Hello all,
is it possible to connect a Bluetooth device like the following with the Arduino board?
Thanks for your help... 
If you want to plug in the usb dongle to the arduino - you are going to need some USB host electronics and some libraries to drive it. (Arduino USB Host Shield | Hackaday)
Or, check out the Arduino BT - it has some of the bluetooth functionality you may need built in.

;D ;D ;D I was also thinking about this with my Arduino Nano 
it has usb-mini... - thought i just use the USB to USB-MINI adapter with small bluetooth adapter... but unfortunately it is more complicated :-[
