Indoor location problems!

I already made map-tutorial.
and now I’,m trying to Indoor Location with this Link - https://developer.estimote.com/indoor/ios-tutorial/

but in my tutorial code , just this message is printed.

I think that this message means there is no signal…?

    }

    func applicationDidEnterBackground(_ application: UIApplication) {
        // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
        // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
    }

    func applicationWillEnterForeground(_ application: UIApplication) {
        // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
    }

I think that tutorial and this code are same
help me please

These messages are unrelated to Indoor Location. I assume you see no avatar moving on the screen? What device are you testing on?
