Flatpak Installation (Recommended for Steam Deck/Bazzite)

1. Install Flatpak and Flatpak Builder (if not already installed):

   sudo dnf install flatpak flatpak-builder

2. Build the Flatpak package:

   flatpak-builder --user --install build-dir io.github.Mozinho85.DeckSend.json

3. Launch DeckSend from your application menu!

4. (Optional) Export a bundle for easy sharing:

   flatpak build-bundle build-dir DeckSend.flatpak io.github.Mozinho85.DeckSend

   You can then double-click DeckSend.flatpak to install on any Flatpak-enabled system.

---

Graphical Installer (Recommended for Bazzite/Fedora Immutable)

1. Copy the project folder to your Steam Deck.
2. In Desktop Mode, right-click install_decksend.sh, go to Properties → Permissions, and check "Is executable".
3. Double-click install_decksend.sh to run the installer.
4. Follow the prompts. The app will build and install itself, and a launcher will appear in your app menu.

The installer will automatically use toolbox (if available), rpm-ostree, or dnf as needed.

---

Manual Installation (Advanced)

If you prefer, you can still build and install manually using toolbox, rpm-ostree, or dnf as described earlier in this README.

Example: Main Entry Point (main.c)

Below is the main entry point for the sender app. It initializes input and Bluetooth, reads controller events, builds HID reports, and sends them over Bluetooth:

#include "input.h"
#include "bluetooth.h"
#include "hid.h"
#include <stdio.h>

int main() {
   printf("Steam Deck Sender App Starting...\n");
   if (init_input() != 0) {
      fprintf(stderr, "Failed to initialize input\n");
      return 1;
   }
   if (init_bluetooth() != 0) {
      fprintf(stderr, "Failed to initialize Bluetooth\n");
      return 1;
   }
   while (1) {
      struct ControllerEvent event;
      if (read_input_event(&event) == 0) {
         unsigned char report[64];
         build_hid_report(&event, report);
         send_hid_report(report, sizeof(report));
      }
   }
   cleanup_input();
   cleanup_bluetooth();
   return 0;
}

Steam Deck Sender App

This app lets you use your Steam Deck as a Steam Controller on a Linux PC (Fedora/Bazzite).

Features

• Captures button and trackpad events
• Emulates Steam Controller over Bluetooth HID (work in progress)
• Sends controller input to paired PC for native Steam support

Requirements

• Bazzite (Fedora) on Steam Deck
• Bluetooth enabled
• Dependencies:
  • cmake
  • gcc
  • libevdev-devel
  • bluez
  • bluez-libs-devel

Installation on Steam Deck (Bazzite/Silverblue/Fedora Immutable)

Option 1: System-wide install with rpm-ostree

1. Open a terminal in Desktop Mode.
2. Run:

   sudo rpm-ostree install git cmake gcc libevdev-devel bluez bluez-libs-devel

3. Reboot your Steam Deck after installation.

Option 2: Use a Toolbox (Recommended for Development)

1. Create and enter a toolbox:

   toolbox create
   toolbox enter

2. Install dependencies inside the toolbox:

   sudo dnf install -y git cmake gcc libevdev-devel bluez bluez-libs-devel

Clone and Build

git clone https://github.com/Mozinho85/DeckSend.git
cd DeckSend/steamdeck_sender
mkdir build
cd build
cmake ..
make

---

Run the App

sudo ./steamdeck_sender

• You may need to adjust input device paths in the code if you get errors about input devices.

---

Bluetooth Setup

Make sure Bluetooth is enabled:

sudo systemctl start bluetooth

Pair your Steam Deck with your PC using Bluetooth settings.

---

Notes

• For immutable systems, toolbox is recommended for development.
• If you encounter issues, ensure you are in Desktop Mode and have a working network connection.

Bluetooth Setup

• Make sure Bluetooth is enabled:

  systemctl start bluetooth

• Pair the Steam Deck with your Fedora PC using Bluetooth settings.

Notes

• Bluetooth HID emulation is a work in progress. Steam Controller detection may require further protocol implementation.
• For advanced configuration, edit the source files as needed.
