# PPT Remote

Control PowerPoint from your Android phone over Wi-Fi.

## Server (Windows PC)

Requirements: [Bun](https://bun.sh) installed, PowerPoint open with a presentation.

```bash
cd server
bun install
bun start
```

The server listens on port **8765**. Find your PC's local IP with `ipconfig`.

## Server (Linux)

Requirements: Bun, LibreOffice, python3 (with `uno` module — ships with LibreOffice), xdotool.

```bash
sudo apt install xdotool  # or equivalent for your distro
```

Start LibreOffice Impress with the UNO socket listener enabled:

```bash
libreoffice --impress --accept="socket,host=localhost,port=2002;urp;StarOffice.ServiceManager" your-presentation.pptx
```

Then start the server:

```bash
cd server
bun install
bun start
```

Find your machine's local IP with `ip addr` or `hostname -I`.

## Client (Android)

Requirements: Flutter SDK.

```bash
cd client
flutter pub get
flutter run
```

Enter your PC's local IP and port `8765`, then tap Connect.

## How it works

- Server auto-detects the platform (`process.platform`) and picks the right driver.
- Windows: PowerShell COM automation via `GetActiveObject('PowerPoint.Application')`.
- Linux: navigation via `xdotool` key events, slide state and image export via Python UNO connected to LibreOffice's socket listener on port 2002.
- After each navigation, the current slide is exported as an image and sent as base64 to all connected clients.

## Notes

- PowerPoint must already be open on the PC before connecting.
- The slideshow must be running (or use "Start Show") for next/prev to work.
- Both devices must be on the same Wi-Fi network.
- Windows Firewall may need to allow port 8765.
