With physical web integration in new google chrome browser (still in beta), its possible to detect beacons that emit Eddystone Url frames.

I downloaded Chrome Beta, enabled physical web going to chrome://flags, gave the app access to location services, gave runtime permission for using location (I am using Marshmallow), but the browser still wasn't able to detect a beacon nearby. I tried using physical web app as well as Opera Labs version and both are able to detect the same beacon.
I am using RadBeacon USB by Radius Networks.
What am I missing here?
My first guess is that your URL is an HTTP URL. You have to be pointing to an HTTPS URL for Chrome to display it.
Chrome 50 will have a physical-web diagnostics page to show issues like this.
