Firmware is missing:

[ 3.479417] bluetooth hci0: Direct firmware load for brcm/BCM-0a5c-6410.hcd failed with error -2
[ 3.479421] Bluetooth: hci0: BCM: Patch brcm/BCM-0a5c-6410.hcd not found

I'm having same issue. Is the directory mentioned part of linux-firmware ? I think the directory where the file is missing is /lib/firmware/brcm/ ?

After some digging, as suggested in says:
Following I downloaded the missing firmware file (thanks @ZombieMeat) at Dropbox and copied it to /lib/firmware/brcm/
Actually that worked. Attaching file that fixed it

Updated firmware with latest one (version 481).

Same as last one, decompress it, and ensure the permissions are correct on:

-rw-r--r-- 1 root root 54734 may 19 21:22 /lib/firmware/brcm/BCM-0a5c-6410.hcd

When loaded you should see something this on 'dmesg' like:

[ 6828.577574] Bluetooth: hci0: BCM (001.001.005) build 0481

After more digging on how this works, looks like several broadcom chips have similar problems to load this type of files (bug #1129865, bug #1065400). According to a question in askubuntu (also best place of how the procedure to produce this .hcd files) , there are some legal problems that don't allow this firmware files to be added to the Ubuntu installation

Thanks a lot to @bertusrex on for getting into windows and getting us the firmware file.

Looks like nowadays you can download this firmware files from microsoft site? (this can enable us to automate this installation somehow on Ubuntu, AFAIK).

1. a Github site that generates this files
2. the Microsoft URL:
