Hello! I am trying to get my Arduino Uno Wifi Rev 2 to communicate with labVIEW 2020SP1. When I go through the firmware wizard and open the blink example, it outputs an error (below) and the RX LED blinks in yellow rapidly. "Error 5003 occurred at : Open Serial.vi >> Initialize.vi >> Initialize Device.vi >> Synchronize.vi LabVIEW was unable to connect to the LINX device using the following settings: Interface: Serial COM Port: COM3" I'm not really sure what to check next. I made sure there are no other open connections to the Arduino Uno Wifi and I have Diligent LINX and LabVIEW Interface for Arduino packages installed. Any advice is appreciated!

LINX blink example error 5003 using Arduino Uno Rev 2

I installed the NI LabVIEW LINX Toolkit for LabVIEW 2020SP1 (32-bit) [I have RT2020SP1 (32-bit) installed as well], but I am getting the same error. I also uninstalled Digilent LINX.

Thank you,

Jamie

Unfortunately, I have not used the Arduino Uno So I can't provide any more details on your issue but you are now using the correct version of software.
