title: Pair Android Bluetooth without passkey to PC
body: <p>my issue is that I have a PC host to manage Bluetooth connections in a wide room, e.g. a shopping center. And I want that any customer who wants to pair to that host, which provides a service, do it automatically without asking for a passkey by the PC, since this will not be managed by anyone.</p>
  
  <p>My real application is a platform which manages this kind of connection and I want to pair BT devices to it, but not asking for any passkey at least from PC side.</p>
  
  <p>Thanks in advance.</p>
