Title: Using a bluetooth device
Post by: macbook on June 22, 2009, 06:48:56 AM

Generally we use a bluetooth module in a bot to receive signals from a bluetooth device. Can we use a Bluetooth dongle (USB stick used in desktops) as a bluetooth receiver in my bot for receiving inputs from a bluetooth device?

how do you mean?
most of the time people who use bluetooth in their robots use something called a bluesmirf on the robot end and a normal dongle on the pc end. i don't think you can use two standard bluetooth dongles to do this.

No you cannot. AVR has a slave usb port, not a master. And bluetooth dongle need fair amount of code (driver) to work, Way to much for a microcontroller

Well, you can do it if you have a RS232 bluetooth (not USB).
