How to Set Up SlimeVR Trackers for VRChat: Software, Wi-Fi, Charging and Placement

Quick answer: to set up SlimeVR trackers for VRChat, install the current SlimeVR Server and SteamVR software, connect each tracker to a 2.4GHz Wi-Fi network with the included USB data cable, charge the trackers until the indicator turns green, wear them in stable positions, and calibrate before entering a world. For a six-tracker setup, use one tracker on the chest, one on the hip, two on the upper legs, and two on the lower legs.

A good full body tracking session starts before you put on the headset. Most first-session problems come from four places: incomplete software setup, the wrong Wi-Fi band, a charge-only cable being used for configuration, or a tracker that moved after calibration. The process below puts those checks in a practical order so you can solve problems outside VR instead of troubleshooting in a crowded VRChat world.

This guide is written for the FBTKit SlimeVR-compatible tracker workflow on Windows 10 or 11. SlimeVR changes over time, so use the current installer and the official documentation as the source of truth whenever an older printed guide and the current software disagree.

What You Need Before Starting

If your kit has just arrived, you can also use the after-delivery setup checklist to inventory the trackers, straps, case, adapter, and cables before continuing.

Step 1: Install SlimeVR, SteamVR, and VRChat

Start with the current SlimeVR installer. The current installer is safer than following an old list of separate dependencies because bundled components and requirements can change. Do not install a separate Java version only because an older instruction sheet mentions it; follow the current installer or current SlimeVR documentation if it asks for an additional component.

1. Install SlimeVR Server. Download the current Windows installer, complete the installation, and open the server once.
2. Install Steam and SteamVR. Sign in to Steam, search for SteamVR, and install it.
3. Install VRChat if needed. You can skip this during hardware-only testing, but it is required for the final VRChat check.
4. Connect your headset. Start SteamVR and complete Room Setup if SteamVR requests it.
5. Confirm basic VR tracking. Make sure the headset and controllers appear and move correctly before adding body trackers.

A reliable launch order is SteamVR → SlimeVR Server → VRChat. Opening the software in the same order every time makes it easier to identify which connection failed.

Step 2: Connect Every Tracker to 2.4GHz Wi-Fi

SlimeVR-compatible Wi-Fi trackers use the 2.4GHz band. A router may display one network name for both 2.4GHz and 5GHz, but the 2.4GHz band still needs to be enabled. If band steering causes setup trouble, temporarily use a clearly named 2.4GHz network or a 2.4GHz hotspot.

Configure one tracker at a time:

1. Connect one tracker to the computer with the included white USB data cable.
2. Open SlimeVR Server and power on that tracker.
3. Follow the Wi-Fi setup prompt and enter your 2.4GHz SSID and password.
4. Wait until the tracker is detected over Wi-Fi.
5. Disconnect it, then repeat the same process for the next tracker.

The supplied quick-start information lists MIOBERRY with password 123456 as a factory fallback hotspot profile. Use this only when your trackers still have that factory profile and you intentionally create a matching 2.4GHz hotspot. After a tracker has been configured with your own network details, use the network you saved in SlimeVR Server.

If a tracker does not appear after Wi-Fi setup

• Confirm that the network is 2.4GHz, not 5GHz-only.
• Use letters and numbers in the SSID when possible; avoid unusual symbols while testing.
• Make sure the tracker and computer are on the same local network and that client isolation is disabled.
• Avoid a WPA3-only test network if the tracker cannot join it.
• Check whether the router limits the number of connected devices.
• Try the white data cable again. A charging-only cable can supply power without creating the data connection needed for configuration.

Step 3: Charge the Trackers Before Calibration

Charge the trackers before diagnosing a software or network problem. Low battery can make Wi-Fi unstable, stop battery reporting, or cause repeated disconnects that look like a configuration error.

• Charge when SlimeVR Server shows about 5% or less.
• A red indicator means the tracker is charging.
• A green indicator means charging is complete.
• Allow at least two hours when you need a full charge.
• Power trackers off before charging when practical.
• If the trackers will not be used for a long period, store them above 50% charge rather than completely empty.

Battery life varies with the tracker configuration, Wi-Fi signal, battery condition, and session. This guide therefore uses the indicator lights and reported charge level instead of promising an exact number of hours. For a repeatable pre-session habit, see the full body tracking charging routine.

Step 4: Wear a Six-Tracker Setup in Stable Positions

For a balanced six-tracker configuration, place one tracker on the chest, one on the hip, one on each upper leg, and one on each lower leg. The goal is not only to choose the correct body part. Each tracker must also stay in the same orientation while you move.

Keep the USB-C charging port pointing down and the front face pointing forward when that matches the body assignment in SlimeVR Server. Tighten each strap enough to prevent sliding, but not so tightly that it becomes uncomfortable. Lower-leg trackers usually work better near a stable shin or ankle position than on a loose part of the calf.

Body proportions and clothing change how a strap feels. If you move any tracker after calibration, recalibrate. For more fit detail, read the tracker strap placement guide and compare the result with the official SlimeVR page on putting on trackers.

Step 5: Assign Trackers and Run the First Calibration

With the trackers connected and worn, open SlimeVR Server and confirm that every device is online. Assign each tracker to the matching body position, check its orientation, and follow the current setup flow in the server.

1. Stand in a neutral position with your feet straight and your body facing forward.
2. Check that the tracker names and body assignments match the physical locations.
3. Run the required reset or calibration step shown by the current SlimeVR Server.
4. Turn slowly, take a small step, lift each foot, and sit only if your play space is safe.
5. If one body part rotates incorrectly, fix that tracker assignment or orientation before recalibrating.

The official SlimeVR initial setup documentation should be your reference for the current server screens. If the avatar still looks wrong after the first pass, use the beginner calibration routine instead of changing several settings at once.

Final VRChat Pre-Join Checklist

• SteamVR detects the headset and controllers.
• SlimeVR Server shows every tracker online.
• All trackers are on the intended 2.4GHz network.
• Battery levels are sufficient for the planned session.
• Tracker assignments match chest, hip, left/right upper legs, and left/right lower legs.
• Ports and front faces are oriented consistently.
• Straps stay in place when you turn, step, sit, and stand.
• The avatar looks correct in a quiet test world before you join friends.
