Wifi File Transfer need

Hello there,

can anyone help me with a .aia file of file transfer? I found something old .aia to test my projects but I got errors because of old extensions. I want an .aia that have two buttons. Send and receive. When the send button pressed you can choose a file and send it to someone generated by a qr code. The receiver read the qr code and receive it. Can you help me please? :slight_smile:
