I have this problem when connecting arduino with linx, I tried to disable the ports and use VI to close the VISA sessions but it didn't work.

This means the port is opened in some other program...

[RobertoSV]

do you know a way to close the ports?

[Albert.Geven]

maybe you still have your arduino environment open, that is blocking the port for other programs

[RobertoSV]

It's not open, but I'll try to uninstall it, thanks.

[Albert.Geven]

Uninstalling is not needed. Just close aal other programs that may have that port open.

Even MAX!

[RobertoSV]

Everything is closed, just LabVIEW is open.

hi

Is it possible to share your code?

Just attach to the mail.

Maybe a race condition is generating an error

[RobertoSV]

[Albert.Geven]

I don't see a race condition in these pictures.

Please attach the vi or give the name of the example.
