Iphone iOS CoreBluetooth/iBeacon：同时发布iBeacon和外围服务

我正在为iOS编写一个应用程序，它要求应用程序同时发布iOS iBeacon和外围服务。有必要宣传服务，而不是简单地在外围设备上发现服务，因为用例要求在被iOS唤醒后（但仍在后台）连接到外围设备，因为靠近iBeacon。在Central上后台运行的应用程序只能通过可用服务发现外围设备，而不能发现所有外围设备[]；我的代码既可以宣传服务，也可以宣传iBeacon，但我还不知道如何同时做到这两个方面。有可能iBeacon使用了38字节可用空间中的21字节，而没有足够的空间来宣传信标和服务

这个工程（灯塔）：

本工程（服务）：

将两者相加，试图同时为这两项服务做广告是行不通的。它只宣传信标，不宣传服务：

self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uuid 
    major:1 
    minor:1 
    identifier:@"bentboolean"];
NSMutableDictionary *dict = [[self.beaconRegion peripheralDataWithMeasuredPower:nil] mutableCopy];  
[dict setValue:@[serviceUUID] forKey:CBAdvertisementDataServiceUUIDsKey];  
[self.peripheralManager startAdvertising:dict ];

谢谢你看

我可以使用单独的CLLocationManager和CLBeaconRegion分别为接收器和信标执行此操作：

这里唯一的限制是设备无法检测自身。

在我的实践中，iBeacon&BLE服务不能同时发布

如果播发与iBeacon混合，则BLE服务不能在前台播发。 iBeacon无法在后台播发

iBeacon&BLE服务可以一个接一个地播发，例如iBeacon播发0.5秒，然后 BLE服务广告30.0秒

希望这会有帮助

嗨，你解决过这个问题吗？我不认为这是可能的，因为蓝牙的容量…另一个有趣的观察我看到：即使另一个应用程序广告为iBeacon，你的应用程序无法检测到它。更重要的是，如果存在一个外部iBeacon来宣传相同的标识符，那么您的应用程序仍然无法检测到它。换句话说，公布iBeacon ID集会阻止对同一ID集的任何检测。不过，当将设备用作iBeacon时，如果您想将其用于此目的，自动为设备生成唯一的UUID（如果需要，甚至在启动时）非常简单。对我来说，最大的限制因素是1）用作iBeacon的设备根本不会在后台播放，2）应用程序不能在后台为单个iBeacon设置范围，除非在OnNet和onLeave事件中被唤醒，这些事件只有在进入或离开UUID区域时才会触发。@d2burke您提到，用作iBeacon的设备根本不会在后台广播。你知道即使应用程序使用蓝牙外围设备背景模式，情况是否如此吗？@darrinm-不幸的是，是的。iBeacon框架实际上与核心蓝牙是分离的，其行为方式也不同。我不确定这个回答是如何接近于回答这个问题的。问题是：“我能把自己宣传成一个灯塔和一个可以提供服务的外围设备吗？”。此回复将广告作为信标进行讨论，并尝试检测信标。
