Is it possible to programmatically turn on/off/auto the wifi in a wearable web TIZEN app? Like from a js function in tau.js? I have seen documentation for natively turning on/off, but I didn't find samples/documentation for a web app.
No, It's not yet. Though you can check the WiFi status from web application, But it's not possible to turn on/off WiFi from Tizen web application yet.
