If by wirelessly you mean via Wi-Fi network then one convenient option is qrcp. It generates a QR-code right in your terminal, which you can scan with a phone and send/receive files through a web interface on the URL it provides.
If you want to transfer files regularly, there is another option. Almost every distro has Python installed, and the Python has a “built-in” FTP server.
You need to just cd
into desired directory and run the command python -m pyftpdlib -w
. It will open a FTP server with root in this directory.
You then can access it through a file manager, like Material Files for example, and send files and folders back and forth. In Material Files you can save the server address for future use.
Check out “Keys to Drawing” book by Bert Dodson. It gives a good versatile introduction without unnecessary ‘academic drawing’ pressure.
