App works on non-rooted OP13 running OxygenOS 16, but airpods randomly disconnect + case battery shows 0%

[FilBr]

First of all, I'm fully aware that I'm running the app outside of it's intended scope, but.
I've been watching this repo for some time hoping for the bluetooth bug to be solved, and to my surprise I can now use the LibrePods app on a non-rooted device running OxygenOS 16!

Not everything is working,

• Case battery shows 0% most of the time
• Airpods sometimes randomly disconnect when the case is opened
• Head tracking doesn't work
• Missing hearing aid settings for APP2
• Missing transparency customization settings for APP2

but the fact that the app manages to get some data from my airpods on a non rooted devices is a huge win.

I know this is might be out of scope, but I'd love to try and help improving the support for non-rooted devices

Lovely to see some company noticing this small personal project, Google has decided to neglect it despite 1500+ upvotes.

The case battery is zero when you don't have any airpods in the case. iOS uses find my to get the battery of the case in such cases, but I haven't reverse engineered that yet.

About the random disconnection- do you see any options in the native settings app for airpods? I think if they implemented a fix in the stack, they probably have implemented at least some parts of the app in their skins.

[kavishdevar]

And this is not at all outside the intended scope! This is what I was hoping would happen when Google fixes it. And some stuff like setting the battery of a BluetoothDevice to show in Settings, the hook for hearing aid etc., to be limited to root.

I heard oppo/oneplus were adding support for AirPods a few weeks back, and I was waiting for a system image to be released so that I could see if they fixed this.

@kavishdevar thanks for the quick response!

I was hoping for this, but I either haven't found it yet, or it's not there. Here are is how I currently see my airpods in system settings

Compared to settings available for OnePlus earbuds

I heard oppo/oneplus were adding support for AirPods a few weeks back, and I was waiting for a system image to be released so that I could see if they fixed this.

Let me know if there's anything I can do to help on this front

[kavishdevar]

Interesting, so they just let you run my app- amazing! That means I can add new features any time, without oppo having to update :)

Let me know if there's anything I can do to help on this front

Nope, thank you! I just wanted to see if there's anything that they fixed or just rumors. Now I can add this to the README.

It would be great if you could test the hearing aid/transparency customization feature too. I am curious to know if they removed the need for the additional hook as well. Try customizing the amplification, tone etc., from Accessibility settings and see if it actually affects the AirPods.

[kavishdevar]

But this also means there is something else causing the disconnection. Could you tell me exactly steps to reproduce that?

[FilBr]

It would be great if you could test the hearing aid/transparency customization feature too.

It doesn't look like I have hearing aid/transparency customization related setting.
I tried adjusting the "Tone volume" slider here but it doesn't affect the audio.

[FilBr]

and this is what I see when I go into the settings in the top right

[FilBr]

As for the random disconnections, I will need to test more. Will come back to you after I have the time to test properly

[FilBr]

On a sidenote, I'm currently running the 0.1.0-rc.4 version.
I tried installing the v0.2.0-alpha, but it crashes as soon as I open the app. Even after trying to do a fresh install, I can get through the "Grant permissions" page, but as soon as I give all the permissions, the app crashes.

[FilBr]

I have also tried using the head tracking, but it doesn't detect any movement

[kavishdevar]

Sorry, my bad. Both of those were added in v0.2.

I added something that needs root. I was under a very wrong assumption that this app will never see the daylight of non-rooted phones lol. Will fix the problems, but could you grab the logs (preferably with logcat -b crash, just so that if I'm chasing the right issue.)

Try enabling alternate head tracking packets in the app's settings. (yeah this should be done by the app itself, it will someday)

these are the logs from the crash event

Try enabling alternate head tracking packets in the app's settings. (yeah this should be done by the app itself, it will someday)

I'm not quite sure where to find this setting? I tried going through the system settings, then navigating to the app settings but couldn't find anything there

Does it not change the volume of the tones played, like when changing the listening mode, etc.?

Can confirm there's no change in the audio when moving the slider

[kavishdevar]

@FilBr Here's the action run: https://github.com/kavishdevar/librepods/actions/runs/19412004970 for the apk. (#253)

I have fixed the crash. This has the hearing aid features and transparency features as well which I am not sure if it will work. I have bypassed the check for act as apple device hook for you to test

Can confirm there's no change in the audio when moving the slider

Weird, it seems to work for me (there isn't anything else for tone volume in the macos/ios bluetooth stack either). Do you know what firmware version your AirPods are on?

Sorry, it was possibly added after the v0.1.0-rc.4 release. It's been a few months since I released a new version :/
