Hello everyone, is it possible to share informations like a list of variables between an arduino nano ble and a computer/smarphone please? If yes, can you explain me how. Thank you very much.
Yes
I would recommend you have a look at the documentation and examples first.

The Arduino side is not simple but there are examples in the library and in the forum.
For smartphones there are generic BLE apps that you can download for iOS and Android. They will allow you the read and write data. This is mostly for debug and testing. If you want something specific you will need to write an app yourself.
Unfortunately, the support under Windows is not great. What I got working is using BLE from the web browser using the Web Bluetooth API, JavaScript and HTML5. Here are a few links I found useful.
