Libre support may well come in the future but for now the focus is on G5 / G6
This question will be answered in more detail soon. The short answer is yes it can work but you cannot have more than two devices total connecting to your transmitter.
There is a charging clip that attaches to the watch which connects in to standard USB. Full charging takes approx 2 hours.
Data from xDrip core is retrieved by xDrip+ phone app and then should work with AAPS, but more community feedback is needed to ensure everything is supported correctly.
The watch should be splash proof, like washing hands etc but is not considered waterpoof for immersion in water. No swimming, bath or shower etc.
It has BT connectivity only. There is no Wifi or cellular within the watch.
No, the display lights up when the front of the watch is tapped or the wrist is flicked when using the motion wake feature or under certain other conditions.
No, the watch uses a custom embedded system which is much more lightweight. It starts up in only a few seconds and uses much less power.
Yes it just follows what is set from the phone app
Make sure you are using Native mode with the OB1 collector (the default setting). In the future it may be possible to not use Native mode but right now that is how it works.
