O hardware Bluetooth não é detectado após a atualização para o Ubuntu 15.10

Question

Eu costumava ter janelas no mesmo laptop e o Bluetooth funcionava bem, mas depois da instalação do Ubuntu 15.10, ele não reconhece o hardware, o que posso fazer para obter o driver adequado?

Esta é a minha informação de hardware na série Acer R3 - 431.

Answer 1

No terminal, digite lspci e cole os resultados para que a comunidade possa ajudá-lo com o driver específico. Há uma chance de você não ter um cartão compatível, como no meu caso. Acabei pedindo um cartão wifi / bt compatível para o meu.

Portanto, parece que você tem a Qualcomm Atheros QCWB335, que tem o coexistente bt e wireless no mesmo cartão. A boa notícia é que sua placa é suportada pelo kernel usando o driver ath9k. A parte não tão boa, mas ainda boa, é que, para habilitar bt, você deve habilitar manualmente a coexistência no cartão. Se tudo estiver correto, e com alguma sorte, rodar modprobe ath9k btcoex_enable=1 no terminal ativará a coexistência e a executará.

$$ Como eu faço isso? Você pode me explicar?

* no terminal, basta digitar modprobe ath9k btcoex_enable=1 e apertar enter.
