# ALN - AirPods like Normal (Linux Only)

### Check out the packet definitions at [AAP Definitions](/AAP%20Definitions.md)

## Currently supported device(s)
- AirPods Pro 2

### 1. Install the required packages

```bash
sudo apt install python3 python3-pip
pip3 install pybluez
```

If you want to run it as a daemon (Refer to the [Daemon Version](#as-a-daemon-using-a-unix-socket) section), you will need to install the `python-daemon` package.

```bash
pip3 install python-daemon
```

### 2. Clone the repository

```bash
git clone https://github.com/kavishdevar/aln.git
cd aln
```

### 3. Preprare
Pair your AirPods with your machine before running this script!
> **Note:** DO NOT FORGET TO EDIT THE `AIRPODS_MAC` VARIABLE IN EXAMPLE SCRIPTS  WITH YOUR AIRPODS MAC ADDRESS BEFORE RUNNING THEM!

# Versions

## Non-Daemon based
This version is the most polished version of the script. It can do the following:
- fetch the battery percentage,
- fetch in-ear status (but not actually controlling the media with that information).
- control ANC modes
```bash
python3 examples/logger-and-anc.py
```

## As a daemon (using a UNIX socket)
![Daemon Log Screenshot](imgs/daemon-log.png)
If you want to run a deamon for multiple programs to read/write airpods data, you can use the `airpods_daemon.py` script.
- This creates a standard UNIX socket at `/tmp/airpods_daemon.sock` and listens for commands
- and sends battery/in-ear info
You can run it as follows:

```bash
python3 airpods_daemon.py
```

## Interacting with the daemon
![Set ANC Screenshot](imgs/set-anc.png)
- Sending data to the daemon
You can send data to the daemon using the `set-anc.py` script. Since it's a standard UNIX socket, you can send data to it using any programming language that supports UNIX sockets.

This package includes a demo script that sends a command to turn off the ANC. You can run it as follows:

```bash
python3 examples/daemon/set-anc.py
```

- Reading data from the daemon
![Read Data Screenshot](imgs/read-data.png)
You can listen to the daemon's output by running the `read-data.py` script. This script listens to the UNIX socket and prints the data it receives. Currenty, it recognizes the battery percentage and the in-ear status and dumps the rest of the data to the terminal.

```bash
python3 examples/daemon/read-data.py
```

- Controlling the media with the in-ear status (and get battery status)

![Ear Detection Screenshot](imgs/ear-detection.png)
This script is basically the standalone script, but interacts with the UNIX socket created by the daemon instead. It can control the media with the in-ear status and remove the device as an audio sink when the AirPods are not in your ears.

```bash
python3 examples/daemon/ear-detection.py
```

- App Indicator/Tray Icon

![Tray Icon Hover Screenshot](imgs/tray-icon-hover.png)
![Tray Icon Menu Screenshot](imgs/tray-icon-menu.png)
This script is a simple tray icon that shows the battery percentage and set ANC modes. It can also control the media with the in-ear status.
> Note: This script uses QT.

```bash
python3 examples/daemon/tray.py
```

## Standalone version (without module dependency, mainly for testing, and reverse engineering purposes)
- Controlling the media with the in-ear status.
- Remove the device as an audio sink when the AirPods are not in your ears. 
- Try to connect with the AirPods if media is playing and the AirPods are not connected.
- Control ANC modes.
  
```bash
python3 examples/standalone.py
```
