTRL+w and it wired it up. I thought maybe the shift modifier might be needed but in this case it wasn't. I also added a boolean terminal and it was left unwired. Windows 7 x64, LabVIEW 2015 SP1 32 bit.

Like this: (VI is saved in LV 2011... should work back to 2009... back to 8.2 if you rewrite the subVI.) Get Name of Class of Object.vi
