    Bluetooth not working

    Hi,

    I have a Lenovo Z570 with Ubuntu 16.04 and, while wireless works, Bluetooth doesn't.

    The manufacturer's guide shows the following Bluetooth specs:

    "BT2.1 + EDR CyberTan/USI module"

    and

    "Bluetooth card, BT2.1 + EDR, Fcn BCM92070 BT2.1 EDR Flash U NB".

    the Bluetooth manager says "No Bluetooth adapters found".

    Thanks for your help.

    p.s. below is the output of diagnostic commands requested on a similar thread:

    $dmesg | grep iwl

    Re: Bluetooth not working

    Have you tried looking for a driver? Any reason you chose to go with 16 if 20 is available?

    Re: Bluetooth not working

    the laptop is 8 years old, & I'd rather not upgrade to Ubuntu 20 as newer releases typically require more RAM & CPU for optimal performance.

    at this point, I'd like to find out why the Bluetooth hardware isn't even being detected, or appears to not be detected.
