Bluetooth connection will work with most (but not all) bluetooth devices. So, if you want to be on the safe side, you will have to use the 32-bit version of KLOTS on your 64-bit machine.**

163	163	When the KLOTS perspective is activated, Embedded Java files //(.java)// will be automatically associated with the //KLOTS Editor//. To open an Embedded Java file simply double-click on it. The KLOTS Editor offers the full functionality of the //standard Eclipse Java Editor// as well as means to build, download and execute Embedded Java programs on the NXT brick. The easiest way to check if a file is displayed in the KLOTS Editor is to look at the editor's toolbar. There should be four new buttons.
