Hi Dudu Arife,

The serial connection failure with Arduino Mega2560, Support Package for Arduino Hardware can be resolved by the below steps:

• Ensure that the Arduino IDE is closed as the Arduino IDE can sometimes lock the COM port and prevents MATLAB from accessing it.
• Open the Device Manager (on Windows) or System Information (on macOS) to check which COM port the Arduino is connected to.
• Ensure that the correct COM port is selected in MATLAB. You can specify the port explicitly using the “arduinosetup” function or the Hardware Setup screens.
• Ensure that the latest drivers for the Arduino Mega 2560 are installed. This can be done through the Arduino IDE or downloaded from the Arduino website.
• Use the “arduino” function with verbose output in MATLAB to get more detailed error messages:
• a = arduino('COMx', 'Mega2560', 'Trace', true);
• Replace COMx with the correct COM port for your Arduino.
