 # What is LibrePods?
 
-LibrePods unlocks Apple's exclusive AirPods features on non-Apple devices. Get access to noise control modes, adaptive transparency, ear detection, hearing aid, customized transparency mode, battery status, and more - all the premium features you paid for but Apple locked to their ecosystem.
+LibrePods allows you to use AirPods features that are exclusive to Apple devices. It implements the proprietary protocol used to exchange data between AirPods and Apple devices, enabling features like changing noise control modes, fast ear detection, accurate battery status, head gestures, conversational awareness, and more on non-Apple platforms.

-- **Multi-device connectivity\*** (upto 2 devices)
-- **Other customizations**:
-  - Rename your AirPods
-  - Customize long-press actions
-  - All accessibility settings
-  - And more!
+The following features related to Find My are planned, but require further RE and might need root on Android:
 
-&ast; Features marked with an asterisk require the VendorID to be change to that of Apple.
+- Add your AirPods to the Find My network
+- Play sound through charging case to find it
+- Notify when leaving behind
+- Toggle case charging sounds
 
-# Platform Support
+## Spatial Audio
 
-## Linux
-for the old version see the [Linux README](./linux/README.md). (doesn't have many features, maintainer didn't have time to work on it)
+The app does not currently provide head tracking information to Android for the OS to perform HRTF. This has not been explored completely, and it might need root. 
 
-new version in development ([#241](https://github.com/kavishdevar/librepods/pull/241))
+Spatializing stereo sound is beyond this project's scope and will never be available. Many OEMs have an implementation of their own for this.
 
-![new version](https://github.com/user-attachments/assets/86b3c871-89a8-4e49-861a-5119de1e1d28)
+## Heart Rate Monitoring (AirPods Pro 3 and later)
+This is being worked upon, check the #⁠reverse-engineering channel on the LibrePods Discord server for more information. If it is ever implemented, it will most likely need root on Android.
 
-## Android
+## High quality two-way audio
+On iOS/iPadOS, you can continue using A2DP while AirPods send the audio stream from its microphone over AACP. 
 
-### Screenshots
+Since this needs deeper integration with audio on Android, it will most likely need root.

-### Root Requirement
-
-LibrePods **may** require root depending on your device/OS and what features you want access to:
-
-- Features requiring the VendorID hook ([the features marked with an asterisk here](https://github.com/kavishdevar/librepods#key-features)) will always require root regardless of your device/OS.
-- On **ColorOS/OxygenOS 16** and **Pixel devices on Android 16 QPR3** (with the latest Google Play system update), LibrePods does not need root for most features (except those requiring the VendorID hook mentioned above).
-- On other devices, LibrePods needs root because of a bug in the Android Bluetooth stack Fluoride/non-compliance of Apple with Bluetooth standards. You must have Xposed installed for the app to workaround this bug and connect to AirPods. [This issue is being tracked here](https://issuetracker.google.com/issues/371713238). Please do not comment on the issue thread. The issue has already been resolved and should be available in **Android 17** for all devices.
-
-> [!IMPORTANT]
-> This workaround with Xposed is not guaranteed to work on all devices.
-
-### Troubleshooting steps for common errors
-- Ensure the correct scope is set in LSPosed/Vector.
-- Ensure there is no root-hiding module preventing the hook from loading on the Bluetooth app.
-- Restart your phone after confirming the scope.
-
-### A few notes
-
-- Due to recent AirPods' firmware upgrades, you must enable `Off listening mode` to switch to `Off`. This is because in this mode, loud sounds are not reduced.
-
-- If you have take both AirPods out, the app will automatically switch to the phone speaker. But, Android might keep on trying to connect to the AirPods because the phone is still connected to them, just the A2DP profile is not connected. The app tries to disconnect the A2DP profile as soon as it detects that Android has connected again if they're not in the ear.
-
-- When renaming your AirPods through the app, you'll need to re-pair them with your phone for the name change to take effect. This is a limitation of how Bluetooth device naming works on Android.
-
-- If you want the AirPods icon and battery status to show in Android Settings app, install the app as a system app by using the root module.

-# Changing VendorID in the DID profile to that of Apple
+# VendorID Spoofing
 
 Turns out, if you change the VendorID in DID Profile to that of Apple, you get access to several special features!
 
