Connecting Two NXTs via Bluetooth Using the NXT's User Interface

1. Use the NXT user interface to select Bluetooth comands.
   
   
   The top left of the NXT LCD status display shows the bluetooth status..The leftmost icon is the BT symbol and indicates that BT is enabled on the NXT. The icon indicates that the NXT BT visibility is enabled -- if visibility is disabled, then the NXT will not respond to search commands from other BT devices. "Dick2" is the friendly nane for the NXT.
   
   
2. Then select the "Search" command and run the command.
   
   
   
3. Once search has been performed, you'll be presented with a menu of the NXTs that were found via Bluetooth. In this case, only a single item -- the device "Dick1" was found.
   
   
   
4. Select the target device for the connection from the search results -- i.e. "Dick1" -- and then select "Connect"
   
   
   
5. The NXT supports connections to up to three "slave" devices. You need to select the appropriate "slot" (1, 2, or 3) for the connection. Select an empty slot -- all three slots are empty in the following picture -- and hit the orange button.
   
   
   
6. The NXT screen will show "Connecting" as the connection is attempted. Depending on the settings on your NXT, you may be prompted for a password.
   
   
   
7. Once the connection is made, the status ICON will change to "<>". The ">" indicates that the NXT is connected to another BT device.
