I have problems pairing my Bose NC 700 headphones on Ubuntu 18.04 LTS via bluetooth. Every time I turn them on, they continue to connect and disconnect and don't work. I need to go to the bluetooth configurations and click on "remove device", then pair them again. Then they will work until I turn off the laptop or don't use them for some time.
Sometimes, using "systemctl restart bluetooth" helps. Is there a way to fix that permanently?
You might have interference between WiFi and Bluetooth (which most often affects WiFi). Please try a few things and report what you find/output info in the question.
Disabling WiFi. If this solves your problem, then depending on the adapters you have, a suitable configuration is possible.
