Using a puck.js device to receive and display temperature status obtained from another puck.js

It should be as simple as mashing the two examples above together...

Just modify the second example to:

var currentTemp = 0;
function getTemp() {
  NRF.findDevices(function(devices) {
    var found = false;
    for (var i in devices) {
      if (devices[i].name!="Puck.js e782") continue;
      var d = E.toString(devices[i].data);
      // index of 0x1809 in advertised data
      var idx = d.indexOf(String.fromCharCode(0x09,0x18));
      if (idx>=0) {
        currentTemp = d.charCodeAt(idx+2);
        found = true;
      }
    }
    if (found) {
      NRF.setAdvertising({
        0x1809 : [currentTemp]   // <----  code added here
      });
      digitalPulse(LED2,1,50); // green = good
    }  else
      digitalPulse(LED1,1,50); // red = bad
  }, 2000 /* receive for 2000ms */);
}
// look once a minute for temperature
setInterval(getTemp, 60000);
