I paired a Bose 35 headset with my Lenovo T520 notebook (upgraded to Bluetooth 4.2). Once I switch off the headset, and later switch it on, the both do not reconnect again. The headsets reconnects to my S7 phone automatically, so does the notebook when it runs in Windows.
The workaround in CL is to disable the Bluetooth button in GNOME, toggle it back on, and once the headset shows up, to click on it and switch it back on so it says “Connected”.
This should happen automatic …
