Removing beacon mode set with NRF.setScanResponse

Ahh, yes. It's a bit frustrating because of the way NRF.setAdvertising was implemented originally - and then I was stuck trying to be backwards compatible.

Try this:

var bUrl = "stackoverflow.com"; // Updated from Node-Red
  
  function updateAdv() {
    var data = [JSON.stringify(Puck.light().toFixed(3) * 1000), Math.round(E.getTemperature())];
    console.log(data);
    NRF.setAdvertising([
        NRF.getAdvertisingData({},{manufacturer: 0x0590, manufacturerData:data}),
        require("ble_eddystone").advertise(bUrl)­
        ], {interval:1000});
  }
  updateAdv();
  setInterval(updateAdv, 5000);
