Adaptador Bluetooth Broadcom BCM43242A0 não detectado no Ubuntu 18.04

1

Meu laptop tem um adaptador Bluetooth Broadcom BCM43242A0 que não funciona com o Kubuntu 18.04.

lsusb | grep Bluetooth 
Bus 002 Device 004: ID 0a5c:216c Broadcom Corp. BCM43142A0 Bluetooth Device

Eu já tentei consertá-lo baixando o firmware de link e copiei para /lib/firmware/brcm/BCM.hcd porque a saída de

dmesg | grep bluetooth

foi

[ 12.314809] bluetooth hci0: Direct firmware load for brcm/BCM.hcd failed with error -2

Depois disso, o adaptador bluetooth não é mais reconhecido nas configurações do sistema - > Bluetooth e dmesg | grep bluetooth não dão retorno. Saída de

uname -r; lsusb; lspci -nnk | grep -iA2 net; rfkill list all; hciconfig -a; dmesg | egrep -i 'blue|firm'

é

Eu não tenho ideia do que isso significa, mas do link eu entendi que isso bug foi corrigido com um novo kernel linux. Minha versão do kernel é 4.15.0-22-genérica, mas o problema ainda persiste. Como posso obter o bluetooth funcionando?

Etapas para corrigir:

  1. Acesse repo winterheart / broadcom-bt-firmware e faça o download do arquivo BCM43142A0-0a5c-216c.hcd (de acordo com o seu Chipset Bluetooth).
  2. Mova esse arquivo para /lib/firmware/brcm with name BCM.hcd
  3. Desligue e ligue o computador

PS Isso também pode funcionar para outros adaptadores broadcom , só é necessário obter o .hcd file: grep Dispositivo Bluetooth e < strong> ID com o comando lsusb | grep Bluetooth .
