startScanning() only works in test.js #72

I have my doorbeacon.js file in the same directory as my cloned node-bleacon. When I run test.js, it finds my beacons. When I copy the exact contents of tets.js into my node js file, it skips right over it. I believe it is actually running the service because it renders BLE useless unless I reboot. Not even HCI resets or up/down commands fixes it. I ran a debug and here is what I have (when it gets to "onoff mode" that's where my js code continues):

I have been able to get it to work in my node js file. Turns out the process runs and then enters another loop where it waits for my input and that was blocking it from reentering the bleacon.on('discover'...) event. So now my question is more of a general coding question... How do I keep this continuous while at the same time running another process?

@ethicaldesign you should make your other code non-blocking, so it doesn't block the Node.js event loop and block bleacon/noble.
