How do I get the NXT ultrasonic sensor to work in the Education EV3 Classroom application?

  • OK: I have connected a NXT ultrasonic sensor to the input port 1 of an EV3 control brick.
  • OK: For testing, one motor is connected to port B.
  • OK: In the EV3's "port view", I see that port 1 is reported as 1:NXT-US-CM.
  • OK: In the EV3's "port view", I see that port B is reported as B:L-MOTOR-DEG.
  • OK: A simple program in the EV3 Home Edition works: the motor turns according to the sensor output.
  • Problem: A simple program in the Education EV3 Classroom application does nothing. The application shows only the motor is connected. The ultrasonic sensor is not shown.

EV3 Classroom only supports LEGO EV3 sensors. It does not work with NXT or 3rd-party sensors.
