I just got a Nano BLE Sense board. I have installed all the drivers and added the board in the IDE when I attempt to upload a sketch I get the following error. I am really not sure why it is creating a folder in MATLAB data. I tried to uninstall MATLAB and it is sill giving me the issue. Any help would be appreciated.
Please check your sketchbook location setting in the Arduino IDE. Its likely set to your MATLAB folder.
File -> Preferences -> [Settings]
This should be the folder where you have the sub folder with the sketches. When you select a new folder on that tab, the IDE will create a new subfolder called libraries. You will need to install the BLE libraries from the library manager again. They will end up in the libraries folder next to your project folder.
