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

My list of files in /lib/firmware/brcm is:
bcm4329-fullmac-4.bin brcmfmac43242a.bin brcmfmac4350-pcie.bin
bcm43xx-0.fw brcmfmac4329-sdio.bin brcmfmac4354-sdio.bin

Notice there is no *.hcd file... or anything for a 20702*

Note that I do NOT have blueman installed.

I am unable to pair with a mobile phone. The dmesg log repeats the firmware loading error every time I attempt to use the Gnome Bluetooth desktop utility.

I have spent a lot of time chasing posts on related Broadcom bluetooth errors here and elsewhere without success. My bluetooth has not be operational for a VERY long time!

When will we get a fix for this?
