Arduino UNO Reboots when Serial Port is Closed/Opened by LabVIEW VISA on PC Side? | Arduino Compatible Compiler for LabVIEW Discussions | Forum

Hello:

I have the Arduino UNO programmed to read Encoder position via the count variable

I found out that the Arduino UNO Microcontroller stops running once LabVIEW closes or re-OPENS the VISA Serial COM Port. I can see this by looking at the returned Encoder counter value re-initializing each time I close and re-open the COM Port from the LabVIEW PC monitoring program.

Is there a way to have Arduino UNO continue to run and write to the Serial Port even if there is no listener or connection on the other end? This way Arduino UNO can run dedicated and send updated sensor status info when requested. In my case I can see that the Arduino UNO still has LEDS blinking after I turn off and close the Serial Port in LabVIEW software. But Somehow the program re-initializes after I open the port at a later time.

Note that for the case of Encoder counts, rebooting means that the Encoder position is lost and gets reset to 0.
