broadcom 802.11n network BCM43430/0 not recognized by the system

I have an old windows tablet and since it was slow I decided to install Arch Linux in it, I tried many distros but were unable to recognize the adapter I ended up installing arch offline... but unfortunately, I am still unable to get the system to the recognize the wireless network adapter tablet specs:
intel atom z8300 2GB of ram 32GB storage
from my windows hwinfo up I got that the wireless adapter was the Broadcom 802.11n SDIO and in windows wi-fi  internet works fine
I read the wiki: https://wiki.archlinux.org/title/broadcom_wireless but there were none B43 in the output of dmesg
here's the content of dmesg:
https://pastebin.com/G1HA1xfq
EDIT: the mac address of the device is E0-76-D0-35-3B-69

Re: broadcom 802.11n network BCM43430/0 not recognized by the system

There is no corresponding firmware file for your model of the bcm43430 BT/WiFi combo chip:

[    7.159807] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43430a0-sdio for chip BCM43430/0
[    7.159953] brcmfmac mmc0:0001:1: Direct firmware load for brcm/brcmfmac43430a0-sdio.PLAISIO COMPUTERS SA-CherryTrail.bin failed with error -2

The file "brcmfmac43430a0-sdio.PLAISIO COMPUTERS SA-CherryTrail.bin" doesn't seem to exist. I don't know if it's possible or advisable to force the driver (brcmfmac) to load another file instead.

There is no corresponding firmware NVRAM config file for your model of the bcm43430 BT/WiFi combo chip:

[    7.159807] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43430a0-sdio for chip BCM43430/0
[    7.159953] brcmfmac mmc0:0001:1: Direct firmware load for brcm/brcmfmac43430a0-sdio.PLAISIO COMPUTERS SA-CherryTrail.bin failed with error -2

The file "brcmfmac43430a0-sdio.PLAISIO COMPUTERS SA-CherryTrail.bin" doesn't seem to exist. I don't know if it's possible or advisable to force the driver (brcmfmac) to load another file instead.

thanks for the advice I EDIT: it seems I need to install a missing firmware file, I will be looking into it tomorrow but if anyone has an idea about what that file is , post it here
