Clock accuracy Bangle.js 2

so just on the order of 26 ppm. I do not think that should be problematic in any way since the firmware uses 50ppm by default?

Exactly, that should be fine.

... but thanks for the hint on the PPM setting - looks like the 20->50 change I made was applying for older SDKs, but would never have had any effect for Bangle.js 2! I've just tweaked that.

Odd about the systick/RTC thing - I wonder whether it's related to the peripheralPollInterval (it goes into low power mode after 1 min of not moving). Not sure why that wouldn't work though
