I wanted to use the bluetooth board for a wireless project but it seem the distance range is not large enough. The computer stops receving data after 10 meters and a closed door. I need to send data from about 20 meters and through a brick wall. Is this possible? Is there any way to amplify the bt signal? What to do... Any help appreciated!
I've read somewhere the BT could have a range of 100 meter (http://tinker.it/now/2007/01/13/the-arduino-bluetooth-board/).
