Don't forget to flick the switch under the battery to on! I was very frustrated with it not working for a few days and then during one of the trouble shootings with a multimeter I noticed the batter is doing fine and the switch is the only place that has power. flicking it to on made the watch start.
Note that this is not a smart watch meant for consumers. this is a smartwatch meant for creators and tinkerers. Don't expect it to be perfect user experience, expect it to be a perfect development platform and with that mindset, looks like they have delivered.
Wristband is small I can barely wear. Wish this was USB C
Fantastic to have access to a low power watch… for LORA testing.
I bought this not so much for myself but for someone else. I'm sure this is something he's really going to enjoy once he gets his hands on it. I don't have enough experience in programming like he does and I think this is going to give him something that he can play with and show off to his buddies and co-workers.
The T-Watch 2020 serie was great, but it had its issues, like slow display, low autonomy...
This version fixes all those issues: the display is (relatively) blazing fast, the battery is bigger, and USB OTG support is added, I also enjoy the addition of a lora chip (though i'd like to have both LoRa and GPS).
The only downgrade is the new AXP2101 power management cannot measure current or power draw, which was very useful.
