I have recently updated to 2019b and cannot use my Arduino Uno anymore with Matlab (macOS Catalina). The error message I'm getting is pretty generic,
a = arduino('/dev/tty.usbmodem14101','Uno');
Updating server code on board Uno (/dev/tty.usbmodem14101). This may take a few minutes.
Cannot program board Uno (/dev/tty.usbmodem14101). Please make sure the board is supported and the port and board type are correct. For more
information, see Arduino Hardware Troubleshooting.
I have no idea how to even begin debugging this, any help would be appericiated.
