I'm running into a hardware issue where connecting multiple bluetooth LE devices causes a bottleneck and I can not connect more than 5 or 6 without issues. I have external USB Bluetooth 4.0 (LE) dongles that I can connect to my Mac. I know that the IOS Simulator requires that you have an external USB Dongle to use Bluetooth in the simulator. Is there a way to attach to additional dongles programmatically and reliably.
