title: Is it possible to have dozens of active connections using Bluetooth Low Energy?
body: <p>I'm developing an app in which the smartphone should connect to a device via bluetooth. This device could be a Arduino or Raspberry Pi. When in range of this device, the smartphone should receive an ID and save it, after that, the smartphone should just inform if it is range or not. My question is what should I use in order to be possible to have dozens of active connections at the same time? I've heard about BLE (Bluetooth Low Energy), but I'm not sure if I can accomplish what I want with this. Any suggestions would be much appreciated.</p>
  <p>Thank you.</p>
