No description provided.

We would need:

• firmware-brcm80211
• wireless-regdb
• wireless-tools

[chombourger]

we also need to ship /lib/firmware/brcm/brcmfmac43430-sdio.txt
I extracted this file from the images provided by FriendlyArm:

it would even be better to name that file: /lib/firmware/brcm/brcmfmac43430-sdio.friendlyarm,nanopi-r1.txt

/lib/firmware/brcm/brcmfmac43430-sdio.AP6212.txt works(scanning). Just renamed to /lib/firmware/brcm/brcmfmac43430-sdio.txt. That is what the driver expects.

it will first try the machine specific .txt file and fallback to the generic one if not found

Yes. I would prefer the one with board name as well.

Able to connect to my WiFi using nmcli
