Problem using opta on Arduino Cloud and PLC IDE

Official Hardware Opta
1

I am trying to follow the tutorial from the Arduino website: https://docs.arduino.cc/software/plc-ide/tutorials/plc-ide-cloud-support/.

I am using the Arduino OPTA WiFi AFX00002 model. Additionally, port I1 is declared as an analog input, where a variable DC voltage signal is connected.

When uploading the program from the tutorial using PLC IDE, it uploads successfully via the virtual COM port (COM10). However, the problem arises when trying to upload the program to Arduino Cloud, which uses the physical COM port (COM8). To perform the upload, the device disconnects from the virtual COM port in PLC IDE and remains connected to Arduino Cloud.

In other words, I cannot use both COM ports simultaneously, as both PLC IDE and Arduino Cloud attempt to use the same COM port.

Hello, I managed to solve it by updating all the libraries in Arduino IDE and downloading the latest version of Arduino PLC IDE.
