Por que o Blutooth não se conecta?

A unidade Bluetooth pode encontrar, mas não se conectar a outros dispositivos no Debian Testing (9.0 Stretch). O Bluetooth funciona bem com um sistema operacional diferente. As configurações do BIOS permitem o uso sem fio.

Os seguintes pacotes foram instalados:

  • bluez-firmware
  • broadcom-sta-common
  • broadcom-sta-dkms
  • broadcom-sta-source
  • firmware-brcm80211
  • firmware-misc-nonfree

Você está faltando firmware para o bluetooth. 

cd /lib/firmware/brcm
sudo wget https://github.com/winterheart/broadcom-bt-firmware/raw/master/brcm/BCM20702A1-13d3-3404.hcd
sudo modprobe -r btusb
sudo modprobe btusb

Veja se funciona
