Can't locate device by Name - solved with longer scan - Tilt

Hi, a bit of progress. By increasing the scan I now can find the device:

NRF.findDevices(function(devices) {
  console.log(devices);
}, 30000);

[

// Apple TV
  BluetoothDevice: {
    "id": "08:66:98:c6:75:50 public",
    "rssi": -90,
    "data": new Uint8Array([2, 1, 26, 10, 255, 76, 0, 16, 5, 1, 16, 104, 16, 8]).buffer,
    "manufacturer": 76,
    "manufacturerData": new Uint8Array([16, 5, 1, 16, 104, 16, 8]).buffer
   },
// Red Tilt
  BluetoothDevice: {
    "id": "04:a3:16:9a:af:cc public",
    "rssi": -92,
    "data": new Uint8Array([26, 255, 76, 0, 2, 21, 164, 149, 187, 16, 197, 177, 75, 68, 181, 18, 19, 112, 240, 45, 116, 222, 0, 62, 3, 239, 197]).buffer,
    "manufacturer": 76,
    "manufacturerData": new Uint8Array([2, 21, 164, 149, 187, 16, 197, 177, 75, 68, 181, 18, 19, 112, 240, 45, 116, 222, 0, 62, 3, 239, 197]).buffer
   }
 ]

I can connect by service, by adding the timeout of 20000:

var gatt;
NRF.requestDevice({ timeout: 20000,filters: [{ "services": [
     'a495ff10-c5b1-4b44-b512-1370f02d74de'
     ]}] }).then(function(device) {
   console.log(device);
  return device.gatt.connect();
 }).then(function(g) {
  gatt = g;
  return gatt.getPrimaryService("a495ff10-c5b1-4b­44-b512-1370f02d74de");
}).then(function(service) {
  console.log({service:service});
}).then(function() {
  gatt.disconnect();
  console.log("Done!");
});

=Promise: {  }
BluetoothDevice: {
  "id": "04:a3:16:9a:af:cc public",
  "rssi": -88,
  "data": new Uint8Array([2, 1, 6, 17, 6, 222, 116, 45, 240, 112, 19, 18, 181, 68, 75, 177, 197, 16, 255, 149, 164, 2, 10, 0]).buffer,
  "services": [
    "a495ff10-c5b1-4b44-b512-1370f02d74de"
   ],
  "manufacturer": undefined, "manufacturerData": undefined }

1. The getPrimaryService never gets fulfilled. Not sure what is going on here? There does not seem to be a way of adding a timeout?

2. The manufacturer data in the first code block - seems to wrong - as 76 is apple and the previous devices is an apple tv- and in the 2nd block of code - it is undefined for the Tilt - so I'm wondering if the previous values are getting set?

3. What is data in BluetoothDevice: structure?

4. Can the device name be included in the BluetoothDevice: structure?
