Bluetooth connection between Lego Mindstorms NXT and MATLAB

I am following the steps of the page: http://au.mathworks.com/help/instrument/examples/communicating-with-the-lego-mindstorms-nxt-brick-over-bluetooth.html. However, after pairing the device, matlab returns the error: Error using instrhwinfo (line 191) Bluetooth is not supported in MAC OS Mountain Lion (10.8) and higher Does it mean that there is no way that I can do the connection? Thanks.

The Bluetooth interface is supported on these platforms:
* Mac OS 10.7 and earlier versions only 64-bit
* Microsoft® Windows® 32-bit
* Microsoft Windows 64-bit
I have no information on the reason for this restriction, so I do not know how difficult it would be to create your own Bluetooth interface. You will not be able to use the prebuilt support, though.

Oh, so there is really no way of doing it. I would like to know the reason why is not being supported anymore. Thank you, anyway.
Sorry, I do not seem to find any information about why the restriction exists.
As of R2016a Mac OS X 10.10 and newer is also supported. It is recommended to use OS X 10.11 or higher.

MAC OSX Mountain Lion 10.8 is fully supported with MATLAB starting release R2012b.
Since you are facing issues with communicating with NXT over bluetooth using MATLAB on Mac OS X 10.8, please make sure that you have installed X11 on your computer by following the steps mentioned in the following article.

Sriram, thanks for your answer. I already have the last X11 installed and my matlab version is 2014b. I am just entering the command: bluetoothDevices = instrhwinfo('Bluetooth') And it gives me the error: Error using instrhwinfo (line 191) Bluetooth is not supported in MAC OS Mountain Lion (10.8) and higher
