■Software Errors

• Could not access to Studuino Serial port already in use. Try quitting any programs that may be using it.

• If you're using our Scratch 3.0-based software on Windows, using Transfer for the first time after starting the software may cause this error.
  ●Solution

  • Try using Connect first. Both the Connect and Transfer features should then work normally.

• If using Windows, double-check to make sure you have the correct device driver installed.
  ●Solution

  • Click here to download the installation guide and follow along to install the correct driver.

• You will also see this message when there is a communication error between your PC and Studuino.
  ●Solution

  • Disconnect and reconnect the USB cable to your PC.
