To really lock it down right now you're best off adding the code:
NRF.on('connect',function(addr) { if (addr!="69:2d:94:d0:9d:97 public") NRF.disconnect(); });
With your connecting device(s) addresses.
You could also try NRF.setWhitelist(true) but this hasn't been well tested
NRF.setWhitelist(true)
