Does anyone know the technical requirements for a cell phone that will be communicating with an NXT? That information is not up yet on the MindStorms Bluetooth webpage. Will most phones with Bluetooth capability work with the NXT? Thanks, David (18 years ago, 23-Aug-06, to lugnet.robotics.nxt)

It seems the goal of this first event is to get some basic BT communication working, and if there's time, actually try a swarm-like experiment. If anything else, it (...)
