Hi,
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.

Try setting the variable arduinoio.IDERoot to an address which the user has access to write and read
For Example:
arduinoio.IDERoot = 'C:\\Program Files\\Arduino'
or
Try running MATLAB as admin

I am getting following after running following script; my USB port: 'COM3' and Arduino Hardware: 'Grove Beginner Kit for Arduino'.
Exception creating support package: C:\ProgramData\MATLAB\SupportPackages\R2020b\help\supportpkg\arduinoio\doccenter.properties does not contain the baseshortname entry.
>> a = arduino('/dev/cu.usbserial-0001','Uno');
Unable to find Arduino hardware at /dev/cu.usbserial-0001. First argument must be a valid serial port, Bluetooth address/name or IP address/hostname.
What wrong I am doing? Please help
