Arduino / Firefly Port COM4 Problem

by Ukendt Kunstner

Dec 16, 2016

Hi ! 

I' m trying to read the data from Arduino LDR/Servo Code and I want to import it to the Grasshopper. But "Open Port" command doesn't allow me to. Following error pops up: "1. Solution exception:Access to the port 'COM4' is denied."

I' ve already checked the port configurations both from device manager and Arduino itself, but I couldn't solve it. 

I am attaching an image where I show the situation. Any help would be much appreciated :) 

Cheers!

      COM port issues with Arduino and Firefly are often caused by driver conflicts, incorrect port selection, or another application already using the connection. Checking Device Manager and testing with the Arduino IDE alone can help narrow things down. Similar communication troubleshooting is common when integrating devices like XR2211ID into custom projects.
