[SOLVED] +(arm64) how disable wifi+bt?

hello ,

have installed the devuanpi for raspi 4/
am enquiring on how to disable the wi/fi and bt/card since i am not using it and it interferes with my concentration.

on raspios there is

/boot/config.txt

dtoverlay=disable-wifi
dtoverlay=disable-bt

how would it be handled on devuanpi?

thanks.

I expect it to be done in the same way.

Remember: Devuan is Debian but without systemd.

I opened up rpi-4-devuan-daedalus-6.1.93-arm64-ext4-2025-09-22-0257.img and mounted it.
The BOOT partition has a file named config.txt which includes what you are looking for:

--- snip ---
# enable uart
enable_uart=0

# disable wifi and bluetooth
#dtoverlay=disable-wifi
#dtoverlay=disable-bt

# remove test rainbow
disable_splash=1  
--- snip ---

Is there no config.txt file in your Devuan RPi installation?

Best,

A.

Not if it actually boots.

I don't think a RPi would boot without a config.txt file.

Have you checked elsewhere on the drive?
eg: /boot/firmware/*?

Best,

A.

thanks,

it is there, just someplace else.

solved by =menu-config which lets easily edit config.txt and saves

/boot/broadcom/config.txt

would be nice if there were toggle in Network section to activate/deactivate also the WiFi/Bluetooth (most probably needed separately)
