[解決済み] Android Bluetooth Low Energy - ScanFiltersの使用方法

2022-02-26 03:31:04

質問

現在、Bluetooth Low Energyのスキャン用Androidアプリを制作しています。Android 5.0では、ScanFiltersのオプションが導入されました。一般的に動作していますが、フィルタの数が制限されているようです（？）

13種類以上のフィルターを使用すると、BLEデバイスが見つからなくなり、何も見つからずにバックグラウンドで継続しているにもかかわらず、アプリが停止した旨の通知が表示されます。警告やエラーメッセージは表示されません。使用するフィルタを13個より少なくすると、すべてがうまく機能します。また、フィルタリングに使用するアドレスは、問題の原因にはなりません。どうやら最大数になるようです...。

コードです。スキャンは独自のスレッドで実行されます。

[...]
BluetoothLeScanner myScanner = myBluetoothAdapter.getBluetoothLeScanner();
ScanSettings settings = new ScanSettings.Builder().setScanMode(ScanSettings.SCAN_MODE_LOW_LATENCY).build();


//The list for the filters
filters = new ArrayList<>(); 

//mac adresses of ble devices
String[] filterlist = {
                    "D4:B4:C8:7E:D1:35",
                    "C8:86:3A:91:0C:0C",
                    "FD:49:FD:36:04:B4",
                    "E9:91:4A:42:AC:3B",
                    //... some 20 more addresses
};

//adding the mac adresses to the filters list
for (int i=0; i< filterlist.length ; i++) {
    ScanFilter filter = new ScanFilter.Builder().setDeviceAddress(filterlist[i]).build();
    filters.add(filter);
    Log.v("Filter: "," "+ filters.get(i).getDeviceAddress());
}



[...]
while (scanning) {
    final ScanCallback callback = new ScanCallback() {
        @Override
        public void onScanResult(int callbackType, ScanResult result) {
           Log.v("Callback","in the callback");
    }
    @Override
    public void onScanFailed(int errorCode) {
        super.onScanFailed(errorCode);
        Log.v("ScanTask", "Some error occurred");
    });

    [...]

    //starting the scan with the filters
    myScanner.startScan(filters, settings, callback);

    //creating some delay and then end the scan
    Thread.sleep(myScanTime);
    myScanner.stopScan(callback);

    [...]
}

コード内は問題ないようです。しかし、なぜフィルタの最大数に制限があるのでしょうか？どなたか正しい方向に導いてくださるか、回避策をご存じですか？

UPDATEしてください。 Logcatでappフィルターを削除すると、エラーメッセージが表示されるので、参考になるかもしれません。これはLogcatです。

フィルタの使用可能スペースに変数があり、フィルタの追加数に関係なく常に15に設定されているようです(?)

onScanFilterParamsConfigured() - clientIf=6, status=0, action=0, availableSpace=15

フィルタを1つ追加するごとに1つずつ減っていき、3つ以下になるとNoSuchElementExceptionが発生します。

どのように解決するのですか？

この問題は、明らかにAndroid 5.0のバグです。新しいバージョンのAndroid（5.0.2でテスト）では、バグが修正され、この問題は発生しなくなりました。ありがとうございました。
