Starting and connecting

If you want to use SmartRace with a Carrera Digital track, please first make sure that all requirements are met. If you want to use SmartRace on an analog track, please take a look at this section of the manual instead.


  • A Carrera Control Unit must be installed in your track.
  • The Carrera AppConnect bluetooth adapter must be plugged into the control unit. Attention: You must not connect a Carrera lap counter at the same time, otherwise errors may occur.
  • SmartRace must run on a tablet, smartphone or Mac that has at least Bluetooth 4.0. This should normally be the case for all devices built within the last 10 years.


First make sure that Bluetooth is activated on your device (tablet/smartphone/Mac) and the control unit is switched on. If the AppConnect adapter is connected correctly, the integrated LED flashes blue. Now start SmartRace on your device. As soon as the app has been started, the connection to the Control Unit is automatically established. If no connection is established, you can find out why here.

Note: when connecting the app to the control unit, a START signal is sent to the control unit for technical reasons. This may cause driving mode to be interrupted and all LEDs on the control unit to light up red. In this case, simply press the ESC or START button once to resume driving mode.

A green bar should indicate that the connection has been established. In principle, you can now start immediately. If you now cross the finish line with a car, “Unassigned” will be displayed on the race screen as the driver and car name. This indicates that no driver or car has yet been assigned to the controller used for the car. You can find out how to do this here. If you have not yet created any drivers or vehicles, you can find out how to do this here.

SmartRace is a software for Mac, tablets and smartphones and is used for timing Carrera Digital tracks in 1:32 and 1:24 scale and via the Analogue mode also for analogue tracks (e.g. Carrera Evolution, Carrera Exclusiv, Carrera Go!!!, Ninco, Scalextric or others). SmartRace either connects to the Carrera AppConnect adapter via Bluetooth or takes the measurement in analogue mode via the camera of a smartphone connected via SmartRace Connect
