Good day everyone! I'm into study about making a USB File-to-File Transfer Module in which you can transfer file instantly. I would like to have it Bluetooth accessibility and a Touch screen user interface. But I have no idea how to start with it. The module must be smaller as possible. All of the people I've asked for said that the Raspberry Pi product will be useful. Then, I would like to configure as, like, you can choose whether to transfer to the file to a Bluetooth device or to the output/input usb interchangeably so it does. Any idea? Thank you. God bless everyone!
1. It's primary function is to transfer file from a USB Mass Storage Device to another USB Mass Storage Device without the use of a netbook PC or something. Through this touchscreen and handy module, you can transfer files through the port-to-port connection or via bluetooth. (same principle as you were using a pc copying files from a flash drive to another flash drive)
IT CAN COPY: A. from the input usb device to another usb device (output usb) or interchangeably; B. from the input usb device to a bluetooth device via bluetooth option.
2. It must also be in touchscreen user interface.
So, that's it. I think it really needs a usb card or something, touchscreen and a bluetooth device right. and it will take a lot of programming.
I think this will help you to understand more, there's already an existing device. but it;s controls are just buttons and the all the files on a mass storage device are copied (everything) into another device. (i want this module to have the user the capability of choosing the file it wishes to send)
