manufacturer data show is for Airpod pro 2nd gen with ligthning cable. But battery level are reported incorrectly. I also read somewhere that mediatek devices have issues with scanning le when experimental features are enabled. So lets disable kernel expermental feature first.

  1. Which linux distro are you using?
  1. Disable kernel experimental flag in /etc/bluetooth/main.conf. Add a # and space in front. Should look this. 
    # Enables kernel experimental features, alternatively a list of UUIDs
# can be given.
# Possible values: true,false,<UUID List>
# Possible UUIDS:
# d4992530-b9ec-469f-ab01-6c481c47da1c (BlueZ Experimental Debug)
# 671b10b5-42c0-4696-9227-eb28d1b049d6 (BlueZ Experimental Simultaneous Central and Peripheral)
# 15c0a148-c273-11ea-b3de-0242ac130004 (BlueZ Experimental LL privacy)
# 330859bc-7506-492d-9370-9a6f0614037f (BlueZ Experimental Bluetooth Quality Report)
# a6695ace-ee7f-4fb9-881a-5fac66c629af (BlueZ Experimental Offload Codecs)
# 6fbaf188-05e0-496a-9885-d6ddfdb4e03e (BlueZ Experimental ISO socket)
# 69518c4c-b69f-4679-8bc1-c021b47b5733 (BlueZ Experimental Poll Errqueue)
# Defaults to false.
# KernelExperimental = true

    Restart laptop

  1. Can copy paste these commands in terminal and post the output here. 
    clear

  1. try the script again. Make sure the airpods are as close as possible to the bluetooth adapter/laptop

I also do not know why this is happening.

For user thapa-sabin who also has mediatek chipset The extension and script works in on Debian But not working in Fedora.

I can only guess what could be the issue, could be one of the following.

  1. Could be an bluez experimental enabled I know that Debian by default comes with Bluez experimental features Disabled. I know that Fedora by default comes with Bluez experimental features Enabled. I also read an very old post that le scan breaks when experimental features are Enabled, but was a very old post and a lot may have changed by then.

Now the problem with Fedora, I did not find a way to Disable Bluez Experimental Feature. I also use Fedora and want to test how to disable it but couldn;t. I posted on the Matrix channel there was not response. On Fedora Forums, you can see the discussion here. https://forums.fedoraforum.org/showthread.php?332958-Disable-Bluez-experimental-feature

Last suggestion was to compile Bluez from source with flag disabled and try it, but I didnt try that.

  1. It could also be a kernel update breaks, enables or disable a feature that doesnt result in BLE scanning, that makes it work in Debian but not in Fedora.

If you really want to go to the trouble of finding out you could boot usb with live ubuntu iso. Like Debian, Ubuntu also shipped with bluez experimental feaure disabled. Although it is a pain to download and create the iso as it is around 6GB download

Run the script

You can even install run the extension wthout install extension.manager app, as it is a pain to install any app or packages on live enviroment but for extension it is easy. Connect to wifi and run the command

busctl --user call org.gnome.Shell.Extensions /org/gnome/Shell/Extensions org.gnome.Shell.Extensions InstallRemoteExtension s Airpod-Battery-Monitor@maniacx.github.com

It will directly install and enable the extension and there is no need to log out / relogin.

Check if the script / extension works. (with experimental feature disable, it is disable by default on ubuntu)

If it works Enable Bluez experimental feature and restart bluetooth service. Do not reboot the system. It will lose everything and you will have to 

sudo  systemctl restart bluetooth

And check again if the script or extension work.

ARdgzC commented 1 month ago

I tried with the latest ubuntu iso on a live usb but I got the same results, I guess i can try with Debian

Update It worked on debian after changin to dual mode

maniacx commented 1 month ago

hmmm. So it doesn't work on ubuntu as well?

Can you do some test.

Run debian

Run these command and post the output here 

bluetoothctl version
bluetoothctl show
btmgmt info
uname -r

Switch to dual mode in /etc/bluetooth/main.conf and check and make sure bluez experimental is disabled by experimental flag=false or commented Make sure the extension works.

Switch experimental flag=true in /etc/bluetooth/main.conf restart bluetooth service. Check if the extension works.

It did not work until I uncommented ControllerMode = dual Screenshot from 2024-07-24 13-05-26

Comparing. btmgmt info for both Fedora and Debian seems like Fedora has some new feature enabled . I wonder if that could be the issue

Supported settings` for Fedora

current settings for Debian

In Fedora we have additional feature supported and enabled cis-central cis-peripheral iso-broadcaster sync-receiver

But I dont know what they do and how to disable just for testing in Fedora. If you know how to disable them try it in Fedora, If I find out I will let you know.

maniacx commented 1 month ago

If you still have Fedora, could you disable Kernel Experimental flag on /etc/bluetooth/main.conf. Remove the #

KernelExperimental = false
sudo systemctl restart bluetooth

And then

btmgmt info

Post the output here and try the extension Also check in bluettoothctl and scan on and see if it post manufacturing data when connected.

This is the output after changing KernelExperimental = false. the extension still not working and there is no manufacturer data in scan on

I was hoping that we could disable this, just for testing but no luck. Seems like on Fedora they have propably compiled bluez with everything enabled, experimental and kernel experimental.
