altbeacon

问题 I don't know where is the problem with my code, I'm trying to detect beacon using https://altbeacon.github.io/android-beacon-library sorry for bad English and I'm new in mobile application development. AndroidManifiets.xml <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.isleem.hospital"> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.BLUETOOTH"/> <uses

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 altbeacon on Android 10 has simply stopped working. Are there any changes required especially to go to Android 10? I have added the following permissions to my AndroidManifest.xml <uses-permission android:name=\"android.permission.BLUETOOTH_ADMIN\"/> <uses-permission android:name=\"android.permission.BLUETOOTH\"/> <uses-permission android:name=\"android.permission.ACCESS_FINE_LOCATION\"/> <uses-permission android:name=\"android.permission.ACCESS_BACKGROUND_LOCATION\"/> <uses-permission

问题 I'm currently building an app that turns my device into a Beacon while simultaneously scanning for other Beacons. I've currently implemented 2 packages: flutter_beacon: https://pub.dev/packages/flutter_beacon beacon_broadcast: https://pub.dev/packages/beacon_broadcast Everything is working as intended except that I'm broadcasting an AltBeacon and scanning for iBeacon, so my app can't recognize the signal I'm broadcasting. Is there a package that either broadcasts iBeacon or monitors AltBeacon
