[SOLVED] Bluez spams in journal: Adv Monitor disconnected from D-Bus

When Bluez.Experimental flag is true (I need it to read headphones battery level) it spams to the journal messages like:

bluetoothd[398]: Adv Monitor app :1.803 disconnected from D-Bus

Just look at it:

139580! messages in a few days

Basically it logs each second or even faster.

I do want to have an abilities to read the battery status of my headphones (Galaxy Buds Pro) but obviously I really don't what to have that much spam in the journal.

The only thing I've changed in the /etc/bluetooth/main.conf is the Experimental flag. Everything else is commented out.

Bluetooth works normally. Battery status from experimental flag works too.

Why this can happen? Where should I look to investigate?
Or can I at least set LogLevel for Bluez? (couldn't find how to do this yet)?

Ok, I got it.
Honestly it's just too obvious and stupid.

I had an idea that these messages can be not and error messages but ignored it for some time...

But it's actually just each my requests for a battery status.

Each time I call:

bluetoothctl info $1 | awk -F '[()]' '/Battery Percentage/ {print $2}'

It logged the message to the journal.

I'm using it in polybar module I've wrote recently at 2 am... and it has default interval in 0.5s.

I'll increase it to a few minutes and it should be good

Hi Had a nearly identical issue but the spamming was caused by the bluetooth system tray applet. Disabling this made the messages go away for me.
