How can I detect 4 ibeacon using ionic in sme area

Hi, recently I am working a project using ionic 2 to detect each ibeacon in those 4 zone in the exhibition. Find that the native function ionic 2 can detect ibeacon, but how can i register 4 BeaconRegion in one application ? many thx !

We have used below code to get data from api calls and applying those beacons details to ibeacons. Try this one.

	this.appService.getBeacons()
			.subscribe(beacons => {
				console.log(beacons);
				var i=0;
				for(i=0;i<beacons.length;i++){
					// setup a beacon region – CHANGE THIS TO YOUR OWN UUID
					this.region = this.IBeacon.BeaconRegion(beacons[i].beaconDetailes.beaconId,beacons[i].beaconDetailes.uuid);
					this.region.NotifyEntryStateOnDisplay = true;
					this.region.NotifyOnEntry = true;
					this.region.NotifyOnExit = true;

					// start ranging
					this.IBeacon.startMonitoringForRegion(this.region)
					.then(
						() => {
							resolve(true);
							console.log("monitor for region");
						},
						error => {

							resolve(false);
						}
						);


					this.IBeacon.startRangingBeaconsInRegion(this.region)
					.then(
						() => {
							resolve(true);
						},
						error => {

							resolve(false);
						}
						);
				}
			}
			);
