eddystone

问题 I'm trying to make an hybrid app by which phone will act as beacon, which mean it should transmit both an iBeacon and an Eddystone. Is there any cordova plugin available if not can anyone please suggest how can I make one. 回答1: This Cordova plugin supports detection on both iOS and Android: https://github.com/petermetz/cordova-plugin-ibeacon It only supports transmission on iOS, but the underlying native Android Beacon Library it uses supports transmission: http://altbeacon.github.io/android

问题 I'm trying to build an access control system using BLE beacons and a web server. A mobile phone will transmit a beacon signal near the gate and the beacon will be forwarded to the server to decide whether this person should pass. The problem is transmitting a beacon without encryption is not safe, i need to encrypt the beacons. The question is: is there an API for web applications to resolve the Eddystone EID encrypted beacon without using google web service? Another question: is the

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 I have created an android application to scan for BLE using Bluetooth LEscanner. Now that I need my app to identify if a beacon belongs to iBeacon or Eddystone. So far, I'm successful in determining UUID,MajorId,MinorId of ibeacon by parsing the AD frame. 回答1: It's relatively easy to read the bytes of the advertisements if you know the byte offsets of all the fields. Two code snippets below show you how you can parse these out. The first shows how you can do this in your own onLeScan callback

问题 I'll describe my setup : I have made an android application that simulates Eddystone beacon. I was able to detect the Eddystone beacon on my phone using Beacon Toy app from PlayStore. But the thing is , from the last time I checked , the MAC ID displayed has changed. I can identify its the same beacon because of the namespace and instance id being the same but under different MacID. Could someone suggest what is happening here ? I was under the impression that MacID stays constant. 回答1: Yes,

问题 I have got SENSORO beacon which I have configured using congif tool from Sensoro. Then I have created a project for beacon(Google API). Then I have registered the beacon using Beacon Tool from google, it got registered. But I am unable to see my beacon in Google Beacon Platform. I waited for almost 20 hrs but still not appearing. BTW what is difference between Eddystone and Eddystone URL, because for a single beacon I was getting Eddystone(This got registered) and Eddystone URL(Still

问题 I am using altBeacon library for beacon detection. After checking out the sample codes on Beacon detection, they always implement the Interface BootstrapNotifier on the Application class instead of Activity , which is used for detecting beacons in the background. However I have noticed that beacon detection in the background stops when BootstrapNotifier is implemented on Activity . I don't want my app to detect beacons as soon as it is launched hence I have not implemented BootStrapNotifier

问题 I am asking a follow up question to my previously asked question -> http://stackoverflow.com/questions/33607410/background-monitoring-of-eddystone-beacon-using-altbeacon-library-on-android-pla/33613116?noredirect=1#comment55139316_33613116. Where i was able to successfully detect beacons both in the foreground and background until I found out that the same code was unable to detect the beacon when i try to run it on nexus 5 device running android 6.0. Can anyone provide a explanation to why

问题 I introduced “ Factory Pattern ” in my beacon scanning module. I referred http://crosbymichael.com/objective-c-design-patterns-factory.html In my Factory class, 2 modes of beacons are switched between Interface classes “ PCGoogleBeacon.h ” and “ PCAppleBeacon.h ”. //Header file of Factory typedef enum beaconMode { iBeacon, Eddystone } BeaconMode; @interface PCBeaconFinder : NSObject +(id) searchForBeaconMode:(BeaconMode) beaconMode; @end //Implementation of Factory +(id) searchForBeaconMode:
