附近的Google API无法找到Eddystone信标

Question

我尝试使用Nearby API使用Swift扫描 Eddystone BLE ，我已拨打同样的电话：

if let messageMgr = self.messageMgr {    
        let params: GNSSubscriptionParams = GNSSubscriptionParams.init(strategy:
            GNSStrategy.init(paramsBlock: { (params: GNSStrategyParams!) -> Void in
                params.includeBLEBeacons = true;
            }))
        subscription = messageMgr.subscriptionWithParams(params,
            messageFoundHandler:{[unowned self] (message: GNSMessage!) -> Void in
                self.messageViewController.addMessage(String(data: message.content, encoding:NSUTF8StringEncoding))
            },
            messageLostHandler: {[unowned self](message: GNSMessage!) -> Void in
                self.messageViewController.removeMessage(String(data: message.content, encoding: NSUTF8StringEncoding))})
    }
}

但是!!!我检测到 0 beacon ，你可以在我的屏幕日志中看到它：==＆gt;

也许我错过了什么？
