Android 21 API 中的 BLE 广告模式

Question

我正在使用 Moto G 2013 和 Nexus 5，需要将它们用作 BLE（低功耗蓝牙）广告商。 Android API 21 添加了此功能，并且两个设备都是运行 Android 5 Lollipop。

事实是，我相信硬件支持 BLE 广告，但我已经阅读过，似乎 Google 在 Nexus 5 中放弃了对 BLE 广告的支持，但我找不到关于 Moto 的任何信息G.

应该调用 this 方法来检查是否支持 BLE 广告，我是这样做的：

    BluetoothManager btManager = (BluetoothManager) getSystemService(BLUETOOTH_SERVICE);
    BluetoothAdapter btAdapter = btManager.getAdapter();

     if(btAdapter.isMultipleAdvertisementSupported()){
            //Do Stuff
        }
        else{
            //Do other stuff
        }

在 Moto G 和 Nexus 5 中，该方法 returns 错误。

有没有人有办法解决这个问题（或额外信息）？

关闭此更新：

这仅适用于具有 SDK21 的两种设备：Nexus 6 和 Nexus 9。其他设备不work/weren不支持。

我最终使用了 Nexus 9。

来自here（原link已死）：

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.
