  • Click on the ACC tile for Assetto Corsa Competizione

  • Click on the ACC tile in the RS Dash app

  • Set the "IP Address" field to be the same as the "Device IP" value shown on the RS Dash app main screen (see screenshot below)

  • Set "Use Broadcast Mode" to "Unticked"

  • Set "Update Speed" to "15" (you can set this number higher if you experience telemetry lag)

  • Click "Start Transmitter"

  • Start Assetto Corsa Competizione on your PC and once you start racing you should see the telemetry on the device.

Assetto Corsa Competizione - Troubleshooting Tips

  • Note: You must be running Assetto Corsa Competizione on the same Windows PC that you are running the RS Transmitter application on. 

  • IMPORTANT: A number of Android devices have experienced issues with the telemetry data stopping during use, or starting and stopping intermittently. If you are experiencing this problem, please turn OFF the "Use Broadcast Mode" flag in the RS Transmitter. You must then make sure that the IP address you have entered in the IP Address field in the RS Transmitter matches the IP address shown when you first start the RS Dash app. 

  • IMPORTANT: Do NOT have Jumbo Frames / Jumbo Packets enabled on your PC's network adapter as this may cause a loss of telemetry in Multiplayer sessions or single player sessions with a reasonable number of opponents. The symptoms for this would be that the app works flawlessly when playing single player with no AI, but you lose telemetry when playing single or multiplayer sessions with a reasonable number of opponents. If you are unsure whether or not Jumbo Frames have been enabled, an article such as this explains how to enable it so can therefore also be used as a basis for how to check and disable it if required. The reason why jumbo frames usually does not work is that the hardware between your PC and the tablet/phone device you are using does not support it. For example a number of Wifi routers / access points do not support this feature and will therefore cut off the transmission once Jumbo Frames are sent from the PC (which occurs once you have a certain number of human or AI opponents in game as the amount of telemetry data that needs to be transmitted increases).

  • Verify that your device is connected to the same Wifi network as your PC and that you have specified the correct IP Address for your device in the IP Address field in the RS Transmitter application.

  • Perform the following steps to try and isolate where your issue may be
    1. If you start the app on the device without the transmitter running, it should show the message "Waiting for Transmitter Signal"
    2. If you then load the RS Transmitter on the PC and click "Start Transmitter", the app should change to say "Waiting for game to start.."
    3. If you then start Assetto Corsa Competizione, the app should change to the vehicle page by the time you start driving. 

    If it stays at step 1 "Waiting for Transmitter" then it means that your Wifi connection between the PC and device is not working or you have specified the wrong IP Address. You could try tick the "Use broadcast mode" checkbox on the transmitter screen to see if this fixes your problem however a very small percentage of Android devices may have problems with broadcast mode resulting in the telemetry feed stopping between the PC and device.
