I understand from communication with your sales department that the range is 10 -20 meters depending on the antennae in laptop bluetooth. In on of your forums you mention 50 meters.
For my project will need about 30 meters of range. Will I be able to get this with a good bluetooth dongle (class 1)? http://www.gridconnect.com/bluetooth-usb.html?utm_source=google&utm_medium=cpc&utm_campaign=North+America&utm_term=bluetooth+usb+dongle+b&gclid=CL6dmuuDgK0CFQSFhwodwGurRg
Or do I need to have you quote me on the xbee / ez-robot setup?
