The software you would need to do this is called Flowcode or you can contact me via my website (001tech.co.uk) for quotes and I will make it for you.
by this we can send between laptop and pendrive ,but i want to exchange data between mobile phone having bluetoothYou could use a microcontroller with USB host support (such as the Microchip PIC24FJ64GB002).
1. Connect the pen drive to the PIC24 via USB host
2. connect a Bluetooth device such as WT12 to the PIC24
Bluegiga - WT12 Class 2 Bluetooth Module
the PIC24 can read the pen drive and send the information over Bluetooth to a laptop or other some Bluetooth enabled device.
Is that what you wish to do?
