show battery percentage of paired devices

[marceloiavenissi]

Hello, in my day-to-day, I use several bluetooth devices with their own battery, but there is no indication of the percentage.
On my Android, I use the BatON application that provides this information; it would be very useful for users to view this information in that extension as well.

Please can you implement this because it would be very useful for me? I am grateful.

I've tried to add this feature, but can't find a way to get battery level of bluetooth device on linux.
I will keep this issue opened. Maybe in future this will be possible.

I think it's not yet possible:

I'm pretty sure UPower can give you this information:

slaw@nyancat:~$ bluetoothctl devices

Not sure how usable or up-to-date this is , but here is another gnome extension that fetches the battery percentage using upower for a specific Bluetooth tablet: https://github.com/fthx/wacom-indicator/blob/main/extension.js#L74 May be that provides some inspirations.

Headset battery is (currently) an experimental feature of bluez. Experimental features can be enabled by passing the -E flag to bluetoothd

1. create a systemd drop-in /etc/systemd/system/bluetooth.service.d/10-experimental.conf with contents

[Service]
ExecStart=
ExecStart=/usr/libexec/bluetooth/bluetoothd -E none

(see #42 (comment))

2. systemctl daemon-reload
3. systemctl restart bluetoothd
