Not able to access 3 axis and temperature in Telemetry Packet using Estimote Stickers (nearables)

I was trying to use down below code in my app, but it seems no luck.
I do not see anywhere in the code that specifies which stickers it is tracking.
Could anyone help to point me in a right direction?
I really appreciate it!


class ViewController: UIViewController {

let deviceManager = ESTDeviceManager()

override func viewDidLoad() {

    let tempNotification = ESTTelemetryNotificationTemperature { (tempInfo) in
        print("beacon ID: \(tempInfo.shortIdentifier), "
            + "temperature: \(tempInfo.temperatureInCelsius) °C")
