    NXT Ultrasonic reporting wrong values —Patrick J. Levy
   A just get my NXT, and everything works fine, but the ultrasonic sensor is not reporting correct values.

        Re: NXT Ultrasonic reporting wrong values —Brian Davis
     (...) I'm not sure what you mean by "completely stopped" - stationary? I suppose it's possible that you actually have a bad US sensor.

         Re: NXT Ultrasonic reporting wrong values —Patrick J. Levy
      (...) Yes, "stationary" is the correct word... The problem that i bought this one in UK, but i live in Brazil.

     (...) No, is not. I am in "desperate mode", so, by now I am using only the NXT brick and the US, and trying to figure out more information about this condition... I realize now that the black grid in front of the right "eye" of the sensor is turned (...) (18 years ago, 15-Oct-06, to lugnet.robotics.nxt)
    
         Re: NXT Ultrasonic reporting wrong values —Steve Hassenplug
     (...) I don't think that's an issue. In the sensors I have the mesh is not straight. Steve (18 years ago, 15-Oct-06, to lugnet.robotics.nxt)
   
        Re: NXT Ultrasonic reporting wrong values —Patrick J. Levy
   (...) What I discover just now: If I press the light gray conector case behind the sensor case with my nail, it will report the correct values!! but when I release, it stop working again.
