更新：我尝试了一种更直接的方法（参见下面的编辑 3），这会导致手表上的信标缺少有趣的数据。
非工作设备的详细信息。Smartwatch（通用）列为支持蓝牙 4.0 的 MTK6572 芯片组型号 EC720（似乎有很多变体）Android 4.4.2 内核：3.4.67 chendalin-Z87-HD3 #1 Dec 27th 2014 内部版本号：H82D.SMARTWATCH.OC4.0.20141447自定义构建版本：1419655453
我正在使用相同的 Radius Networks Tag 信标测试相同的应用程序。在这个测试中，我的设备附近有相同的 4 个信标。
设备 1 是我尚未更新到 Android L 的 Nexus 7 (2013)，它正在运行 4.4.4
设备 2 是一款通用智能手表，在 MTK6572 上运行 android 4.4.2。规格将其列为具有蓝牙 4.0
当我使用 Android 信标库运行我的测试应用程序时，Nexus 会报告信标，但智能手表不会。然而，它似乎检测到它们，我在 logcat 中看到条目，例如：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，似乎这些消息通常会显示，但在我的情况下，我很确定这不是问题，因为 nexus 看到具有完全相同代码的信标。
两个设备的日志输出看起来非常不同，我开始怀疑手表的 android 版本是否以某种方式禁用了 BLE 支持或堆栈不完整。我已经仔细检查了蓝牙是否已打开，并且还想注意手表具有应用程序权限管理，对于应用程序请求的所有权限，我将其设置为“始终允许”。

添加更具体的日志条目以尝试显示信标检测的差异：我删除了所有信标，但只有一个信标，我注意到工作设备通过 UUID 识别信标，非工作设备不是。但是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，信标的大部分日志记录似乎来自该类......

回应大卫关于 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------------------------------------------------");
}
}
});
在工作的 Nexus 7 上产生：

因此，BeaconManager（或底层 android API）没有将 ble 设备“视为”为信标，但它确实使用以下行标识了具有相同 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，看看为什么不能识别信标。对于同一个信标，输出看起来完全不同，只有前两个字节有智能手表看到的信标数据，而 nexus 7 有 30 个字节的数据。
我尝试更改 SCAN_TIME 到目前为止没有任何效果。手表接收不到数据是否表明它无法读取ble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, 0, 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：
