I think you missed some good news - http://forum.xda-developers.com/g-watch-r/orig-development/mod-enable-wifi-ldz22d-t3122529As far as I know we have no WiFi in our devices. A rumours says we get ot in 3Q this year.
That is the default behaviour of the wifi.Sincerely I ask the same question, or is it possible when out of range of bluetooth, activate the wifi automatically.
Thanks in advance
