Bluetooth não funciona no Ubuntu 15.04

Question

Eu instalei o Ubuntu 15.04 em um notebook DELL XPS 13 (modelo 9343, bios A03). Meu dispositivo bluetooth interno é detectado com hci, o ícone está na barra de tarefas, mas ao procurar por dispositivos bluetooth ele não encontra nada e ele próprio não pode ser encontrado. Eu estou anexando algumas informações. Sugestões são bem vindas.

Answer 1

Deve ser bem fácil

wget https://www.dropbox.com/s/r2pb41rhx65t9zi/BCM20702A0-0a5c-216f.hcd
sudo cp BCM20702A0-0a5c-216f.hcd /lib/firmware/brcm/
sudo modprobe -r btusb
sudo modprobe btusb

E o bluetooth deve funcionar

Em alguns dias, você deve conseguir sudo update-usbids e seu dispositivo Bluetooth deve ser identificado como bluetooth em lsusb
