Is there are way to retrieve heart rate bpm and confidence by calling a function rather than using a listenner ?

I am wondering if there is a way to retrieve the heart bpm and confidence values by polling rather than using a listenner. In a multiclock format - the problem for me is variables being out of scope when the listenner gets called. I can do it with a listenner (as I have done with GPS fixes that I wanted to share between two multiclock watch faces) but it would be much simpler if I could just do

` let bpm = HRM.getBpm(); let confidence = HRM.getConfidence();

Hi - there's nothing at the moment. I think right now the listener is probably the best way...

Here's the kind of thing I have started doing so I can turn an event driven interface into a polling interface.

function HRM() {

HRM.prototype.toggleHRMPower = function() {
  this.log_debug("HRM.toggleHRMPower()");
  if (!Bangle.isHRMOn) return; // old firmware

  if (!Bangle.isHRMOn()) {
    this.log_debug("HRM.toggleHRMPower(powerOn)");
    Bangle.removeListener('HRM', onHRM);
    Bangle.setHRMPower(1);
    Bangle.on('HRM', onHRM);
  } else {
    this.log_debug("HRM.toggleHRMPower(powerOff)");
    Bangle.removeListener('HRM', onHRM);
    Bangle.setHRMPower(0);
  }

  // poke the hrt widget indicator to change
  if (WIDGETS.widhrt !== undefined) {
    WIDGETS.widhrt.draw();
  }

HRM.prototype.getBpm = function() {
  return this.bpm;
}

HRM.prototype.getConfidence = function() {
  return this.getConfidence;
}

HRM.prototype.onHRM = function(hrm) {
  this.bpm = hrm.bpm;
  this.confidence = hrm.confidence;
  this.log_debug("onHRM:(bpm)" + this.bpm);
  this.log_debug("onHRM:(conf) " + this.confidence);
}

let hrmObj = new HRM();

function onHRM(hrm) {
  hrmObj.onHRM(hrm);
}
