Does this normally happen when you are downloading firmware to the NXT brick, when downloading a program to the NXT, or at another point in the setup process? I believe this is a normal message that appears when the NXT is put into boot mode for firmware downloading (I can confirm this tomorrow once I'm back in the office). If you are able to, please feel free to upload a screenshot of the message as well as this will help us determine if there is an issue or not.
Also, setting up an NXT brick with a Bluetooth connection can sometimes be a tricky matter. I always recommend taking a look at the 'Setting up Bluetooth for the NXT
' guide on the ROBOTC wiki as a quick, handy reference guide in the meantime.
