Problem z podłączeniem głośników przez Bluetooth

[NoRobot]

Kupiłem sobie głośniki https://allegro.pl/oferta/glosniki-komputerowe-kruger-matz-bluetooth-usb-9168826578. Na laptopach Lenovo nie było problemów z ich podłączeniem w Archu.

Kupiłem sobie nowego laptopa https://allegro.pl/oferta/hp-745-g2-amd-7350b-16gb-320gb-win-10-hd-14cali-9350899178 i zaczęły się schody. Za każdym razem kiedy system widział te głośniki, nie dawały się one podłączyć przez Bluetooth. Potem Bluetooth w ogóle znikał z systemu (brak adapterów).

Ściągnąłem sobie obraz iso Fedory33 i nagrałem go na pendrive. Po starcie systemu live okazało się, że natychmiast podłączył się do głośników. Zainstalowałem więc Fedorę. Niestety scenariusz archowy i tutaj się powtórzył. Kilka razy system widział głośniki, ale nie mógł się do nich podłączyć. Obecnie „brak adapterów".

# systemctl start buletooth.service
Failed to start buletooth.service: Unit buletooth.service not found.
# systemctl disable buletooth.service
Failed to disable unit: Unit file buletooth.service does not exist.

Proszę o pomoc w rozwiązaniu tego problemu.

Dodam, że system  Windows 10 łączy się bez problemu z tymi głośnikami.

Prawdopodobnie brakuje Ci  odpowiedniego firmware, wejdź do katalogu /lib/firmware/brcm i w nim wykonaj polecenia:

wget https://github.com/winterheart/broadcom-bt-firmware/raw/master/brcm/BCM20702A1-0a5c-21fb.hcd

Na Forum Archa przez długi czas ten temat był rozwiązywany bez powodzenia. Tobie to się udało błyskawicznie.  Dziękuję :-)

Ja wiedziałem, że brakuje sterowników, ale jakich?...
