For my laptop, which is an x230 model 2325KZ5, I have:
Bus 001 Device 004: ID 0a5c:21e6 Broadcom Corp. BCM20702 Bluetooth 4.0 [ThinkPad]
The file which I needed to use was brcm/BCM20702A1-0a5c-21e6.hcd as noted above. That is the only file needed to fix my issue.
The post I linked to is for 0a5c:21e8 that I noted above.
