Question

我正在测试长寿/健壮性问题，需要调试偶尔的核心蓝牙错误，例如＃242。

Apple是否列出了每个核心蓝牙错误的含义？

通常，CoreBluetooth使用Bluetooth Core Spec V4.0 Vol 3 Part F Sec 3.4.1.1 Table 3.3 Error Codes中定义的标准错误代码。

                             Error

                                   has encountered an error that was unlikely, 
                                   and therefore could not be completed as

Application Error     0x80 – 0xFF  Application error code defined by a higher 
                                   layer specification.

请注意，iOS存在显示任意错误代码的某些问题。例如，如果您在一定时间内未能将请求作为外围应用程序回答，则返回的错误代码没有任何意义。

实际错误代码始终仅在打印到控制台的警告中可见。在任何情况下，NSError都没有提供我目前遇到的CoreBluetooth的任何详细信息。

Apple的文档包含CoreBluetooth Constants列表，其中包含您将从框架中收到的大多数错误代码。

我还开始Wikia site for CoreBluetooth收集有关人们遇到特定errors的情况的其他信息。

在哪里可以找到Core Bluetooth的Apple iOS错误列表？
