Android Beacon Library在一台Android 4.4设备上运行良好,但在另一台Android设备上运行良好_app

智能手表(通用)列为蓝牙4.0功能
MTK6572芯片组
型号EC720(似乎有很多变种)
Android 4.4.2
内核：3.4.67 chendalin-Z87-HD3#1 2014年12月27日
内部版本号：H82D.SMARTWATCH.OC4.0.20141447
自定义版本：1419655453

我正在使用相同的Radius Networks标签信标测试相同的应用程序.在这个测试中,我在我的设备的近距离内有相同的4个信标.

设备1是Nexus 7(2013),我还没有更新到AndroID L,它运行4.4.4

Device 2是一款通用的智能手表,在MTK6572上运行androID 4.4.2.规格列出有蓝牙4.0

当我使用AndroID Beacon library运行我的测试应用程序时,Nexus报告信标,但智能手表没有.它似乎检测到它们,但我看到logcat中的条目如：D / BluetoothAdapter：onScanResult() – Device = E5：E0：20：CF：63：32 RSSI = -60.当BeaconParser未设置为读取正确类型的信标时,通常会显示这些消息,但在我的情况下,我很确定这不是问题,因为nexus看到的信标具有完全相同的代码.

对于2个设备看起来非常不同的日志输出,我开始怀疑手表的androID构建是否因为BLE支持被禁用或者具有不完整的堆栈.我已经仔细检查了蓝牙是否打开,并且还想注意该手表具有应用程序权限管理,我为应用程序请求的所有权限设置为“始终允许”.

添加更多特定日志条目以尝试显示信标检测中的差异：我删除了除一个信标之外的所有信息,我注意到工作设备正在通过UUID识别信标,而非工作设备则不是.但我在工作设备的日志中找不到对Device = E5：E0：20：CF：63：32的任何引用.

而在工作设备中,大多数信标的记录似乎来自该类…

回答DavID关于MAC地址的问题

以下代码：

beaconManager.setRangeNotifIEr(new RangeNotifIEr() {    @OverrIDe    public voID dIDRangeBeaconsInRegion(Collection<Beacon> beacons,Region region) {    System.out.println("------- dIDRangeBeacons!!!!");    iBeacons = beacons;    System.out.println("------ num:: " + iBeacons.size());    for(Beacon iBeacon : iBeacons) {        Log.i("Beacon","\n------------------------------------------------");        Log.d(TAG,"Mac address is: "+iBeacon.getBluetoothAddress());        Log.i("Beacon","\n------------------------------------------------");    }    }});

在工作Nexus 7上产生：

02-03 19:44:57.200    3192-3438/com.mapcushion.androID.mapcushionPingl I/System.out﹕ ------- dIDRangeBeacons!!!!02-03 19:44:57.200    3192-3438/com.mapcushion.androID.mapcushionPingl I/System.out﹕ ------ num:: 102-03 19:44:57.200    3192-3438/com.mapcushion.androID.mapcushionPingl I/Beacon﹕ ------------------------------------------------02-03 19:44:57.200    3192-3438/com.mapcushion.androID.mapcushionPingl D/RangingActivity﹕ Mac address is: E5:E0:20:CF:63:3202-03 19:44:57.200    3192-3438/com.mapcushion.androID.mapcushionPingl I/Beacon﹕ ------------------------------------------------

在智能手表上：

因此BeaconManager(或底层的androID API)没有将“设备”视为信标,但它确实用这条线识别具有相同MAC地址的信标：

02-03 19:40:46.486    2620-2633/com.mapcushion.androID.mapcushionPingl D/BluetoothDevice﹕ mAddress: E5:E0:20:CF:63:32

编辑3：

我决定退后一步,尝试使用AndroID蓝牙API直接查询信标.

基本上我只是想输出返回的字节,看看为什么没有识别信标.并且对于相同的信标,输出看起来完全不同,只有前两个字节具有智能手表所见的信标数据,而nexus 7具有30个字节的数据.

