  In order to be able to download and execute Embedded Java programs, the leJOS NXJ firmware should be installed on your NXT brick. KLOTS provides an easy firmware flash feature. To install the leJOS NXJ firmware connect the NXT with the computer via USB and turn it on. Then select //Window->Preferences->KIELER->Lego execution->Firmware flash// and follow the instructions. You do not need to set the NXT brick in firmware-update mode, although doing so may help in case you are getting errors during the flash procedure. The whole process should not take more than a minute and after that the new firmware is permanently saved on the NXT's flash memory, so that the original Lego firmware is fully removed. If you want to remove the leJOS NXJ firmware and switch back to the original Lego firmware, you have to flash it on the NXT brick. More information on how to do so can be found on the [[Lego Mindstorms website>>url:http://mindstorms.lego.com/en-us/support/default.aspx||shape="rect" class="ext-link"]].

  Next you must specify how KLOTS shall communicate with the NXT brick. There are two possible options: communication via USB or communication via Bluetooth. Select //Window->Preferences->KIELER->Lego execution// and choose your favored connection type. In addition you can specify the brick's hardware address or friendly name. To save you all the manual selections, you can simply click on the //Search for NXTs// button and then choose your NXT from the list of found bricks. Note that for establishing Bluetooth connection, your NXT and computer should be already paired. The pairing procedure may vary with different operating systems and Bluetooth stacks. However you should always initiate it from the computer, not from the NXT brick. The default NXT PIN for the Bluetooth connection is set to **1234**.
