interfacing of bluetooth with controller

Thanx farzad but my query was not regarding distance. USB dongle bluetooth devices available in computer shops work well under home enviornment but is this true for hazardous high temperature and humidity also.

bluetooth microchip pic

Guys I already try using a bluetooth dongle interfacing in a PC. My project is electronic billboard via bluetooth. Which is PC based I done it, late 2006. It mostly programming basics and circuit analysis on how you sent data to the serial port.

Using a nokia cellphone, we have NOTES their. We can sent it thru bluetooth, and receive by bluetooth dongle in the PC. Notes can be converted so that we can sent routine to the port bit by bit.

rgds,

cheap bcm2045 pairing

Hi bryan!

Can you clarify your last post? Your bluetooth dongle is connected to the PC through USB, right? Then you send data from your nokia cellphone through bluetooth to the PC?

Thanks

dear niket

would you mind to change your concept?
If not u can use the nRF24 which has built in MCU with Blue tooth.

let me know your plan

thanks for sharing

bt dongle mcu

hai i also working on that interfacing broadcom Dongle to PIC 18F4550..
if any details how the dongle communicates with the USB
we can develop that in micro -- need to study HCI Commands

Added after 22 minutes:

here is the hci spec from bluetooth.org

i think many of the USB dongles are working with BCM2045 i got it from local shop here is the datasheet..
and HCI standard Manual

bluetooth usb dongle code for microcontroller

Has anyone finished this app? I think it is hard to interface USB devices to micros, it jus sucks.

Get an RS232 bluetooth dongle, much better.

usb demo board bluetooth

Hi people.
Did someone make it?
I'm trying exactly the same thing for my graduation project.
I have two options:
USB<->serial<->low cost microprocessor or
low cost bt dongle<->usb host controller<->microprocessor with bluetooth stack.

I will try the second one. If someone already made something like this please share the secrets.

Geek regards.

This would be perfect except that it is class 2 so range is limited if it was class 1 it would have been so nice.
