# VR Hotspot

VR Hotspot turns your Linux PC into a dedicated Wi-Fi access point for your VR
headset using a USB Wi-Fi adapter. You get a direct, low-latency PC ↔ headset
connection optimized for VR streaming, remote access, and headset development —
no router required.

It's ideal if you travel with a MiniPC or "headless" computer puck and want to
connect a VR headset and stream to it, even without a monitor.

> **Release candidate:** VR Hotspot is currently at **v1.1.0-rc4 — Developer
> Hub**. This is the final public validation release before stable v1.1.0.
> Please report anything that does not work as expected.

## Developer Hub

This is the release where VRhotspot stops being just a dedicated hotspot and
becomes a complete Linux VR development workflow.

For the normal Quest setup, connect the headset by USB, approve debugging, and
select **Set up wireless headset**. Developer Hub automatically moves the Quest
to the dedicated VRhotspot network, verifies its SSID, address, gateway, and
route, enables wireless ADB, and lets you remove the USB cable. No typing IP
addresses, pairing codes, passwords, or ADB commands during the normal flow.

If Horizon OS blocks automatic enrollment, Developer Hub falls back to clear
in-headset instructions and privacy-aware credential assistance while keeping
the same strict network verification.

## Install

Run these two commands in a terminal:

```bash
curl -sSL https://raw.githubusercontent.com/josethevrtech/VRhotspot/main/install.sh -o /tmp/vrhotspot-install.sh
sudo bash /tmp/vrhotspot-install.sh
```

The installer:

- Auto-detects your OS (SteamOS, Bazzite, CachyOS, Arch, EndeavourOS, Ubuntu, Fedora)
- Installs required dependencies automatically where the platform permits it
- Configures NetworkManager to prevent interference
- Starts the service and shows you the web UI URL and API token
- Is beginner-friendly — no Linux knowledge required

For guided prompts, add `--interactive`. For automation or managed installs,
see [Advanced installation](docs/advanced-install.md).

### SteamOS note

On SteamOS, always **download the installer first and run it as a local file**
(exactly as shown above). Do not pipe the script straight into bash
(`curl | bash`) on SteamOS.

---

## Open the Web UI

Once installed, open the web UI in a browser:

- **On the same PC:** `http://127.0.0.1:8732`
- **From another device:** `http://<your-pc-ip>:8732`

Then:

1. Enter your **API token** (shown at the end of installation — see
   [Retrieve your API token](#retrieve-your-api-token) if you lost it)
2. Select your Wi-Fi adapter (wlan1 recommended over wlan0)
3. Click **Start** to create your hotspot
4. Connect your VR headset to the new network, or use Developer Hub to enroll a
   Quest automatically for wireless development

## Flatpak desktop companion (optional)

The installer can also set up an optional desktop tray app (Flatpak) for
starting, stopping, and monitoring the hotspot without opening a browser. The
guided installer asks whether to install it (default: No), and pairs it with
the daemon automatically when you say Yes.

See [Flatpak desktop companion](docs/flatpak-companion.md) for requirements,
pairing details, tray behavior, and how authentication is stored.

---

## Retrieve your API token

The installer generates a secure API token and shows it when installation
finishes. To see it again later:

```bash
sudo cat /etc/vr-hotspot/env
```

Look for the line:

```bash
VR_HOTSPOTD_API_TOKEN=<your-token>
```

Treat this token like a password — anyone with it can control your hotspot.

---

## Uninstall

```bash
sudo bash /var/lib/vr-hotspot/app/uninstall.sh
```

This runs the uninstaller that was installed with VRhotspot (the same command
shown on the installer completion screen). It removes the daemon and, if
present, the optional Flatpak companion and its app data. Shared Flatpak
runtimes and unrelated apps are never touched.
Details: [Flatpak desktop companion](docs/flatpak-companion.md).

**Fallback:** if `/var/lib/vr-hotspot/app/uninstall.sh` is missing or your
install is broken, download and run the uninstaller directly:

```bash
curl -sSL https://raw.githubusercontent.com/josethevrtech/VRhotspot/main/uninstall.sh -o /tmp/vrhotspot-uninstall.sh
sudo bash /tmp/vrhotspot-uninstall.sh
```

## Supported distros

- **SteamOS** (validated on 3.8.12 stable — see the
  [SteamOS note](#steamos-note) above)
- **Bazzite** — Bazzite is a supported target through the dedicated
  `rpm-ostree` installer path. VR Hotspot uses its
  bundled hostapd/dnsmasq stack on Bazzite instead of layering system copies.
  If another required base tool is missing, the installer first attempts live
  package layering; when that is unavailable, it stages the packages and asks
  you to reboot and rerun the installer.
  The installer never reboots your system automatically.
- **CachyOS, Arch, EndeavourOS**
- **Ubuntu**
- **Fedora**

More detail: [Platform compatibility guide](docs/PLATFORM_COMPATIBILITY.md).

You'll also need a Wi-Fi adapter that supports AP mode — see
[Supported Wi-Fi adapters](docs/wifi-adapters.md) for tested recommendations.
