Disable wifi and blueooth on Pi3

Postby tboooe » 29 Apr 2016, 23:32

Just got my Pi3 and starting messing around with Rune as a renderer on my network getting music from Minimserver. So far so good! Going to be adding Digi+ board soon. Here is my noob question...what is best way to disable Wifi and Bluetooth? I am after the absolute best sound quality so I want to disable all unnecessary services. The only thing I have found from another forum is to blacklist loading of the Wifi and Bluetooth drivers (see below). Is there a better way?

/etc/modprobe.d/raspi-blacklist.conf

#wifi
blacklist brcmfmac
blacklist brcmutil
#bt
blacklist btbcm
blacklist hci_uart

Hi tboooe,

Is there a better way?

Yes. Desolder the components :)

/etc/modprobe.d/raspi-blacklist.conf

The file already exists on your Pi, you only have to remove the #.

LoL @ hondagx35, is it really that bad? As soon as I heard about the built-in WiFi and Bluetooth I thought.... mmmmm no, not good.

Hi Andre,

The file is called /etc/modprobe.d/blacklist.conf
(because Arch and Raspbian often use different files and directories)

I think you have to create that file, if you do not have it already. For example open it in the editor:
Code: Select all
nano /etc/modprobe.d/blacklist.conf

then type or paste in what you want, and save it.

edit:

Also, see this post by Frank, the official answer to disabling the onboard wifi and bluetooth:

On my RPI3 the file is named: /etc/modprobe.d/disable_rpi3_wifi_bt.conf

Incidentally, the audio section of the pi is isolated from the networking hardware. As seen in another thread, people seem to be worried about this for no reason aside from voodoo/superstition. If the environment you're in has lots of RF interference, the board >may< pick it up, >if< its on a resonant frequency that either of the wireless modes run on, or the ethernet cable acting as an antenna.

I'm willing to bet that people listening in a double blind comparison between wireless turned on or off will not notice a difference.
If you notice a problem, then its worth investigating, however doing something based upon a worst-case-theory seems pointless to me.
