Ubuntu 20.04 Bluetooth BCM20703A1 (001.001.005) build 0000

[julianpacker]

Hi winterheart, thanks for looking after these packages.

I'm having some trouble getting my bluetooth to work. I originally had this error:
direct firmware load for brcm/BCM20703A1-0a5c-6410.hcd failed with error -2

After I got that file from your repository and put it in /lib/firmware/brcm I got the following error:

dmesg | grep -i bluetooth

I've read through the other issues and it seems build 0000 is a silent error.

I don't think I have a wifi+Bluetooth device, and I'm not sure what else to try here. Do you have any info about this issue?

Hello.

I think you need to WiFi module get working with brcmfmac driver as described in README. I guess this is another combined WiFi+Bluetooth device.
