Some notes on the meeting:.
I showed my new Pinetime smartwatch. And answered some questions. I thought that'd I could say more here.
So it has a small touch screen, Bluetooth connectivity, accelerometer, heart rate monitor.
CPU is a chip made by Nordic Semiconductor. It is basically a Bluetooth that is smart enough to be a microcontroller or CPU. It is used by some other watches too.
You use a connector app on your phone to send info back and forth via Bluetooth. The shop I use is open called Gadgetbridge.
Pinetime doesn't run Linux but another open source OS. Ships with open real time OS called Infinitime. Supposedly there is another supported OS called WaspOS.
First time config (date and time) was done via the phone app.
This watch was only about $25. So don't expect it to be like the high end Android or Apple watch. So no LTE modem and mic and speaker like the Apple watch.
Pinetime is a very interesting device. Battery lasts about 3 to 4 days. Phone app sends notifications. Step counter seems to work. Heart rate monitor jumps around so not very useful. The sensor is a green LED pulsing on the bottom against the skin with a detector next to it. Send like the OS should do a moving average, so why would the numbers be jumping around so much?
Ok I just wanted to send a quick note. I hope this is understandable. I am on mobile and trying to shoot this out before work.
