Marcel,

So it's pulling the right firmware file for my device, but It just
hasn't been released yet?

I know with the Wi-Fi firmware, the ath10k devs had python scripts to
extract the firmware binaries from the Windows drivers (mentioned in
here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1383184). Has
anyone done that before with the bluetooth firmware, or do you typically
just wait for atheros/qualcom to release official ones?
