Hi

I want to use an arduino nano 3.0, I download the Supported Package for Arduino and i found the main problem is the CH340 chip that mi arduino uses. It chip cannot handle baudrate greater than 230400 (matlab uses 921600), so I have to change the baude rate less than this value.

I found two ways to do it, but unfortunately none works.

a) find in the path C:\MATLAB\SupportPackages\R2015a\arduinoio\toolbox\matlab\hardware\supportpackages\arduinoio\+arduinoio\+internal the field calls boards.xml and change the value of the baude rate, but I haven't this file in my download Packag

b) Change de baude rate using this comma

>> ccodertarget.arduinobase.registry.setBaudRate(gcs)

But I cannot understand how can i use it. Because if I set this command in my terminal (MATLAB) and errors appears: Unable to resolve the name codertarget.arduainobase.registry.setBaudRate

I read the information there:
