So it seems it's actually working fine albeit the strange mac addr, no
idea what I was trying before, although there's an error about loading
firmware:

[ 31.035291] Bluetooth: hci0: BCM: chip id 94
[ 31.035801] Bluetooth: hci0: BCM: features 0x2e
[ 31.037483] Bluetooth: hci0: BCM43430A1
[ 31.037498] Bluetooth: hci0: BCM43430A1 (001.002.009) build 0000
[ 31.037694] bluetooth hci0: Direct firmware load for
brcm/BCM43430A1.hcd failed with error -2
[ 31.037704] Bluetooth: hci0: BCM: Patch brcm/BCM43430A1.hcd not found

By adding a firmware [1] to the location it actually now stops
working, although shows up with a hciconfig, and had the following
errors.

[ 26.078038] Bluetooth: hci0: BCM: chip id 94
[ 26.096797] Bluetooth: hci0: BCM: features 0x2e
[ 28.130753] Bluetooth: hci0 command 0x0c14 tx timeout

Thanks,
Peter
