I'm looking for advice here. There is one screening rule that does help: Is that a way you can program the device that *ENSURES* without any doubt, that it will never emit energy off the transmitter? If the answer is no, you are not to add an rfkill controller. It is that simple (at least with the current rfkill core). If the answer is yes, then you can consider adding an rfkill controller. > If the answer is "yes", would the following semantics be right for > the disabled state ? > > - we de-associate > - we stop scanning > - all ioctls still work as usual, but they have no effect on > association and scanning until rfkill re-enables the device If your rfkill controller has been set to "block the radio", you must NOT allow any energy to be emmited by the transmitter.
