I used to have windows on the same laptop and Bluetooth worked fine, but after Ubuntu 15.10 installation, it doesn't recognize the hardware, what can I do to get the proper driver?

This is my Hardware information on Acer R3 - 431 series.

In terminal, please type lspci and paste the results so the community can help you with the specific driver. There is a chance that you may not have a compatible card, as it was in my case. I ended up ordering a compatible wifi/bt card for mine.

So it appears you have Qualcomm Atheros QCWB335, which has the bt and wireless coexisting on the same card. The good news is that your card is supported through the kernel using ath9k driver. The not so good part, but still good, is that to enable bt, you must manually enable the coexistence on the card. IF all is correct, and with any luck, running modprobe ath9k btcoex_enable=1 in terminal will enable coexistence and get it running.

$$ How do i do that ? $$$ can you please explain me ?

*in terminal just type modprobe ath9k btcoex_enable=1 and hit enter.

  • Please also identify the brand/model of laptop. This is a Bluetooth driver issue, not something specific to Ubuntu 15.10.
