[SOLVED] Bluez can't detect bluetooth earbuds

It detects bunch of random devices just fine.
I had no problem connecting to my buds until i booted up windows, it stopped working after that.
buds are in pairing mode, but bluetoothctl scan on can't detect them.

Re: [SOLVED] Bluez can't detect bluetooth earbuds

Is fast startup disabled in Windows: https://wiki.archlinux.org/title/Dual_b … ibernation that's something you should minimally do on a dual boot regardless of anything else.

Assuming you paired your earbuds in Windows as well this can lead to logical complications since two different systems register with the same MAC address of the receiver, you might want to check/follow https://wiki.archlinux.org/title/Blueto … ot_pairing to properly share keys. Alternatively try to wipe your /var/lib/bluetooth and re-pair

Yes fast boot is disabled in windows.

Check if your user have access to /var/lib/bluetooth and at least one device paired. Try use sudo.

sudo ls /var/lib/bluetooth

correct me pls if i didn't understand
https://wiki.archlinux.org/title/Blueto … ot_pairing

sudo bt-dualboot -l

ERROR: No Bluetooth devices found!
Check if your user have access to /var/lib/bluetooth and at least one device paired. Try use sudo.

Re: [SOLVED] Bluez can't detect bluetooth earbuds

Solved by sudo rm -rf /var/lib/bluetooth/ and restarting everything
multiple times
