|2.  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. "ROBOTC2" is the friendly name for the NXT.

|6.  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.
