Unexpected disconnections

[haroal]

Sometimes, mostly when using my built-in Bluetooth controller, I have unexpected disconnections, right after connection.
The only solution found to be able to connect again is to reset the controller by powering it off/on...
If I run dmesg I have :

[700313.698910] Bluetooth: hci0: link tx timeout
[700313.698921] Bluetooth: hci0: killing stalled connection c4:f0:a5:e6:8a:91

I have no idea on how to solve that and it seems that I am not the only one : noble has a lot of issues about this error (without solution)...
