disable wake on bluetooth? (lemmy.world)

When I turn on my headphones, my oled deck turns on. Neat, but unwanted when I'm using my headphones for other things, like my zoom meeting for work causing Dave the Diver sounds to come out of my headphones. How can I turn that off without disabling Bluetooth every time I put the deck to sleep?

Try putting a script like this in /lib/systemd/system-sleep/. Make sure it is executable.

#!/bin/sh

case $1 in
	pre)
		bluetoothctl power off
		;;

	post)
		bluetoothctl power on
		;;
esac

What I said before, looks like a dead end.

~~Start with "cat /proc/acpi/wakeup" and "lspci". My LCD deck doesn't have the new BT chip with wakeup, but I think it might go like this~~

~~Look at lspci, find the Bluetooth there (Maybe it's just part of the wifi?). Note its PCI address, and find a value in /proc/acpi/wakeup that corresponds to that. Take the name from the first column of /proc/acpi/wakeup, and do something like "echo GPPn | sudo tee /proc/acpi/wakeup" . If this works, then you'll want to (a) make a slightly more permanent version of this per the arch wiki, and (b) remember to undo that when Valve finally gets around to doing a proper control for this.~~

I do not see a BT device in lspci, and the Network Adapter PCI address doesn't show i /proc/acpi/wakeup,

I tried to create a systemd unit file that would issue an rfkill on bluetooth on suspend, and then re-enable it on resume, but that didn't work either. Interestingly, if I do systemctl stop bluetooth the bluetooth service stops, and then immediate starts again!

Oop. Look up. I changed the parent post, maybe this time it'll work?
