Chances are you have so many advertising packets being received that it can't output the characters fast enough over BLE. Hence it not appearing to stop - it probably did stop but there was such a backlog it was taking ages.
The sample code definitely does work, but just not if you have a lot of devices or devices that advertise quickly
If you want to use
setScanrather thanfindDevices, make sure you can handle the data fast enough - for instance by just writing everything into an array (arr[d.id]=d)
