Bluetooth не обнаруживает никаких устройств - Dell XPS 13 (16.04) [ Решено]

Я просмотрел другие решения и темы для этой проблемы, но ни одно из них не помогло мне.Я использую Dell XPS 13 для подключения своих новых наушников Jaybird X3. Пока ноутбук не может обнаружить ни наушники, ни мобильное устройство.

РЕДАКТИРОВАТЬ: Все устройства находятся в режиме обнаружения. Я попытался переустановить Bluetooth, используя этот ответ https://askubuntu.com/a/776812/701563 , и это не сработало. Я не уверен, почему, но теперь BLueman Assistant говорит: «Адаптеры не найдены».

Я выполнил несколько команд в терминале и получил следующие результаты:

$ sudo service bluetooth status
