dmesg | grep Bluetooth gives [ 4967.683179] Bluetooth: hci0: BCM: patch brcm/BCM43142A0-0a5c-21d7.hcd not found
I don't have a Windows installation I can get files from
From lsusb Bus 002 Device 005: ID 0a5c:21d7 Broadcom Corp. BCM43142 Bluetooth 4.0
apt-get shows bcmwl-kernel-source is already the newest version
