Estimote android telemetry problem with Samsung Galaxy 7

Hi,
i*m trying to receive telemetry packages via beacon manager startTelemetryListener. On 2 different android phones.

Galaxy 5 mini (android 5.0) receives the telemetry data ok and the data can be read, but Samsung galaxy 7 only finds telemetries, but the List<EstimoteTelemetry> telemetries is empty. Is there a problem with Android Nougat?

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