Hi everyone ! I am using R2012b on Windows 10. I was willing to detect the Bluetooth devices around with the function instrhwinfo('Bluetooth') but I got this error :
instrhwinfo('Bluetooth')
Error using instrhwinfo (line 195)
Java exception occurred:
java.lang.NullPointerException
at
com.mathworks.toolbox.instrument.BluetoothDiscovery.discoverDevices(BluetoothDiscovery.java:448
at
com.mathworks.toolbox.instrument.BluetoothDiscovery.hardwareInfo(BluetoothDiscovery.java:247)
Any idea ? When I try the exact same function on Windows 7 I get the info I want.
Thanks in advance for your answer !

If I remember correctly, only R2015a and later versions are supported on Windows 10.
See the Platform Road Map for the MATLAB and Simulink Product Families for details.
Do not install Windows 10 on your Windows 7 computer!

Yes I know but yet my other codes/programs are well working on this version of Matlab with Windows 10
(Don't worry, I won't install W10 on my W7 computer !)

It’s probably time to Contact Support.
I still have Win 7 running on my 2009 HP laptop (originally came with Vista). No plans to ‘downgrade’ it either!
