问题 It is designed to scan every 4 seconds. However, beacons may not be detected from the start to the stop of scanning. After that, the beacon is detected after stopping the scan. The problem occurs at the following dates and times in the log. 08:54:20.807 D/CycledLeScanner(21211): Scan started 08:54:21.906 D/CycledLeScanner(21211): Done with scan cycle 08:54:22.336 D/Cycled LeScanner(21211): stopping bluetooth le scan 08:54:23.638 D/CycledLeScannerForLollipop(21211): got record And after this

问题 I can see that the Android Bacon Library features two algorithms for measuring distance: the running average filter and the ARMA filter. How are these related to the library's implementation (apart from using the filter's formula)? Where can I find some background information about these that explains the theory behind it? Are there any known alternative algorithms that can be studied and tried out for measuring the distance? 回答1: There are two basic steps to giving a distance estimate on BLE

问题 Is it possible to transmit and receive beacon signals at the same time using an android device acting as a beacon? 回答1: Yes, on Android 5+ devices that support beacon transmission (see the list here), you can both send and receive beacon transmissions simultaneously. You can see a demonstration of this using the Android Locate app. Simply turn on a transmitter, then switch to locating beacons. If you do this on two Android phones at the same time, they will both see eachother's transmission.

问题 My app using Altbeacon library for beacon scanning. my code working well to api level 24(android 7) but doesn't not working on oreo(8.0.0) at first, my gradle setting compileSdkVersion and targetSdkVersion is 26, i thought it was because of this. so, i reference this**https://developer.android.com/about/versions/oreo/background.html#services**, fix my gradle setting(compileSdkVersion 25, targetSdkVersion 25). and install this app on device (apilevel 24, 26) on 24 level device working well,

问题 I have the estimate beacon and I can change uuid from their iOS app but from what i read beacon use BLE tec. and it made to send only advertisement data so how does it receive the new configuration. thanks 回答1: It is true that iBeacons only advertise data, however vendors, such as Estimote, can support additional BLE functionality to allow functionality such as configuration. This is outside of the iBeacon specification and so each vendor will have their own services and chracteristics for

问题 Overview of application: 1. Signup for Radius Developer's proximity kit and create Fences. 2. Get JSON response from PKKitURL in ProximityKit.properties file downloaded from website. 3. Parse JSON response to get lat and long. Get user's location and check for proximity. Currently, i have done signing up, creating fences, downloading .properties file and all other basic things needed to integrate the ProximityKit's SDK. Now I want to get the JSON response from the URL that's present in
