Retrieving state of the different SoC devices

Hi all,
currently we can easily check if the LCD is on with isLCDOn().

As far as I can see there are (for now) no corresponding functions for

• Compass
• GPS
• BLE
• and HRM

Is there another way of getting the status, e.g. by reading a pin status (which ones?) until we have convenience functions for this purpose?

Did not check for thoroughness for the specific pin request, but has this reference been reviewed?

I found them but wasn't sure if I could work with them in case they don't fire.

I worked around with this code

Bangle.on('mag', (() => {
  console.log("mag received");
  compassEventReceived = true;
}));
    
Bangle.on('GPS', (() => {
  console.log("GPS received");
  gpsEventReceived = true;
}));

Bangle.on('HRM', (() => {
  console.log("HRM received");
  hrmEventReceived = true;
}));

// Wait two seconds, that should be enough for each of the events to get raised once
setTimeout(() => { 
  Bangle.on('mag', () => {});
  Bangle.on('GPS', () => {});
  Bangle.on('HRM', () => {});
}, 2000);

The only issue is removing the eventlisteners now. The code above fails to do that. I already posted another question for that, though ;)

Thanks - I'm afraid that would appear to be the best bet for now. I'll add that to the next firmware though.

In terms of removing listeners, you need to have a named function so you can remove it...

function magListener() {
  console.log("mag received");
  compassEventReceived = true;
}
Bangle.on('mag', magListener);
// Wait two seconds, that should be enough for each of the events to get raised once
setTimeout(() => { 
  Bangle.removeListener('mag', magListener);
}, 2000);