到目前为止,我尝试更改SCAN_TIME没有任何效果.手表收到的数据是否有迹象表明它无法读取数据包？

我使用了以下代码：

private static final long SCAN_TIME = 5000;    boolean mScanning = false;    private voID scanLeDevice(final boolean enable) {        Log.i(null,"InsIDe scanLeDevice");        Log.i(null,"scan time is: " + SCAN_TIME);        if (enable) {            // Stops scanning after a pre-defined scan period.            mHandler.postDelayed(new Runnable() {                @OverrIDe                public voID run() {                    mScanning = false;                    Log.i(null,"Calling stopLeScan");                    mBluetoothAdapter.stopLeScan(mLeScanCallback);                }            },SCAN_TIME);            mScanning = true;            Log.i(null,"Calling startLeScan");            mBluetoothAdapter.startLeScan(mLeScanCallback);        } else {            mScanning = false;            mBluetoothAdapter.stopLeScan(mLeScanCallback);        }    }    private BluetoothAdapter.LeScanCallback mLeScanCallback =        new BluetoothAdapter.LeScanCallback() {            @OverrIDe            public voID onLeScan(final BluetoothDevice device,int RSSi,final byte[] scanRecord) {                runOnUiThread(new Runnable() {                    @OverrIDe                    public voID run() {                        Log.i(null,"INSIDE ONLESCAN");                        //DO MY WORK                        Log.i(null,"scanned record: " + scanRecord.length);                        int startByte = 2;                        boolean patternFound = false;                        for(int i=0; i<scanRecord.length; i++) {                            Log.i(null,"byte " + i + ": " + scanRecord[i]);                        }                        while (startByte <= 5) {                            Log.i(null,"scanned record: " + scanRecord.length);                            Log.i(null,"IDentifIEr check: " + ((int) scanRecord[startByte + 2] & 0xff) + " == " + 0x02);                            Log.i(null,"Length of data : " + ((int) scanRecord[startByte + 3] & 0xff) + "==" + (0x15));                            //Log.i(null," iBeacon IDentifIEr: " + (scanRecord[startByte + 2] & 0xff));                            if (((int) scanRecord[startByte + 2] & 0xff) == 0x02 && //IDentifIEs an iBeacon                                    ((int) scanRecord[startByte + 3] & 0xff) == 0x15) { //IDentifIEs correct data length                                patternFound = true;                                break;                            }                            startByte++;                        }                        if (patternFound) {                            //Convert to hex String                            byte[] uuIDBytes = new byte[16];                            System.arraycopy(scanRecord,startByte+4,uuIDBytes,16);                            String hexString = bytesToHex(uuIDBytes);                            //Here is your UUID                            String uuID =  hexString.substring(0,8) + "-" +                                    hexString.substring(8,12) + "-" +                                    hexString.substring(12,16) + "-" +                                    hexString.substring(16,20) + "-" +                                    hexString.substring(20,32);                            //Here is your Major value                            int major = (scanRecord[startByte+20] & 0xff) * 0x100 + (scanRecord[startByte+21] & 0xff);                            //Here is your Minor value                            int minor = (scanRecord[startByte+22] & 0xff) * 0x100 + (scanRecord[startByte+23] & 0xff);                            System.out.println("-------------output------ : " + uuID + " maj: " + major + " min: " + minor );                        }                    }                });            }        };    }

这是输出：

解决方法由于您使用Nexus 7确认信标的Mac地址为E5：E0：20：CF：63：32,您会看到该手表的广告显示为：

0201000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

虽然Nexus 7将其读作一个非常不同的字节序列：

02011a0bff4c0009060102c0a801130000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

我必须得出结论,手表没有正确读取BLE制造商的广告 – 它在两个字节后截断它们.

问题可能是MTK6572 ROM,硬件或两者协同工作的方式.为了其他人,可能值得记录完整的手表配置.
