Removing beacon mode set with NRF.setScanResponse

NRF.setScanRespose doesn't return anything, so what you're doing is effectively:

NRF.setScanResponse(require("ble_eddysto­ne").get("goo.gl/B3J0Oc"));
NRF.setAdvertising([
            NRF.getAdvertisingData({},{manufacturer:­ 0x0590, manufacturerData:data}),
            undefined
   ], {interval:1000});

Which is just:

NRF.setScanResponse(require("ble_eddysto­ne").get("goo.gl/B3J0Oc"));
NRF.setAdvertising({},{manufacturer:­ 0x0590, manufacturerData:data,interval:1000});

Actually I made the same mistake with the example code - using advertise instead of get. It should be:

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").get(bUrl)­
        ], {interval:100});
  }
  updateAdv();
  setInterval(updateAdv, 5000); 

I just tried this and it works for me. Your inability to connect is most likely because the interval was 1000ms - BLE broadcasts on 3 frequencies in turn, and it's also alternating advertising packets so a computer trying to connect is only seeing an advertising packet every 6 seconds - pretty much any connecting computer will time out connecting unless you're very lucky.

Hope that helps!

Just to add [JSON.stringify(Puck.light().toFixed(3) * 1000), Math.round(E.getTemperature())] is probably not what you want... It's creating a String of ascii characters with quotes around it, which is then being converted to a series of bytes (which could be variable length).

It's probably best to just pack it into a byte with: [Puck.light()*255, Math.round(E.getTemperature())] (the conversion to integer gets done automatically).
