Hello,
I have tried to connect Lego EV3 from Matlab via Bluetooth, however, Matlab showed the following error message.
Error using error Unable to load a message catalog 'legoev3io:build'. Please check the file location and format.
Error in legoev3 (line 185) error(message('legoev3io:build:Legoev3BluetoothFailed'));
I have tried to find any helpful answers, but, couldn't find yet. I have no problem when I tried to connect via USB cable, however, not Bluetooth.
It would be very much appreciated for any helpful solutions.
Thank you.

There have been known bluetooth connection issues with Lego EV3 on Mac OS, while USB always seems to work. Usually, this error occurs when MATLAB is unable to locate or open the message catalog file. Refer to the instructions below to resolve this error.
1) Check if the following file exists:
support_package_root_directory\resources\legoev3io\en\build.xml
Note: support_package_root_directory is the directory where the Legoev3 support package is installed. By default, it is C:\MATLAB\SupportPackages\<matlab_version>\ for R2016a and earlier releases. And for R2016b+, it is C:\ProgramData\MATLAB\SupportPackages\<matlab_version>
2) If the build.xml already exists, the error may be occurring because MATLAB is unable to open the build.xml file. In this case, launch MATLAB as administrator and try to connect to Legoev3.
