Moto G蓝牙低功耗(BLE)配对问题

Question

我已经创建了使用血糖仪的样本应用程序.示例应用程序具有配对,连接和从仪表等获取数据的选项.我正在使用Google BLE API来实现此目的.

问题:

1. 几乎70%的时间,Moto G从未通过BLE扫描发现血糖仪.
2. 如果它发现并且示例应用程序试图配对,则配对失败.
3. 非常少数样品应用成功与血糖仪配对.之后,如果应用程序尝试从血糖仪中获取数据,则仪表将从Moto G中取消配对.

当我们尝试将血糖仪与标准蓝牙配对程序配对时,观察到相同的问题.我们尝试了4-5种不同的血糖仪,但问题仍然存在.示例应用程序适用于三星Galaxy S5,HTC ONE,Samsung Note II和III,LG G2等不同的其他设备.

Moto G中是否有任何已知的BLE问题？如何解决上述问题？

建立:

•Moto G - Android版本4.4.2

•Eclipse Indigo.

我给出了我的示例应用程序的日志以供参考.
