The 'Connect to the Computer' feature has been removed from all versions MATLAB. You can instead connect to the MathWorks Cloud and upload the files created on your device and access the files already uploaded to the MATLAB Drive.
The following URL can be used for connecting to the MathWorks Cloud from MATLAB Mobile:
The reason to do this is, the usage of the desktop connection was very low and we decided to focus new feature development in the cloud connection. Streaming sensor data to the desktop is still possible using the new workflow.
We would like to know your use case for the desktop connection. We might be able to offer an alternative using MATLAB Mobile connected to the cloud.
