Interesting discovery controlling my Thermostat project.

I tried to use passkey in a simple case:

NRF.setSecurity({passkey:"123456", mitm:1, display:1});

var  on = false;
setInterval(function() {
  on = !on;
  LED1.write(on);
}, 500);

I expected to get a prompt from the IDE when I tried to reconnect, but it reconnected without issue. I did notice this comment:

As of Espruino 2v02 (or 'cutting edge' builds), you can set a static Passkey for Espruino:

I'm currently using 2v01.56 and I don't see any builds that are greater than 2v01. What am I missing?
