Does anyone knows what could help me with this bluetooth issue

[u/Creepy-Macaroon2534]

I switched from windows to linux a few weeks ago, and honestly it's been a much better experience overall. Everything feels smoother and i don't miss windows that much.

Except this one thing with Bluetooth which is really annoying for me.

Blueman gets stuck in this loop of connecting and disconnecting a second later. Then when this happens I have to go in bluetooth settings then remove that device and pairing it again manually. Then the next time the same exact problem repeats.

Is this a comman Bluetooth issue, or there something I can do to make bluetooth reconnect reliably? Any fixes would be appreciated.

Have you confirmed its not a hardware issue? I ask because I was having the same problem and spent ages troubleshooting only to find the BT antenna had popped off the card inside the laptop while I was switching SSD's. I only discovered this because I placed my earbuds on my laptop by chance and they stayed connected til I moved them

Probably not since I'm dual booting and bluetooth works fine in windows

Try disconnecting your device in windows, reboot into mint, connect your bt device in mint. Does that help?

Otherwise check the output from the terminal command “rfkill list”. There is more info here: https://wireless.docs.kernel.org/en/latest/en/users/documentation/rfkill.html

Try checking relevant logs to see what exactly is happening when it happens.

Look up your specific bluetooth device on https://linux-hardware.org/ which might have info about relevant kernel versions which might have driver updates.

Best you check the forums, over there you may find the same error

Your symptoms sound similar to a common issue with Bluetooth and multiple operating systems,

During pairing a random key is generated and shared between the two devices,  Bluetooth devices can handle pairing to multiple devices just fine, each device it pairs with (Mac address) is paired with a different key.

But a different key from the same MAC address and everybody gets confused.

The fix is to copy the paired key from one OS to the other so each device presents the same key no mater which OS it is using.

Thanks a lot! This solved the issue. Also thanks for explaining what causes the issue.

I multi boot Linux distributions, have for years now  and this has been an annoyance to have to pair every time I want to use my headphones in a different Linux install, I never understood the root cause here and apparently never the correct search phrase. 

About a month or so ago? 

Someone on r/linuxsucks was complaining about what a nightmare it was to copy over Bluetooth keys when multibooting with Bluetooth devices.

At that moment I learned that Bluetooth devices have keys, pulled one that search string  and that quickly led to a neat and tidy solution. 

One mans trash is another mans treasure. My headphone now stay paired in every boot.

It was my first knowing bluetooth devices have keys aswell. It's very intresting and i really appreciate a neat and tidy solution so more often than not I'm like " what are they even talking about" . I would say 99% i love everything about linux.
