• issues with the HRM

  Thanks for the fast reply !
  It is 2v13.
  The HRM app is... now up to date.
  The strap is tight, and there is no foil on the sensor.

  Most of the time, values are still off.
  For instance now when I'm typing this message, it gets wild.
  Vibrations issues maybe as I read on another post.

  But after about 30", sometimes more, of being idle, the values match as in the attached video.
  Then, even idle, values goes off, and come back oscillating.

  I had this when values were off:
  { vcPPG: 2925, vcPPGoffs: 0, isWearing: true, adjusted: false,
  vcCurrent: 41, vcPre: 868, vcPS: 1062, vcEnv: 0, vcIRQ: 23,
  vcRaw: new Uint8Array([23, 109, 11, 21, 0, 100, 3, 38, 4, 0, 0, 0]).buffer,
  raw: 2925, filt: 4548, avg: 645, isBeat: false, bpm: 164.5,
  confidence: 0 }

  And this when the value were in sync:
  { vcPPG: 1177, vcPPGoffs: 0, isWearing: true, adjusted: false,
  vcCurrent: 40, vcPre: 886, vcPS: 1085, vcEnv: 0, vcIRQ: 23,
  vcRaw: new Uint8Array([23, 153, 4, 20, 0, 118, 3, 61, 4, 0, 0, 0]).buffer,
  raw: 1177, filt: 4759, avg: -101, isBeat: false, bpm: 63.5,
  confidence: 40 }

  I saw confidence 100 sometimes too.

  I had big hopes being a javascripter and having an HRM on my wrist I could program. So I participated to the Kickstarter campaign.

  However the values given by the HRM didn't make any sense. And I dropped it for a few months. But after reading some posts here about HRM.
  I just updated it to the latest firmware.
  But the readings didn't improve.

  Here's a video of both values taken, by the bangle and a chest strap linked to my bike computer.
  I verified counting my heart beats for 15" and they match the chest strap.

  Is this the sensor that has an issue ?
  If it is a software issue, would you mind to tell me where on github I can find the source and try things ?
