• Detect charging or on wrist

  in Bangle.js • 2 years, 3 months

  

  Maybe I have something that suits your needs:
  I wrote a little helper function to get only the isWearing value from HRM-raw.

  Here a little example:

      checkIsWearing(
        (isWearingStatus, messages) => { print(messages[isWearingStatus ? 1 : 0]); },
        [
          "You are not wearing the watch.",
          "Yor watch is on your wrist or on a surface that appears similar."
        ]
      );
  

  The return function is called with the isWearing-status as first and the passed data as second argument: returnFn(isWearing, data);

  Here the code of this function:

      // define function to check if the bangle is worn by using the hrm
      function checkIsWearing(returnFn, data) {
        // create a temporary object to store data and functions
        global.tmpWearingCheck = {
          // define temporary hrm listener function to read the wearing status
          hrmListener: hrm => tmpWearingCheck.isWearing = hrm.isWearing,
          // set default wearing status
          isWearing: false,
        };
   
        // enable HRM
        Bangle.setHRMPower(true, "wearingCheck");
        // wait until HRM is initialised
        setTimeout((returnFn, data) => {
          // add HRM listener
          Bangle.on('HRM-raw', tmpWearingCheck.hrmListener);
          // wait for two cycles (HRM working on 60Hz)
          setTimeout((returnFn, data) => {
            // remove listener and disable HRM
            Bangle.removeListener('HRM-raw', tmpWearingCheck.hrmListener);
            Bangle.setHRMPower(false, "wearingCheck");
            // cache wearing status
            var isWearing = tmpWearingCheck.isWearing;
            // clear temporary object
            delete global.tmpWearingCheck;
            // call return function with status
            returnFn(isWearing, data);
          }, 34, returnFn, data);
        }, 2500, returnFn, data);
      }
  

  I am using this in the 0.10+ version of sleeplog:

• Sleep log only working on right hand

  in Bangle.js • 2 years, 9 months

  

  I tried it several times but sleep log only works if worn on the right wrist (Bangle 2). On left wrist it always detects no sleep. I did not change any settings yet. Do you have any ideas?

  This a really interesting occurrence. I am right-handed and always wear my watch on the left wrist. This is how I tested the app and set the default values. I never tried to check how the data changes on the other wrist.

  Actually I'm working a lot on the app and there will be some major changes and improvements on the next version. For more detailed information you may take a look on this issue in github.

  For a faster solution I would recommend to try the power saving mode. Over my test I experienced a quiet similar behavior in both modes but the hardware varieties might be less noticeable. As a result, you might not need to change the default values for the power saving mode.

• BangleApps repo changes (apps.json removal?)

  I would love to have all files belonging to an app inside its own folder.
  I think it will also make it easier to fetch the upstream on a repository with added apps.
