iOS nRF51822=iBeacon？

Question

我有几个nRF51822传感器，我想开始玩iOS iBeacon设置。我遇到的问题是为了

- (id)initWithProximityUUID:(NSUUID *)proximityUUID identifier:(NSString *)identifier;

你需要知道传感器的位置。查看CLBeacon文档，这似乎是传感器的只读属性，但如何/从何处读取

- (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI

我看到kCBAdvDataServiceUUID有一个2500的字符串，但我认为不是这样。有人有什么方向或见解吗？

谢谢

Answer 1

您使用nRF51822传感器构建的设备将通过iBeacon协议发布ProximityUID，据我所知，该协议尚未发布。在此之前，玩游戏最简单的方法是使用另一台iOS设备来宣传它的存在。UUID本身就是您定义的东西。

这篇文章很好地概述了你需要做什么。

Answer 2

UUID必须在BLE设备的广告数据中设置。这里有一篇博客文章描述了广告包的逆向工程。使用这种格式，您可以为您的BLE传感器制作固件，iOS将其识别为iBeacon。

一旦您有了一个知道UUID的工作信标硬件，您就可以使用CLLocationManager的-（void）startMonitoringForRegion:（CLRegion*）region查找它
