Hi Sirawat, I understand that you are encountering an issue with the `ArduinoPrefDirFolderName` property for the `arduino.setup.internal.TestConnectionScreen` class. A potential solution to this problem is to use MATLAB R2023b. The issue does not occur in MATLAB R2023b, so you can consider using this version as a temporary workaround. Hope this helps!

Hi,

Here are a few things you can try:

• Ensure the COM Port is free and available. Close any other applications using this Arduino board and verify that you can see the COM port in Device Manager.
• Restart the hardware setup process by executing the arduinosetup command in the MATLAB terminal.
• Follow the hardware setup screens.

If you still encounter the same error, execute the following command in the MATLAB terminal and confirm that you can create an Arduino object:

a = arduino("COM9", "Mega2560", "Libraries", {"I2C", "SPI", "Servo"}, "ForceBuildOn", true)

If you can execute this command without any issues, please proceed with your workflows.

If you encounter any errors, share all these results with us by contacting our technical support team:
