Bug ID: 401983
Summary: With bluetooth integration enabled, system keeps
scanning for new bluetooth devices every now and then.
Product: Bluedevil
Version: 5.14.3
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: daemon
Assignee: now...@gmail.com
Reporter: nekoxmach...@gmail.com
Target Milestone: ---
SUMMARY
BlueDevil seems to be constantly scanning for new bluetooth devices. On my
hardware (and I suspect on any combined wifi/bluetooth chips, which are mostly
found in laptops) this leads to serious deteoriation in wireless connectivity
quality, up to completely loosing a wifi connection for couple minutes after a
day of uptime.
I'd suggest to add a separate configuration tickable to prevent this behaviour.
STEPS TO REPRODUCE
1. Enable BlueDevil "bluetooth integration" feature
2. Open bluetoothctl to monitor for scan("Discovering") requests
OBSERVED RESULT
Software-wise:
Every 2-3 minutes, device goes into "Discovery" mode.
Hardware-wise:
Wireless speed & packetdrop grows, longer it keeps going worse the connectivity
becomes.
EXPECTED RESULT
As this is not a bug per se, while having quite bad outcome AND being a
non-obvious thing to detect/debug, I've set it to Wishlist.
Expected result would be to have a configuration item to disable this behaviour
while keeping other bluetooth integration features; I'd argue that not scanning
continiously should be the default.
SOFTWARE/OS VERSIONS
