Arduino with 2019b connection issues

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.

Answer 1

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

Answer 2

[Tafazzal Hoque]

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
