issues with the HRM

Hi - is this with the 2v13 firmware, and all the apps are up to date? And the Bangle is seated nicely against your skin? I forget now but I think some of the KickStarter watches had a protective foil on the back, so worth checking for that.

Maybe you could have a look at the HRM-raw values using the Web IDE. Run:

var h;
Bangle.setHRMPower(1);
Bangle.on('HRM-raw', function(hrm) { h=hrm });

I'd be really interested to see what kind of range the vcPPG values are in.

This is the kind of thing I see on the one I have here - which is obviously a lot different, and you can see the values seem a lot more 'analog' out of it:
