Just to emphasize: "Long Range Bluetooth" should give much more than 2m and is possible with Bangle2.js (not Puck though as far as I know).
@user140377: Did you get feedback from people? How far does shownearby work?

Glitch - special to Circles Clock or hint to general problem?
Wanted to try out cutting edge 2.15.93. Got also 6 app updates (including launcher and circles clock now 0.16). So don't know really whether firmware or app is to blame.
Now if going back from launcher via button only the left circle is visible, rest of clock face is missing. Going back with tap on upper left arrow works fine.
This is reproducible here, also after a reboot.
@Gordon Not a big deal for me. Wanted to let you know in case this is symptom of some general problem before it goes into a stable 2.16
[Update]: Hmm, now bootloader was updated (was not shown before?)
Now effect seems gone.
Have a look here, that might be an example of what you search (access and graph raw and filtered online at watch display)
(just paste to WebIDE and send to watch to try)
In case you don`t know: there is a recorder app that does record the raw PPG data from the watch directly to a csv on PC or phone:
You can also check that code as an example.
if you need to dig deeper, check the HRM calculation from raw in C here:
I very much appreciate you caring about privacy and thinking about it from the get go.
Actually privacy concerns with other watches is what brought me to bangle!
So I would vote against enable by default and for a pop up (if upcomming once and not every time).
That said, knowing your intents and pseudonomisation I am happy to provide data here. I did turn on, re-connected, then off again. Not sure though if that was enough (guess so from your ">Pretty much all of the above")
What I personally would like most is a button: "Send now" (which could be annotated with explanation of what data, how anonymized and how used).
Maximal control, transparency and ease.
Would also be interesting to feed test data to that blob to see how it compares (as kind of a "at least that is actually possible" SOTA).
Could that blob maybe somehow integrated into the test harness ? @Gordon
[in case it does not actually set registers, which I don't know]
Thanks a lot @user140377.
Have made links to your analysis and literature from my summary.
Try same in a dark room. If I remember right it will not turn off there. So I think its only the brightness that is measured.
That can be beneficial for isWorn, but only in one direction: not worn if bright, but unknown if dark.
And yes, those values are readily available. (eg see https://forum.espruino.com/conversations/384077/#comment16877590)
