Design Module For Data Transfer Between Bluetooth Device And Flash Drive Using USB Host Controller

Abstract

In the modern world no one can refuse the popularity of UNIVERSAL SERIAL
BUS (USB) storage device. Drawback of USB device is that being a peripheral device, it needs a
host usually a PC to initiate and mediate communications between two USB stora ge devices.
This module provides the platform such that two USB can communicate directly without PC.
This module uses a chip named as VDIP2 embed with VNC1L host controller further interfaced
to microcontroller. USB device directly connected to the port on VDIP2 chip. When USB is
inserted into the port then VDIP2 sends a signal to microcontroller to inform that first USB
inserted. Then controller waits for signal from other port. After the reception of signal controller
is ready to transfer the data between USB’s. There is also a Bluetooth module that enables the
module to connect with any wireless device such as mobile, laptop. With the help of this
Bluetooth module device is able to send data wirelessly. Data can be transfer in either direction
from USB device to Bluetooth device or from Bluetooth device to USB device. Only controller
can get the input from the external hard key from the user, once the user press the hard key then
controller gets the information to transfer the data between two USB devices or with Bluetooth
Device. For the interaction of user there is keypad and graphical LCD. User can select the
appropriate operation from options with the help of keypad.
