T530 Ubuntu 14.04.3 LTS Broadcom Bluetooth BCM20702A1 doesn't work because firmware is not found

The firmware for the Broadcom Bluetooth BCM20702A1 firmware file does not exist. I have filed a Ubuntu bug report here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1065400 at entery #163

 

My Lenovo T530 Bluetooth does not work like so many others that have been reported. I am running
Ubuntu 14.04.3 LTS 64 bits,
kernel 4.4.0-75-generic,
Broadcom Bluetooth BCM20702A1 (001.002.014) build 0000,
Latest BIOS: LENOVO 2359CTO/2359CTO, BIOS G4ETA7WW (2.67 ) 08/24/2016

My dmesg error is:
bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0a5c-21e6.hcd failed with error -2
Bluetooth: hci0: BCM: Patch brcm/BCM20702A1-0a5c-21e6.hcd not found

 

The bluetooth will not work and has not worked for a very long time due to this problem.

Re: T530 Ubuntu 14.04.3 LTS Broadcom Bluetooth BCM20702A1 doesn't work because firmware is not found

In terminal do

wget https://www.dropbox.com/s/p6h7ho21fct2pzb/fw-0a5c_21e6.hcd
sudo cp fw-0a5c_21e6.hcd /lib/firmware/brcm/BCM20702A1-0a5c-21e6.hcd
sudo modprobe -r btusb
sudo modprobe btusb

Enter one line at a time and it should function
