I really don't understand what you are searching for...
Ignore him sounds likea troll or bot.

Regarding the firnware your using. Just install linux-firmware package and it should with fine.
Regarding the Bluetooth i replied and that thread you need to use a better bt firmware file. I will share the link with you soon.

Here these are well maintained version.

AP6255 = brcmfmac43455

Use the one from here for better stability.
