我的闪动的Nexus 5至Android 5.0 preVIEW释放锤头lpx13d后，OS报告说，它不再支持蓝牙LE广告。如果调用：

After flashing my Nexus 5 to the Android 5.0 preview release hammerhead-lpx13d, the OS reports that it no longer supports Bluetooth LE advertising. If you call:

((BluetoothManager) this.getSystemService(Context.BLUETOOTH_SERVICE))
    .getAdapter().getBluetoothLeAdvertiser()

总是返回null。此外，新的方法：

always returns null. In addition, the new method:

((BluetoothManager) this.getSystemService(Context.BLUETOOTH_SERVICE))
    .getAdapter().isMultipleAdvertisementSupported()

总是返回false

always returns false

用于返回一个有效的对象上的第一款Android大号preVIEW发布了Nexus 5在6月份的第一个方法。它不再存在，闪烁的最新更新之后。

The first method used to return a valid object on the first Android L preview release for the Nexus 5 back in June. It no longer does, after flashing the latest update.

有谁看到这样呢？

推荐答案

不幸的是，从谷歌官方的回答是否，Nexus的5不再支持广告。

Unfortunately, the official answer from Google is no, the Nexus 5 no longer supports advertising.

我们在Android的5.0棒棒堂推出BLE外设模式。 Nexus的6和   的Nexus 9是支持BLE前两个生产的Nexus设备   外设模式。由于硬件芯片的依赖，老年人的Nexus   设备（4/5/7）将不会对棒棒糖访问该功能。

We introduced BLE peripheral mode in Android 5.0 Lollipop. Nexus 6 and Nexus 9 are the first two production Nexus devices that support BLE peripheral mode. Due to hardware chipset dependency, older Nexus devices (4/5/7) will not have access to the feature on Lollipop.

这是说，我已经证实，广告支持的的Nexus平板电脑9。看到这里的细节：http://developer.radiusnetworks.com/2014/11/18/beacon-transmission-with-android-5.html

That said, I have confirmed that advertising is supported by the Nexus 9 tablet. See here for details: http://developer.radiusnetworks.com/2014/11/18/beacon-transmission-with-android-5.html
