Tracking temperature using telemetry

I’m following the example given on the Estimotes developers doc. Code is as follows

package e.user.estimotetelemetry;
import android.os.Bundle;
import android.util.Log;

import com.estimote.coresdk.recognition.packets.EstimoteTelemetry;
import com.estimote.coresdk.service.BeaconManager;

import java.util.List;

public class MainActivity extends AppCompatActivity {
    private BeaconManager beaconManager;
    private BeaconManager bm;
    private String scanId;

    protected void onCreate(Bundle savedInstanceState) {
        beaconManager = new BeaconManager(this);

      /*  bm = new BeaconManager(getApplicationContext());
        bm.setNearableListener(new BeaconManager.NearableListener() {
            public void onNearablesDiscovered(List<Nearable> nearables) {
                scanId= beaconManager.startTelemetryDiscovery();

        }); */
        beaconManager.setTelemetryListener(new BeaconManager.TelemetryListener() {
            public void onTelemetriesFound(List<EstimoteTelemetry> telemetries) {
                for (EstimoteTelemetry tlm : telemetries) {
                    Log.d("TELEMETRY", "beaconID: " + tlm.deviceId +
                            ", temperature: " + tlm.temperature + " °C");

    @Override protected void onStart() {
        beaconManager.connect(new BeaconManager.ServiceReadyCallback() {
            public void onServiceReady() {
       //         scanId =  beaconManager.startTelemetryDiscovery();  // This line shows up an incompatibility error as : incompatible types required java.lang.string found void
    protected void onStop() {
     //   beaconManager.stopTelemetryDiscovery(scanId); //incompatible types required java.lang.string found void

It’ll be great if someone could help with this. Thanks in advance!

I see you are using old SDK which is deprecated for ranging and monitoring. You should use Proximity SDK for that. See
What problems do you have with your existing code? I see you commented line that starts telemetry discovery. Without it is won’t scan anything. I also don’t see SDK initialisation. Have you enabled telemetry packets on you beacons?

Hey thanks!
I’ve commented those lines here and not in the actual code. The comments are made to show the lines that are causing error.
