how to disable bluetooth

[CeDeROM]

hey, how can i disable bluetooth in freebsd (9.1)?

my device is visible to other devices whethever i switch the radio button,
also the radio button seems to be the only waynto disable my computer from
being visible to other devices...

i hwve tried to disable bluetooth and ubt in loader.conf and various
serives in rc.conf but still my computer was visible to other devices. i
dont want it to be visible to other bluetooth computers but still i want to
have radio switched on to use wifi.

please advise :-)
