Mini PC Z83 V (Ampak AP 6255 - brcm43455 - Combo Wifi BT) No Bluetooth

HardGeek

Hello at all,

I try to run BATOCERA on a Intel Z83 V. It works well but there is an issue with onboard combo wifi / bluetooth.

I have no wifi and no Bluetooth and so,

I can’t pair my bluetooth controler.

Or with Ubuntu, with the same config, bluetooth run wery well. (I don’t try wifi)

I think it’s missing something like driver or firmware…

Here is what i found with some command in SHH :

With the command dmesg | grep Blue

dmesg | grep Blue

Hi,

I try to add a missing files into /lib/firmware/brcm

I use the window who’s oppening with “F1” and with a usb key I past the missing files corresponding to my hardware in /lib/firmware/brcm

but when i reboot the computer, the files are still missing…

What’s wrong ? Do I miss something to save the change ?

I have searched a lot on Batocera to activate Bluetooth, but there is nothing to do, I will not be able to do it without your help. However, I managed to get wifi and bluetooth to work on Ubuntu 20.04.2.

Can anyone guide me to make these two functions work on Batocera as well?

J’ai pas mal cherché sur Batocera pour activer le Bluetooth, mais il n’y a rien a faire, je n’y arriverai pas sans votre aide. Par contre je suis arrivé à faire fonctionner le wifi et le bluetooth sur Ubuntu 20.04.2.

Quelqu’un pourrait me guider afin de faire fonctionner également ces deux fonctions sur Batocera ?

I don’t know if this is the right track but on Ubuntu there are 2 bluetooth profiles:

hci0: UART bus that works

hci1: SDIO bus which remains “DOWN”

On Batocera:

hci0: SDIO bus which remains “DOWN”

I think if I could get a UART profile on Batocera, I will be able to solve my problem.

an idea ?

Je ne sais pas si c’est la bonne piste mais sur Ubuntu il y a 2 profils bluetooth :

hci0 : Bus UART qui fonctionne

hci1 : Bus SDIO qui demeure “DOWN”

Sur Batocera :

hci0 : Bus SDIO qui demeure “DOWN”

Je pense que si j’arrivais à obtenir un profil UART sur Batocera, j’arriverai à résoudre mon problème.

une idée ?
