篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了蓝牙连接，原因码= 0x000e-Android相关的知识，希望对你有一定的参考价值。
我正在尝试创建一个连接/断开BLE设备的应用程序。我已经使用标准的android BT API创建了一个应用程序。这是我连接BLE设备的代码

[当我检查原因码0x000e时，它说这是因为BT_HCI_OP_PIN_CODE_NEG_REPLY。但是我不知道为什么会出现原因代码？
提前感谢！
Maulik
答案
我找到了上述问题的解决方案。
问题是我称他为“ createBond”方法，因为我希望将其配对。但是我没有配对的设备只是简单地连接而不配对，所以我删除了配对代码，直接调用了gatt.connect（）方法。
谢谢
以上是关于蓝牙连接，原因码= 0x000e-Android的主要内容，如果未能解决你的问题，请参考以下文章
