Fail to get value from heart rate monitor

Heart rate monitor(https://www.arduino.cc/en/Tutorial/Genuino101CurieBLEHeartRateMonitor) in my Genuino101 is able to work.
However, I can not get values (a graph) by nRF Toolbox for BLE v3.0.1 (in iPhone5, iOS9.3.2).
Moreover, "node_modules/noble-device/examples/hrm-device HeartRateSketch" fails to get values (There is no word after "notifyMeasument").
On the other hand, LightBlue in my iPhone succeeds to get values.

What is wrong?
