我有个问题。我的 android 代码与 iOS 蓝牙广告不兼容。我在苹果文档上读到,广告是在 iOS 设备之间进行的。

但是我认为如果iOS可以读取它,那么android为什么不可以呢?android 设备是否接收到字节数组中的 uuid?我该如何解析这些?可能吗?

当 iOS 使用此代码时,如何在 Android 设备上读取广告数据:

CBPeripheralManager *manager = [[CBPeripheralManager alloc] initWithDelegate:self queue:nil];
NSArray *uuids = @[[CBUUID UUIDWithString:@"128bit uuudid"],
                   [CBUUID UUIDWithString:@"other 128bit uuudid"],
                   [CBUUID UUIDWithString:@"128bit uuudid"],
                   ....];

NSDictionary *data = @[CBAdvertisementDataLocalNameKey: @"My name",
                       CBAdvertisementDataServiceUUIDsKey: uuids]; 
[manager startAdvertising:data];

我尝试在 Android 上扫描 UUID,但它只读取第一个 uuid。我如何阅读其他人?

我使用此代码在 Android 上解析 UUID,但它不起作用。

public void onLeScan(BluetoothDevice device, int rssi, byte[] scanRecord) {
     ParcelUuid[] uuids = device.getUuids();

     List<UUID> ud = parseUuids(scanRecord);
     if (ud != null) {
          for (UUID u : ud) {
               Timber.v("UUUUID: %s", u);
          }
     }
}

private static List<UUID> parseUuids(byte[] advertisedData) {
        List<UUID> uuids = new ArrayList<UUID>();

    ByteBuffer buffer = ByteBuffer.wrap(advertisedData).order(ByteOrder.LITTLE_ENDIAN);
    while (buffer.remaining() > 2) {
        byte length = buffer.get();
        if (length == 0) break;

        byte type = buffer.get();
        switch (type) {
            case 0x02: // Partial list of 16-bit UUIDs
            case 0x03: // Complete list of 16-bit UUIDs
                while (length >= 2) {
                    uuids.add(UUID.fromString(String.format(
                            "%08x-0000-1000-8000-00805f9b34fb", buffer.getShort())));
                    length -= 2;
                }
                break;

            case 0x06: // Partial list of 128-bit UUIDs
            case 0x07: // Complete list of 128-bit UUIDs
            case 0x15:
                while (length >= 16) {
                    long lsb = buffer.getLong();
                    long msb = buffer.getLong();
                    uuids.add(new UUID(msb, lsb));
                    length -= 16;
                }
                break;

            default:
                buffer.position(buffer.position() + length - 1);
                break;
        }
    }

    return uuids;
}
