ibeacon

问题 I am trying to implement a mobile app (on iPhone) that just scans for beacons and displays a notification for each one. I am a noob with beacons/bluetooth. I implemented it using the universal beacon library (https://github.com/andijakl/universal-beacon) and i've attached my ios bluetooth implementation. my problem is that i receive about 12 beacon added events even though i only have two (I assume it is picking up all my other bluetooth devices). I also only receive the local name in the

问题 I am writing Android Application on finding and detecting IBeacons(These are BLE devices) and ranging them(depending on RSSI value) I use Sample code from https://developer.android.com/guide/topics/connectivity/bluetooth-le.html But this Code works different on my android devices (Samsung Galaxy S3 and LG G3). On my S3 the "onLeScan" callback rises many times in loop (about 5 per second) and give me different RSSI values every time depending on the range. But on my LG G3 the "onLeScan"

问题 For StartMonitoring iBeacon my code is -(void)startMonitoringForRegionWithUUID:(NSString*)UUID { CLBeaconRegion *beaconRegion= [[CLBeaconRegion alloc] initWithProximityUUID:[[NSUUID alloc] initWithUUIDString:UUID] identifier:UUID]; beaconRegion.notifyOnEntry = YES; beaconRegion.notifyOnExit = YES; beaconRegion.notifyEntryStateOnDisplay=YES; //[self stopMonitoringForRegionWithUUID:UUID]; [self.locationManager startUpdatingLocation]; [self.locationManager startMonitoringForRegion:beaconRegion];

问题 I'm getting this crash in Apple's CoreLocation thread in our production app. I am not able to reproduce it in my testing also its hard to figure out as its inside CoreLocation. At the moment its happening with few percentage of population but I can see its getting bigger. Crashed: com.apple.CoreLocation.ConnectionClient.0x16fcb870.events 0 CoreLocation 0x2aa2db54 CLClientCreateIso6709Notation + 53675 1 CoreLocation 0x2aa2dc7b CLClientCreateIso6709Notation + 53970 2 CoreLocation 0x2aa2de03

问题 I managed to create an app which turns the phone into a beacon emitter. It works fine on xcode (Swift) and phonegap . The next step for me is making it work in the background as a beacon (I'm developing for iOS 10). I found similar questions to this online but all of them were out of date ie old ios , objective-C and outdate plug-ins would really appreciate it if someone can provide me with a working example or guide me on what to change in my code for both an xcode s(wift) and phonegap Xcode

问题 My code has now reached checkpoint 1 and 2. However, it is only detecting the beacon once. I want it to keep receiving the location of the beacon (distance) every five seconds. How can I implement this? Thanks again public class RangingService extends Service implements BeaconConsumer { private BeaconManager beaconManager = BeaconManager.getInstanceForApplication(this); Handler handler; String b = ""; @Override public IBinder onBind(Intent arg0) { return null; } @Override public void onStart

问题 I want to set the current time as the major and minor values of a beacon. Lets suppose this is the current time 1465398279009 . I want 9827 to be the value of the major and 9009 the value of the minor. I use a java code to call the shell script. this is my java code Long millis = System.currentTimeMillis(); String time=Long.toString(millis); // String major1=time.substring(...); String major1="99"; String major2="99"; String minor1="99"; String minor2="99"; ProcessBuilder pb2=new

问题 In a Fragment I have a list of items construct with RecyclerView (adapter and viewholder). Each item of the list is linked with a estimote beacon. So i want to highlight the item view (setAlpha or add a imageView) when the beacon is detected. The beacon detection is in the fragment file : beaconManager.setRangingListener(new BeaconManager.RangingListener() { @Override public void onBeaconsDiscovered(Region region, List<Beacon> list) { if (!list.isEmpty()) { Beacon nearestBeacon = list.get(0);

问题 First question is better is Estimote SDK or CoreLocation framework? I have app which is finding the beacons but now i must made an app which will find beacons when application is in background or even is terminated. 回答1: Setting up background detection is pretty automatic in iOS so long as you do it in your AppDelegate and receive callbacks in that class: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { _locationManager = [

问题 I'm trying to build an ionic2 application. I want to send notifications to users when ibeacon is detected. It worked with this code in angularjs. How can I do this with angular2 like the code below? <div class="row" ng-controller="Example1Controller" ng-init="add()"> 回答1: You should call it inside the ngOnInit export class yourComponents implements OnInit { ngOnInit() { this.add(); } } 回答2: <div class="row" ng-controller="Example1Controller" ng-init="add()"> Basically in above code ng
