[SOLVED] How to disable bluetooth?

Hi, my HW does not contain bluetooth module at all, but if I use tcpdump, this appears in dmesg:

[944767.277399] Bluetooth: Core ver 2.22
[944767.277452] NET: Registered PF_BLUETOOTH protocol family
[944767.277455] Bluetooth: HCI device and connection manager initialized
[944767.277714] Bluetooth: HCI socket layer initialized
[944767.277719] Bluetooth: L2CAP socket layer initialized
[944767.277725] Bluetooth: SCO socket layer initialized

root@mybox ~ # lsmod | grep blue
bluetooth             937984  0
ecdh_generic           16384  1 bluetooth
crc16                  16384  1 bluetooth
rfkill                 36864  2 bluetooth

How can I get rid of it? I thought of removing/disabling the module, but I don't know if that's the right way?

blacklisting a kernel module is described here without charge :-)

Re: [SOLVED] How to disable bluetooth?

Thank you for the answer. Yes, I can block the kernel module - I did it in Debian. I just wanted to see if I was doing it in a complicated or non-standard way. I wanted to see if there was another way to do it.

Thanks
