[F1 games] Setup to broadcast data to multiple apps

How to use Sim Racing Telemetry and other apps at the same time with the F1 games serie.

This guide shows a configuration that allows the F1 games to send data to multiple telemetry/dashboard applications, allowing you to use Sim Racing Telemetry alongside other dashboard apps. This setup can also be used to send data from one PC to multiple mobile apps.

The problem

F1 games can be configured to send telemetry data to only one destination (the pair IP + Port). On most operating systems, only one software at a time can listen to a given communication port, making impossible to use more than one telemetry/dashboard application at a time.

UDP Relay/Proxy tools

The setup is based on using a UDP Relay Server (aka UDP Proxy Server) to receive data from the game and forward them to multiple destinations.

Instructions below have been verified on previous versions of F1 games using Codemasters Proxy Server[www.eksimracing.com], but similar instructions can be used with other similar tools like Sim Racing Proxy Server[www.eksimracing.com], SimHub Software[github.com], etc.

Configuration

At the moment SRT doesn't support the change of the listening UDP port for F1 games, so the trick is to configure both the game and the UDP relay server to use a non-default port:

1. configure the F1 game to send data to another port than 20777 (eg 20778);
   
2. configure the UDP relay server to receive data on the new configured port (e.g. 20778);
   
3. configure the other dashboard app to receive data on new ports (e.g. 20779);
   
4. configure the UDP relay server to forward data to the ports 20777 (used by SRT) and 20779 (used by the other app).

Using the options of the UDP relay server, you can configure it to support more apps and also to send data to multiple mobile devices. Please refer to the documentation of the used UDP relay server for the detailed instructions.

In future we'll add the option to SRT to use a non default port, this will simplify the above steps.

Thank you :-)

@McBoud Yes: you must simply install the UDP Relay Server on your PC (using port 20778), configure the game on PS4 to send data to your UDP Relay Server (using the IP of your PC and port 20778), then continue configuring the UDP Relay Server following the instructions above.

Does this work if Game on PS4 and apps on PC?
