[SOLVED] Notebook wakes up from sleep because of bluetooth headset

lundibundi · 2018-06-07 18:26:32

The problem is that my notebook wakes up almost immediately if my Bluetooth headset is connected and will continue to do so until I disconnect the headset.
I usually suspend via KDE shortcut for sleep, but even by manually issuing

systemctl suspend

the result is the same.
My headset Sony MDR-XB950bt has bluetooth v3.0,
Notebook has Bluetooth 4.2 via 'Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)'
Also I have used this to fix my headset's A2dp issues Bluetooth Pairing on Dual boot of Windows & Linux Mint/Ubuntu - Stop having to Pair Devices because every time I used windows/linux I needed to remove/add headset as a new device.

My network controller is here on pci

03:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)

And it's seems disabled here:

cat /proc/acpi/wakeup

Device  S-state   Status   Sysfs node
PEG0      S4    *disabled  pci:0000:00:01.0

XDCI      S4    *disabled

Thanks for your help in advance. I'll be happy to provide any information needed.

Cross-check lsusb to ensure BT isn't wired via USB - you usually get an extra entry for wifi and BT.
In case, you could try to unbind the device. Also rfkilling BT in a sleep hook in /usr/lib/systemd/system-sleep/ might work.

Well, I'm not sure if it is, I have this 24f0:0142 and this 8087:0a2b Intel Corp. which may be the one but I'm not sure how to check. Can you suggest a way of doing that?

I also found net adapter's
subsystem_vendor 0x8086
subsystem_device 0x0010
and
vendor 0x8086
device 0x24fd
But those seem to be only PCI IDs

As for the second suggestion, yeah, setting up sleep hook will probably work, but I'd like to have my headphones reconnected after suspend and this is kinda hacky, so I'll use it in case nothing else works.

Type "8087:0a2b" into google… (w/ quotes)

Since you unlikely(?) want to block usb from acpi wakeup, I'd go for the sleep hook. You can handle the resume there just fine (unblocking the rfkill or re-binding the device, whatever works itfp)
The BIOS probably wakes on BT events because of BT keyboards and why the headset fires permanently, I've no idea.

Thanks for your help.
So I ended up with this solution

systemd-service

[Unit]
Description=Bluetooth sleep hook
Before=sleep.target
StopWhenUnneeded=yes

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=-/usr/local/bin/on-sleep-bluetooth.sh 'sleep'
ExecStop=-/usr/local/bin/on-sleep-bluetooth.sh 'wakeup'

[Install]
WantedBy=sleep.target

And a script

#!/bin/bash

DEVICE_MAC=10:4F:A8:3C:00:BB
STATE_FILE=/tmp/bt-device-$DEVICE_MAC-suspend

function get_device_status {
  echo `bt-device -i $1 | rg -o 'Connected: (\d?)' -r '$1'`
}

function read_file_or {
  echo `cat $1 2> /dev/null || echo $2`
}

function status_change {
  if [ "$1" == "sleep" ]; then
    local device_status=`get_device_status $DEVICE_MAC`
    echo $device_status > $STATE_FILE
    if [ "$device_status" = "1" ]; then
      <<<"disconnect $DEVICE_MAC" bluetoothctl &> /dev/null
      sleep 3
    fi
  elif [ "$1" == "wakeup" ]; then
    local device_status=`get_device_status $DEVICE_MAC`
    local was_active=`read_file_or $STATE_FILE "0"`
    if [ "$was_active" == "1" ]; then
      <<<"connect $DEVICE_MAC" bluetoothctl &> /dev/null
    fi
  fi
}

status_change $1

If anyone knows of a better solution I'll gladly accept.
