startScan() only lists device once

[rms95]

I am trying to use evothings cordova-ble for scanning beacons which use advertising packets as periodic broadcasts.

At this point I only get a scan result once per device, not every advertisement packet, but I need it every packet.
Some other (non-Cordova) libraries by Evothings do allow this via a parameter for the startscan function. Is it possible to do this at the Cordova platform as well?
(I am talking about allowDuplicates in https://evothings.com/doc/lib-doc/evothings.easyble.html#.ScanOptions)

My code:

evothings.ble.startScan(
	function(device) {
		
	},
	function(errorCode) {
		
	}, {
		allowDuplicates: true
	}
);

I'm using Android 6.0.1 with custom Bluetooth beacons.
