Altbeacon 库无法找到/跟踪设备附近的传输信标.



我正在使用altbeacon库进行接触者追踪。但是当设备靠近我的其他扫描手机时，我无法找到/跟踪我的设备。我基本上有两部手机， 一部用于扫描，另一部用作信标发射器.我能够从我的电话号码 2 作为信标传输.我也在定位信标应用程序中进行了测试.它展示了我的手机。但是当我在电话号码 1 上进行测试时，它不起作用。即使我的didDetermineStateForRegion和onBeaconServiceConnect被调用，我也无法在任何日志上看到任何信标.

以下是我的应用程序类：

谁能告诉我我做错了什么，或者是否缺少一些步骤。我尝试在stackoverflow上查看其他答案，但这是唯一一个在所有答案中到处都能看到新类和接口的库。太多的混乱。

附言

我正在尝试制作接触者追踪应用程序。任何其他图书馆或您可以推荐的东西也将不胜感激。

尝试在测试中倒车手机 1 和 2。 如果您使用BeaconScope进行扫描，它可以看到两部手机的传输1和2吗？ 如果您使用 BeaconScope 进行传输， 手机 1 或 2 上的应用能否看到信标传输？

如果您在一部或两部手机上无法检测到信标范围，请检查应用权限以确认已向应用授予位置权限。转到"设置"-">应用程序"-">您的应用程序"，然后检查授予的权限。

还要检查电话上是否全局启用了位置，以及蓝牙是否已打开。