-You can do this on Linux by editing the DeviceID in `/etc/bluetooth/main.conf`. Add this line to the config file `DeviceID = bluetooth:004C:0000:0000`. For android you can enable the `act as Apple device` setting in the app's settings.

 All hearing aid customizations can be done from Android (linux soon), including setting the audiogram result. The app doesn't provide a way to take a hearing test because it requires much more precision. It is much better to use an already available audiogram result. 
 
+# Protocol and Reverse Engineering
+
+Please refer to the Wireshark dissector plugin by Nojus ([@pabloaul](https://github.com/pabloaul)) for more information on the protocols used: [pabloaul/apple-wireshark](https://github.com/pabloaul/apple-wireshark)
+
+The dissector had not been used in LibrePods for most of the implementation; I had reverse engineered the protocol myself before this dissector was made. But many (future) features including two-way high quality audio and spatial audio would not have been possible without their RE efforts!
+
+# Use of AI
+
+## Android app
+
+These parts of the app were completely AI-generated: 
+- Head Gestures - all of it, including logic and the UI
+- The offset setup with r2+the xposed module (both versions)
+- Troubleshooter and LogCollector
+
+Rest everything- the background service, the Bluetooth manager classes (AACP and ATT), the entire UI, even the smallest components were written manually.
+
+Some parts of the UI components were borrowed from [Kyant0's demo app](https://github.com/Kyant0/AndroidLiquidGlass/tree/master/catalog), which is licensed under [Apache License 2.0](https://www.apache.org/licenses/LICENSE-2.0).
+
+## Linux (rewrite)
+
+The `aacp.rs` and the `att.rs` files were translated from Kotlin to Rust with AI. Some parts of the `media_controller.rs` file, mainly the pulse integration, was also AI-generated.

+> This workaround with Xposed is not guaranteed to work on all devices.
+

+
+### GitHub Releases
+
+If you need xposed because of the [root requirement](#root-requirement), you will have to use the apk/zip from the [GitHub releases](https://github.com/kavishdevar/librepods/releases/latest).
+
+### As a system app (root module)
+
+If you want LibrePods to have privileged Bluetooth permissions to 
+- show battery status in the system settings and widgets
+- show AirPods icon in the system settings (xposed is also currently required for this)
+- switch audio to phone speakers when you are not wearing your AirPods
+
+you can install the root module. This is optional and only provides extra features, but it is not required for the app to work.
+
+> [!IMPORTANT]
+> When using the root module, do not install the Play Store version. There might be issues because of the signature mismatch between the Play Store version and the root module.
+
+## Nightly/Development Builds
+
+Want to try the latest features before they're officially released? You can grab nightly builds from the [latest nightly release](https://github.com/kavishdevar/librepods/releases?q=nightly).
+
+> [!WARNING]
+> These builds are automatically generated from the latest code and may contain new features and bug fixes that haven't been included in a stable release yet. However, please note that they may also be less stable than official releases, so use them at your own risk.

+# LibrePods on Linux
+
+A new rewrite is being worked upon. Please look at the list of features in the root README to see what's supported in the new version. 
+
+The rewrite can be found in the `linux/rust` branch [here](https://github.com/kavishdevar/librepods/tree/linux/rust/linux-rust). Follow the development in [PR #241](https://github.com/kavishdevar/librepods/pull/241). 
+
+
+## Installation
+
+### GitHub Releases
+
+The app is ready to download as an AppImage or an executable. You can download the latest pre-release from the [GitHub releases](https://github.com/kavishdevar/librepods/releases?q="linux-v0").
+
+### Nightly Builds (recommended)
+
+You can also try the latest build of the new version from the [GitHub Actions artifacts](https://github.com/kavishdevar/librepods/actions/workflows/ci-linux-rust.yml). On the latest successful workflow run, download the **librepods-x86_64.AppImage** or **librepods** binary from **Artifacts**.

 ### Why a separate script?
 
 Because I discovered that QBluetooth doesn't support connecting to a socket with its PSM, only a UUID can be used. I could add a dependency on BlueZ, but then having two bluetooth interfaces seems unnecessary. So, I decided to use a separate script for hearing aid features. In the future, QBluetooth will be replaced with BlueZ native calls, and then everything will be in one application.
