We just installed a Bluetooth and it is wonderful.  We bought a Windows 7
compatible dongle
( for
less than $20 and it works with no connection problems to the NXT.  My team
has become fascinated with reading the sensors via Bluetooth while the robot
is roaming and have discovered that none of their reset rotation sensors or
reset motor blocks seem to be resetting anything.  They put these before the
wild turns and the turns still are wild.  On these turns, the robot behaves
for a time or two, goes on a wild turn  for a time or two and then go back
to behaving for a time or two.  However the team has noticed that when they
reset the turns manually via the Bluetooth at the start of the program, then
all of the turns behave fine.  Has anyone else experienced this?  Is there a
correct way to resetting rotation sensors and motor blocks other than just
dumping then in front of a turn?  How can they reset the turns without
manually going through the Bluetooth each time?


Thanks for any help that anyone can offer!
