Unable to range and broadcast on Samsung Android 12

[wieger]

Hi, I have build an app to scan for beacons using this package. It all works flawlessly on iOS devices but I cannot get it to work on my Android device, a samsung S10 running android 12. I hope that someone which has managed to get it working can help me debug it, or point me towards a step I missed during the setup. To debug it I am now running the example code provided in the repository At first I was missing the proper permissions but I think I have that sorted, combining some previous posts on this forum.

I have the following permissions in main/AndroidManifest.xml

   <uses-permission android:name="android.permission.INTERNET" />
    <!--Before Android 12 (but still needed location, even if not requested)-->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    <uses-permission android:name="android.permission.BLUETOOTH" tools:remove="android:maxSdkVersion" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" android:maxSdkVersion="30" />

    <uses-permission android:name="android.permission.BLUETOOTH_SCAN" android:usesPermissionFlags="neverForLocation" />
    <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADVERTISE" />

I request the required permissions with the following code, and all statuses resolve to granted

import 'package:permission_handler/permission_handler.dart';  //permission_handler: ^10.2.0

    PermissionStatus scan = await Permission.bluetoothScan.request();
    PermissionStatus connect = await Permission.bluetoothConnect.request();
    PermissionStatus bt = await Permission.bluetooth.request();
    PermissionStatus advertise = await Permission.bluetoothAdvertise.request();

I listen for beacons using: _streamRanging = flutterBeacon.ranging(regions).listen((RangingResult result) { print(result);

this does print a result but it contains no beacons:

I/flutter (27838): {"region":{"identifier":"BeaconType2","proximityUUID":"6a84c716-0f2a-1ce9-f210-6a63bd873dd9"},"beacons":[]}
I/flutter (27838): {"region":{"identifier":"Cubeacon","proximityUUID":"cb10023f-a318-3394-4199-a8730c7c1aec"},"beacons":[]}
I/flutter (27838): {"region":{"identifier":"MyRegion","proximityUUID":"xxxx-x-x-xxxx"},"beacons":[]}

Any help is greatly appreciated, thanks

@wieger did you find a solution? I'm facing the same issue. Thank you in advance

Unfortunately not, it must be something silly in the configuration. but after spending too much time on it I finally gave up on it. If you do get it to work please post it here!

Regards Wieger
