Initial setup instructions and LED indicators differ depending on your tracker version.
Setup Guide: Dragonfly Set (USB Dongle)
1. Plug in the Receiver & Launch Wizard
Plug the USB dongle into your PC (ideally using a USB extension cable placed directly on your desk for line of sight). Launch SlimeVR Server and open the Setup Wizard.
2. Skip Wi-Fi & Power On Trackers
In the wizard, click Continue with Dongle to skip Wi-Fi credential setup, which is not required for dongle trackers. This brings you straight to the main screen.
Turn on each tracker using the side power switch. They will automatically pair with the dongle and appear green in the app. If any tracker does not show up, run the command Pair in our Web Console and quickly press the side button on the tracker 3 times.
Status LED Indicators (Dragonfly)
| LED | Behavior | Meaning |
|---|---|---|
| Blue | Solid ON | Tracker is charging |
| Blue | OFF (while plugged in) | Battery is fully charged |
| Red | Blinking / Solid ON | Normal operation (searching / sending data) |
| Red | Rapid blinking | Low battery (connect to charger) |
Setup Guide: Wi-Fi Trackers (Step-by-Step)
1. Launch SlimeVR Setup Wizard
Open SlimeVR Server on your computer and launch the Setup Wizard. Make sure your PC is connected to the same local network you intend to use for your trackers.
Important: Trackers support only 2.4 GHz networks (5 GHz Wi-Fi is not supported).
2. Enter Wi-Fi Details & Upload via Cable
Select the Wi-Fi option in the wizard and enter your network name (SSID) and password.
Connect a tracker to your PC using a USB-C cable and turn it on. The application will detect the serial port and flash the credentials into tracker memory within seconds. Disconnect the cable and repeat for all remaining trackers.
3. Connect Trackers to Network
Once credentials are saved on all trackers, click I connected all my trackers. The trackers will log into your Wi-Fi network, and their status icons on the dashboard will turn green.
Status LED Indicators (Wi-Fi Version)
| LED | Behavior | Meaning |
|---|---|---|
| Blue | Blinking | Active operation (searching Wi-Fi / transmitting data) |
| Red | Solid ON | Charging in progress |
| Green | Solid ON | Battery is fully charged |
Step 2: Assignment & In-Game Calibration
Tracker Assignment
Navigate to Tracker Assignment in the application[cite: 1]. If you are not sure which physical tracker corresponds to which body part, shake it — the corresponding entry in SlimeVR will highlight immediately[cite: 1]. Click on the designated body part (e.g., Waist, Right Thigh, Left Ankle) to assign it[cite: 1].
Recommendation for VRChat: Under Settings > Gesture control, disable Tap based resets[cite: 1]. This prevents accidental recalibration during fast dancing or jumping[cite: 1].
Fastening Straps & Mounting Calibration
Fasten the straps snugly so the trackers do not shift or rotate during movement[cite: 1]. Put on your VR headset, stand straight with legs together (I-Pose), and run Mounting Calibration in SlimeVR[cite: 1].
Body Proportions Configuration
For tracking to feel natural and accurate in-game, SlimeVR needs your limb lengths. Click on Body Proportions in the side menu[cite: 1].
The simplest method is Automatic Calibration. Stand up straight, begin the process, and follow the on-screen prompts (you will be asked to perform small movements like squats and side-steps).
Once finished, launch VRChat, adjust your avatar height to match your real eye level, and complete final avatar calibration in T-Pose[cite: 1].
Playing Natively on Meta Quest 2 & 3 (Standalone)
1. Native SlimeVR on Quest (Recommended)
You can sideload the SlimeVR Server application (.apk file) directly into your Quest using SideQuest. The server runs completely in the background on the headset.
• Wi-Fi Trackers: Communicate with the Quest over your local Wi-Fi router.
• Dragonfly Dongle: Plug the USB receiver directly into the Quest's side USB-C port using an OTG adapter.
2. Non-Gaming Laptop (as OSC Host)
Have a basic office laptop? It does not need to handle VR games — it only acts as an external calculation engine running SlimeVR Server.
The laptop collects tracker data (via Wi-Fi or the plugged-in USB dongle) and streams calculated skeletal coordinates directly to your Quest headset over Wi-Fi via OSC.
3. Android Phone (as OSC Host)
Since the Meta Quest operating system is based on Android, the official mobile SlimeVR Server build runs on modern Android smartphones as well.
The phone processes motion data and sends it to the Quest via OSC. It supports both Wi-Fi trackers and the Dragonfly Dongle (plugged into the phone’s USB-C port via a standard OTG adapter).
