altbeacon

问题 Can we detect beacons in app background(Both iOS and Android). I see Eddystone beacon have some problem with background of iOS. How can solve that ? 回答1: iOS does allow background detection of service advertisements like Eddystone, but Eddystone detection times can be slower than iBeacon . The reason iBeacon detections are faster is because Apple has optimized it with hardware filters . Hardware filter slots in the bluetooth chip are activated when you monitor an iBeacon region on iOS. This

问题 I am working with kontakt.io Bluetooth eddystone UID beacons and an android application using the alt-beacon library (running on a Samsung Galaxy S5, although I doubt that is relevant). I've done a bunch of trials under different conditions and am working towards determining the feasibility of high-accuracy tracking via trilateration of multiple beacon signals. On multiple occasions I have noticed a regular oscillation of the beacon's RSSI being detected by the android device. Here is one of

问题 Hi i have created app using altbeacon reference app. And i want to call didEnterRegion using bootstrap notifier when app sees beacon in background. But i dont want it to scan background every 5 minutes, i want my app react to new beacon immediately. Is there some way to do this ? My Code : private static final String TAG = ".Application"; private final Identifier uuid = Identifier.parse("A1B2C3D4-AAAA-48D2-B060-D0C0D0C0D0C0"); private RegionBootstrap regionBootstrap; @Override public void

问题 I stuck implementing simple Beacon monitor with AltBeacon library using its examples. In short: I took its reference application, downloaded and integrated its latest build and run app on my Samsung Galaxy S2 with CM (Android 4.4.4). I see that onBeaconServiceConnect callback never called, though bindService is called. I believe onBeaconServiceConnect should be called in order application to work correctly. I've tried to set beaconManager.debug = true; but it didn't show me any new logs

问题 I have some problems in my app. I have that after I disable the regionBootstrap and close the app through System.exit(0), my app after some minutes (usually 3-4 minutes) restarts itself. This are the Logcat lines that I found everytime my app restarts: 2018-11-24 14:54:34.883 897-1339/?

问题 I have an Android Application that among other things monitor beacons using the AltBeacon library. My problem is that, from my understanding, to have a class monitoring beacons you must make this class extend Application. But I already have a class extending Application. Now I cant make my other class not extend Application and I cant make my " beaconClass " extend this class. My only option is to find a way to use the AltBeacon library without extending Application. So I would like to know

问题 I am using Android with the AltBeacon library. I am starting to develop a BLE app which should tell me when a beacon is entering and when it is exiting a range inside a region so I can start an action. I could detect when a beacon is entering a region and determine his range. Therefore I used the didRangeBeaconsInRegion Method. My problem is now how to detect that a beacon has left/exited that range in the region? I couldn't find anything in the lib to do so. How can I achieve this? 回答1: The

问题 BluetoothCrashResolver detects a crash on app launch the sequence of flow is as follows: 1.the device's bluetooth is off initially 2.the app is launched 3.the app first checks whether bluetooth is on 4.if not ON,app displays a popup to enable bluetooth 5.User allows bluetooth to be switched on 6.bluetoothresolver says "crash detected" as lastBluetoothTurningOnTime=01/01/1970; lastBluetoothOffTime=01/01‌​/1970; so the if statement inside "case BluetoothAdapter.STATE_ON" fails. Let me know if

问题 When multiple beacons are detected in the regions, how can I find that which one is the newest detected one? Also in beacon exist how can I know that specific beacon has left the region. 回答1: The typical way to solve this is to combine beacon monitoring and beacon ranging . You use beacon ranging to read the individual identifiers, and keep a map of what beacons have been seen before like this: private HashSet<Beacon> beaconsSeen = new HashSet<Beacon>(); @Override public void

问题 I am currently exploring retail advertising options. I am interested in AltBeacon as it is an open standard. I have a basic question, if someone can answer How can I programmatically set UUID, major ID, minor ID, advertisements frequency, broadcasting power and RSSI at 1m in Altbeacon format on both (i) IOS devices and (ii) Android devices? As Locate App is taking these values as variables from users, I guess they are inputting these values programmatically?! 回答1: If you wan to know how to do
