Hey Everybody,

I’m looking to have Gnu-Radio (or some other program) recognize specific OOK codes on 433 mhz. When those codes are received I need them to display A message on a note-pad or on screen somewhere and then return down.

Any idea how to accomplish this? Just a nudge in the correct direction would help greatly!
