Samsung Galaxy Watch 4 5 Yes that is a Wear 3 device

yschimke · Answer

You can use the Wearable Data Layer directly to send data

yschimke · Answer

yschimke · Answer

The GitHub project is 100 standalone so won t help you

yschimke · Answer

There are some higher level abstractions in the Horologist library for detecting devices requesting play store install launching remotely and a DataStore abstraction They all just build on top of the Data Layer

lam bui · Answer

Currently I learn how to connect from smart phone to wearos which is blutooth Besides is there any other way

yschimke · Answer

A lot of the datalayer functionality can work device to device over Bluetooth or through cloud if you are both connected to internet

yschimke · Answer

If you mean directly over a socket on a local Wifi it should work but I don t have any good examples

A server hosted by Google that securely end to end encrypted connects you watches and mobile as if they were near each other for the data layer
