Power management/ puck's button?/ getting started links

I think this is working OK. Is the advertising interval fixed at around 2 secs?

setWatch(
  function() {
    NRF.wake();
    LED1.write(true);
    setTimeout(function() {
      LED1.write(false);
      setTimeout(function() {
        NRF.sleep();
      },60*1000); // 1 minute
    },50);
  },
  BTN,
  {
    edge:"rising",
    debounce: 50,
    repeat: true //??
  }
);
NRF.sleep();

The button seems super-sensitive. I checked that the device is reassembled correctly. Picking it up appears to activate it.
