Automatic telemetry

RaceFlow receives telemetry straight from the game over UDP. No SimHub, plugins or file exports needed.

Games: F1 25 / F1 26, Assetto Corsa Competizione and Automobilista 2.

Plan: requires Pro or higher (or the free trial). See Plans.

Caution

Doesn’t work on the web version: browsers don’t allow direct UDP communication. Use the Android or Windows app, on the same local network as the game (or the PC/console).

Set up

1. In the menu, open Auto Recording → Configure.
2. Choose the game and create a configuration.
3. Set the IP and port (see the scenarios below).
4. In the game, enable UDP telemetry with the same port.

In ACC, RaceFlow can adjust the game’s configuration automatically.

Network scenarios

RaceFlow and game on the same PC

• Use IP 127.0.0.1 (this very computer).
• The port can be any number between 1024 and 65535. F1 25 uses 20777 by default. Use the same number in RaceFlow and in the game.
• You do not need UDP broadcast mode.

RaceFlow and another app (e.g. SimHub) on the same PC

Only one app can listen on a port at a time. For both to receive:

1. In F1 25, go to Settings → Telemetry → UDP Telemetry.
2. Turn on UDP broadcast mode.
3. Use the same port in every app.

RaceFlow on Android and game on PC

The phone just needs to be on the same Wi-Fi network as the PC. The game sends over the network and the phone receives, with no cable or extra software.

Follow the session

Under Auto Recording → In progress you see the detected session. At the end, the result is recorded and posted to the league.
