Does anybody know if there is a way (in Erel's chat example) to search only for devices that have the same app (Erel's chat example) installed in it, and not all devices nearby that have bluetooth activated.
All nearby discoverable BT devices will be discovered. If there aren't too many devices then you can try to connect to all of them. You can use a unique UDID so it will not connect to other apps that are listening for connections on the default UDID.
