Bug ID: 434853
Summary: Battery indicator for Bluetooth headset only shows up
occasionally
Product: Powerdevil
Version: 5.21.3
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: patrick.auer...@gmail.com
Target Milestone: ---
SUMMARY
The battery indicator in the Plasma system tray shows the charge status for my
Bluetooth headset (Sennheiser HD 450BT) only for a few seconds after turning on
the Bluetooth receiver,
but vanishes quickly after that.
It's also quite inconsistent to reproduce, and I'm still not quite sure under
which conditions it exactly shows up.
STEPS TO REPRODUCE
1. Toggle power of Bluetooth receiver
2. Open power indicator widget in system tray
OBSERVED RESULT
The battery status is shown for a few seconds.
Sometimes it's showing the correct approximate charge, sometimes it's just
shown as 0%.
EXPECTED RESULT
The battery status is shown in the Bluetooth widget like it is for other
devices.
SOFTWARE/OS VERSIONS
Linux: 5.11.7
KDE Plasma Version: 5.21.3
KDE Frameworks Version: 5.80.0
Qt Version: 5.15.2
ADDITIONAL INFORMATION
I was able to connect the device and get the battery info consistently with
this python script
https://github.com/TheWeirdDev/Bluetooth_Headset_Battery_Level
The battery status does also show up correctly when I connect it to my Android
phone.
