If you have Tizen 4.0 it might be connected with privacy policy. Please try use requestPermission method. You might check permission by checkPermission method. It it return PPM_DENY then modify onhrmControlBtnClick method in your code to

/* Defines the error callback. */
function errorCallback(error)
{
    console.log("The following error occurred: " + error.name);
}

/* Defines PermissionSuccessCallback. */
function permissionSuccess(result, privilege)
{
    console.log("User's action for privilege " + privilege + " was to: " + result);
}

function onhrmControlBtnClick() {
    console.log("onhrmControlBtnClick() called...");

    tizen.ppm.requestPermission("http://tizen.org/privilege/healthinfo", permissionSuccess, errorCallback);

    if (hrmControlBtn.innerHTML === TEXT_START){
        console.log("info on button = start");
        startSensor();
    } else {
        console.log("info on button = stop");
        stopSensor();
    }
}

I tested on my device and after I accept this privilege, application start working properly.
