Estimote iBeacon error: Service not available

Question

我正在研究 Estimote iBeacon 项目，它将显示 iBeacon 的属性。现在，我的应用程序显示了 iBeacon 的许多属性，但我想更改 iBeacon 的主要值和次要值。当我更改 iBeacon 的 major 或 minor 值时，出现错误消息，即 "Service not available."。这是我的代码，有人可以帮助我吗？

谢谢。

为了能够修改信标的任何设置，您需要先连接到信标：

ESTBeacon connect

请注意，这是一个异步方法，您需要等到 ESTBeaconDelegate 的 beaconConnectionDidSucceeded: 方法被调用后才能开始写入信标。

此步骤的一个先决条件：使用 Estimote Beacons，只有信标所有者授权的应用程序才能连接到它。您使用 ESTConfig setupAppID:andAppToken:. The ID and token are created and retrieved from the Estimote Cloud web dashboard at http://cloud.estimote.com.
