Ubuntu 17.10 not detecting bluetooth mouse

Question

My Logitech bluetooth mouse worked in 17.04 until I did a fresh install of 17.10 on my Dell Inspiron, now it doesn't see it. Bluetooth is on and sees my iPhone.

Solution

Had the same problem after upgrade to 17.10. For my intel bluetooth adapter disabling bt_coex_active solved it.

It uses iwlwifi so adding the text above in /etc/modprobe.d/iwlwifi.conf disables it, you can do it in one line:

echo "options iwlwifi bt_coex_active=0"|sudo tee --append /etc/modprobe.d/iwlwifi.conf

then you should restart your computer or you can reload your wifi modules. Again in one line:

sudo rmmod iwlmvm iwlwifi && sudo modprobe iwlmvm

Where in the file should this be added?

The file does not need to be edited directly, the echo command will append the directive to the file.

I needed to restart the computer a second time after the last command for it to work.
