i want to use a usb bluetooth (dongle)..

so you have to implement the USB on the 8051 or.. the better way is.. use AT43USB380 - 8051 with onchip USB interface.
After that you need to write drivers for the usb dongle.
it will be better if you use a bluetooth module and interface it with your 8051. try searching on google for "Bluetooth Modules"
 Shams like this.

dear do u have any idea about the price and availability in India of AT43USB380 .also DS621 ,1620
Wed Aug 15 2007, 09:30 PM
Supplier: RS Components, India
Part: DS1621
Price: Rs.359.00
RS Stock No. 218-3826

Part: DS1620
Price: Rs.554.00
RS Stock No. 218-3810

Supplier: Digi-key

AT43USB380 is not available in Indian market, because not used too much. You can get it on special order form other suppliers, in bulk they are cheap.

hello ajay sir..
if i hav a bluetooth dongle(usb).. and i want to control microcontroller8051 from computer using another bluetooth dongle(usb)connected with computer... wht do i need to do?
Thu Aug 16 2007, 01:09 PM
well i must not recommend doing that.. because.. there are many things that you need to do... and which are certainly tough for an 8-bit controller to do..
like you need to write device driver to read and write data to and from bluetooth dongle, you need to write special code for pairing of PC with the bluetooth dongle. A permanent paring password might also need to be setup.
and on the PC side.. you have to write a special software just to read and interpret the data in correct form after receiving data from the dongle connected to PC USB.

So this is certainly not a good idea. Why don't you try looking for a bluetooth module for microcontrollers.. that is best option i guess.

ohk.. is ther any other way to control 8051 thor' computer without using wires... i mean wireless communication...Instead of bluetooth wht thing i can use... ?
