Hi Emmanuel, The purpose of BTRespond is to reply to commands sent from iCommand. You run BTRespond on your NXT brick, then run an iCommand program to control motors and read sensors. So far we only have working commands for motors and sensors but the full Lego Communications Protocol is on the way.
