Description of problem:
Missing firmware for BCM20702A1 bluetooth chipset (Thinkpad T430
It is possible to correct it using the firmware extracted by the windows driver package.
You can copy BCM20702A1_001_002.014.1443.1453.hex from \windows\system32\driver from your windows installation and you can use hex2hcd (https://github.com/jessesung/hex2hcd) to convert it and copy it on /lib/firmware/brcm/BCM20702A0-0a5c-21e6.hcd
ERRATA: Sorry the correct file is /lib/firmware/brcm/BCM20702A1-0a5c-21e6.hcd
Does the b43-fwcutter tool work for this?
We cannot distribute firmware files that are not explicitly granted redistribution permissions. More specifically, we very rarely carry files in the linux-firmware package that are not in the upstream linux-firmware repository. Extracting it from a Windows driver and putting it into linux-firmware isn't something we are going to do, which is why the b43-fwcutter tool exists.
I have never used b43-fwcutter, sorry :(
Ok you have explained very well, thankyou
