[SOLVED] Specific Bluetooth device no longer connects

I was previously using bluetoothctl to connect to my wireless headset, but now it doesn't connect anymore. There is nothing wrong with the headset; it connects to my phone just fine.

Device B4:4B:D2:94:62:D9 Ziggy is my phone and connects successfully.
Device EB:06:EF:4A:66:81 Mpow H7 is the headset to which I am trying to connect. It worked previously, and I haven't made changes to configurations. I did run pacman -Syu after the issue occured, however.

The Bluetooth service is mostly running fine, but there is a series of errors when I try to connect.

I've followed this guide but my error message is something different: https://wiki.archlinux.org/index.php/Bl … g_does_not

I'd be happy to provide additional information. Thanks in advance.

Edit/Solution

All I had to do was remove from paired devices and repair. I really should have thought of that earlier. Oh well. I hope this post helps someone.

Re: [SOLVED] Specific Bluetooth device no longer connects

Should we count this as fix?

Basically, I have to remove it and pair every time when I switch from windows to linux (dual booted system). Happy to help anyone who wish to dig this further.

Have you found a solution? Same here with pixel buds pro. I am tired of re-pairing them twice a day.

Re: [SOLVED] Specific Bluetooth device no longer connects

When dual booting you are sharing one BT adapter MAC address across different systems which can lead to confusion of the other end, see https://wiki.archlinux.org/title/Blueto … ot_pairing for how to remedy and synchronize the setups so this can be logically shared.
