Connecting Assetto Corsa & Competizione

Assetto Corsa and Competizione are the two titles that need something installed, and it is worth knowing why: unlike Forza or F1, neither game can send live telemetry over a network at all. They only publish it inside Windows, on the PC running the game, where a phone cannot reach it. The Marque Telemetry Bridge is a small app that sits on that PC, reads what the game publishes, and forwards it to your phone.

Set it up

1. On your gaming PC, download the bridge from getmarque.club/download and double-click ACBridge.exe. There is nothing to configure and nothing to install.
2. Windows will warn you the first time. A blue “Windows protected your PC” box appears because the bridge is not code-signed yet. Click More info, then Run anyway. The download page lists the file’s SHA-256 if you would rather check it first.
3. If Windows Firewall asks, allow it on private networks. Without that it cannot reach your phone.
4. In Marque, open Record › Record a virtual drive and pick Assetto Corsa or Competizione. Leave that screen open - it is what the bridge is looking for.
5. Within a second or two the bridge prints ✓ Connected to Marque and the app says Bridge found on <your PC>. Nobody typed an address.
6. Tap Start, launch the game, and drive.

If two phones answer

The bridge asks the network “is there a Marque app out there?”, so in a household with two of them it can get two answers. It will not guess. Instead it stops and asks for a pair code - the four digits shown on the Virtual drive screen of the phone you actually want.

Type those four digits once and it remembers them; from then on nobody else’s phone even replies to it.

When the bridge cannot find your phone

Some networks block devices from discovering each other - guest Wi-Fi with client isolation, a “Public” firewall profile, phone and PC on different VLANs. Work down this list.

• The Virtual drive screen must be open in the app. The phone only answers while you are on it. The bridge notices you left within about fifteen seconds and goes back to searching.
• Set the PC’s network to Private in Windows network settings, and allow the bridge through the firewall.
• Turn off VPNs on either end.
• Give it the address by hand. After twenty seconds of searching the bridge offers to take one. Read the fallback address off the app’s Connect card and either type it at that prompt or start the bridge with ACBridge.exe --host <phone-address>.

Check the link without the game

Running ACBridge.exe --demo --host <phone-address> streams made-up telemetry, so the cockpit in the app moves even with no game open. If that works, the network is fine and the problem is on the game side.

Worth knowing

• Leave it running all evening. Assetto Corsa starts a fresh session each time you take out a different car; the bridge lets go of the old one and picks up the new one within a second or two.
• It remembers your phone between runs and looks there first, so the second night is quicker than the first.
• The pair code is not a password. It settles which phone, nothing more - anything on your network could already read the telemetry going past.
• Stuck on “waiting” while you are actually driving? That is a bug worth reporting. Run ACBridge.exe --scan and send us what it prints.
